I have a 2003 F350 5.4L 2wd Every Time it rains the truck seems like it starves for gas, I use nothing but premium gas in it and cylinder 5 has given me a problem in the past with accumulating water but I have no intake leak so we put some silicone in the sparkplug well after changing the boot and it fixed it for a while but now its doing it again and no check engine light. I cant figure it out and only happens when it rains and a few days after that, then the truck runs like a dream until it rains again

[@loganhargis6626]

I have a 2000 F-250 with the V-10, mine has the 5 speed manual transmission. My 2006 F-250 has the 6 speed manual transmission. My 2000 Excursion has V-10 and the 4 speed automatic transmission. None have blown a spark plug ( knock on wood ). I attribute this to my mechanic following the correct procedure for changing the plugs, extremely important. My 2000 has 250k miles on it.

[@readmore3634]

My mechanic used to run the service dept. at a ford dealer. I have a 2000 Excursion V-10. 1. Go only to dealer to purchase new spark plugs every 80k miles, replace all 10 coil rubber boots and clean inside of throttle body. 2. If you have after market off-set rims, change out front hubs every 60k miles. 3. If you experience "theft light" issues and it won't start at turn of key, the diodes in the alternator may have failed, causing all kinds of problems with your PCM. It will continue to charge battery when running but will discharge when not running. Replace with remanufactured ford alternator. 4. If someone steals your cat-converter and damages the wires to your 02 sensors (before and after the cat-converter) it might cause the number 19 fuse (under the hood, 20 amp) to blow and render the engine limp-mode. I experienced all of this and the only real problem was the Alternator went out...big deal...took 45 mins to replace. The other stuff was caused by outside forces.

[@qualitylawncareservicesnow445]

Got a 2000 400k Miles doesn’t miss a step and most times is pulling a 4500lb lawn care trailer or my 5000lb boat! Either way 11mpg loaded and 14.5mpg unloaded. Coils are super common on these too, along with everything you stated. But really even with all these things the cost of ownership is still cheaper than most Volkswagens !!!!!

[@luisetorres5760]

I don’t own one yet, but I worked for a quarry company and fixed few times a v10 service body f350 they had. The car had 300k miles with bad maintenance and carrying a big diesel tank every day, never quit. To this day it keeps working

[@jbaker8871]

Theirs now way you get 14 mpg. I’ve owned several. They didn’t do 14 new.

[@TERRORoftheLORD]

:41 I'm gonna stop you right there . . . The 6.8 Does NOT require premium fuel. If you reed the manual closely, it says if in your climate/altitude you experience knock, to use premium. I've put around 3500 gallons of 87 octane through these engines, and they run just fine.

[@briankimmell7960]

Thanks for the video. I have a 2002 e350 6.8ltr van I work/ live out of. I've blown out 3 plugs on original engine. First time was a huge surprise. Very loud! I did research and bought the "time sert" retread insert kit. Did the repair with engine in van. Very difficult, lack of space. Extremely nerve racking. Drilling a big hole in the head is something that is not natural. Anyway, worked excellent. Had the pcv cracked hose up under throttle body as well. gave intermediate rough running. Would have never found it if someone hadn't suggested looking. Almost impossible to see on my vehicle. Engine made it to 300,000 miles then developed miked oil and gas somewhere other than in the cylinder....automatic transmission made 240,000. Just installed a rebuilt high performance engine and getting ready to fire it up. I love these engines, and love my van. Mileage is 10mpg no matter what I'm doing... yup that sucks. cheers

[@Bill-ye8tb]

Good video. I believe the 6.8L V10 is recommended for 87 octane fuel or higher. 93 octane isn't required. Coils are another common issue also.

[@Deerector]

yup... 87.. no way 93

[@davesbroncogarage]

Owners manual says 87 octane.

[@jbaker8871]

I’ve owned several v 10 never had a plug problem. Only problem is 7 mpg pulling 10 empty.

[@pj9731]

I have a 99 F250 extended cab lariat with a V10 automatic with factory 4:30 gears. I have owned this truck for 17 years and it presently has 172,000 miles. In all this time, I had one spark plug blowout (#2) and I repaired it with a Time Sert Kit myself. I did not trust anyone with this procedure. It’s been seven years and still running great! She is 24 years old now and I have replaced the PCV-short U hose three times,fan belt once, two alternators, ten OEM injectors, ten OEM coil packs and ten OEM plugs. I keep her serviced every 2500 miles because that’s all I drive it in a years time. There are no oil leaks, no exhaust leaks at this time. She has been a good truck for a first year Superduty. I still pull my fifth wheel camper from time to time with no issues. This time next year I will be applying for an antique tag! LOL!

[@ninorcsinned3465]

I have an 04 with 165k on it. I had 1 plug blow out. Did you have any trouble replacing the other plugs? I'm nervous about replacing them if they strip out the threads

[@tomfoolery5665]

Good job it's great to educate folks about problems that mechanics encounter on what folks think should be a simple job. Now maybe as they learn they will understand why their automotive bills cost what they cost. They can learn things that will save them money and it's a great feeling to fix something yourself!!

[@erikjacobson7989]

A mechanic telling you the 6.8 requires premium fuel isn't much of a mechanic.

[@davewasinski2828]

Holy cow Love this video and thanks for making me feel better about buying my new used truck for 6,800$ with less then 130k and dropping 3,300$ back into to it in order to get the helio coil fixed because of the miss firing issue and needing to replace the coil packs on to cylinders with the tune up and well now have it chipped for better gas mileage and it seems to be working as far as getting better gas mileage for a work truck. Its a 1999 but I have been looking into the spark plug blowouts and that was one of my biggest concerns about getting to the truck but holy cow its a beast of a truck this is the biggest truck I have owned in my life and its like driving a whale in a kitty pool!

[@benjaminbaez5843]

My 99 F350 Owner's manual says to use Regular 87 octane fuel and I haven't had any problems using regular fuel. Not sure why Premium was said to be required.

[@tomfrantz]

Great videos. Bought a New Holland service truck. 2003 F250 v10. 320K. Sold my 2014 ram for 30K. This truck I just bought is also "damage title" I found out after dealer sold it to me for $2700. It had perfect fluid and runs too good to be true. Looks like they did lots of service to it.

[@Nambilus]

Awesome video, the first two problems are ones I've already encountered and dealt with on my 2000, definitely a great truck.

[@fishnhomeylod462]

Bought a ‘99 from a buddy. F350, flatbed, new trans, new brakes, new coils, new Cooper tires… the list goes on and on. They got tired of putting money into it, so I picked it up for 1500. I’ve put a few hundred into it, but at 250k on the clock, this thing is a dream. HOWEVER, it makes a weird shrieking noise occasionally, hit a bump, noise starts, hit another bump, noise stops. What in thee heck!? I’m stumped.

I was watching at 2x speed guy is still very helpful but funny. I learned very fast. Thanks for putting video out you helped out a lot of people with the info.

[@grantw.whitwam9948]

I think the nausea from the exhaust is caused by the huge repair bill. Wouldn't you think the maker could have used stainless steel bolts, especially considering the vehicle cost.

[@nunnyabizness]

Right! But then you wouldn't be paying big repair bills and that's not good for business. Asian manufacturers typically use stainless or galvanized hardware because - well - they'd rather have a reputation of reliable cars and trucks. Ford engineering is the worst I've seen and I'm a long time mechanic.

Ford Exhaust ticking is very annoying its manageable if you got the tools and effort but the 03 Ford expedition Ford makes it very difficult. Auto shop book time for replacing exhaust manifold gasket on an 2003 Expedition is 4.9 hours longer than a 2000 expedition exhaust manifold gasket job. Raise the engine and lower the front differential to access the studs. Very difficult on me but I managed. Thanks Ford.

[@VAfisher141516]

Did any of the 6.8 v10s have the same 2 piece spark plugs like the 5.4 triton? If so what years have them and which ones do not? Thinking about purchasing one and would rather not get into the headache of having the 2 piece plugs snap off in the heads. It would be a huge help. Thanks!

[@AirborneRenegade]

I’d say the blowout problem is still present on newer engines, just less common. I don’t own a 6.8, but I do have a 2009 Crown Victoria with the 4.6. It blew a plug a few weeks ago. Easy to fix, just pricy. Not a bad guide for people wanting to buy one of these trying to find what can fail on them. Tritons are solid motors with a few flaws like any decent engine.

[@acuraonly]

great vid, perfect

[@travissk5036]

Great Content! Thankyou!

[@eldridge201]

A couple things I noticed that you discussed in the video that aren't correct. I'm not trying to nitpick but just want the correct info to be out there as others are watching. 1. The generation that you are working with (the 2003 model) is the 1st generation or commonly known as the "2-valve" version which was offered from 1999 to 2004. ** (NOT up to 2007 as you said in the video) ** 2. This version did NOT have 360 horsepower as you mentioned at the beginning of the video. The 1st generation 2-valve versions of the Ford V10 for the Super Duty had 310 HP and 425 lb-ft. torque respectively. The 2nd generation (more commonly known as the "3-valve" versions) from 2005 to 2010 in the Super Duty trucks had 362 HP and 457 lb.-ft. of torque. These engines were offered in other vehicles with different power ratings as well such as Uhaul box trucks, RVs, buses, stripped chassis trucks, and other vehicles. In many cases, they had different intake and head designs and some parts are interchangeable between the different engines and some are not. But that's a different discussion. For the 1999 to 2004 versions for pickups, they had the option of the 4R100 or 4-speed automatic transmission or the 6-speed manual. From 2005 to 2010, they updated the automatic to a 5R110 or 5-speed and still offered the 6-speed manual as an option. They don't offer the 6R140 or 6-speed automatic transmission for the Super Duty pickups from 2011 and newer however, they do offer this with the chassis versions such as Uhauls, buses, RVs, and other models. To my knowledge, there is no conversion kit avialable to mate the 6-speed automatic to the 6.8 V10 for pickups. So, one would need to get this from a donor vehicle of one of the vehicles mentioned above. 3. You called the valve cover a "valve cap". I've never heard anyone refer to the valve covers as valve "caps" ever. I'm sure it was just a simple mistake and I'm not trying to get on you about it but it was just odd. -------- This channel's videos are great and this one is as well for the most part so please don't take my criticism the wrong way. I would suggest just doing a simple Google search in the future when discussing particular models and engines so you have the right info. If you need to, just use a 3x5 index card to have a few notes on and refer to that. This doesn't need to be so professional that you can't use a simple index card. ---------- For the Ford V-10 engines, although you did mention a few issues that they share with the other similar 4.6 and 5.4 V-8 models such as the spark plugs blowing out on earlier models and the exhaust manifolds bolts rusting out, you didn't mention one very important difference about these engines in relation to some of the newer 5.4 engines. The fact that both versions of the 6.8 V-10 DO NOT HAVE camshaft phasers or usually known as VVT (variable valve timing). This makes this engine so much more reliable with less moving parts internally to break down. That might be one of the main reasons that these engines have been so reliable and I think it's something that is worth pointing out. If you read the various forums and other sites online or in Facebook groups, you'll notice many owners getting at least 200k and 300k and more out of these engines before they have a major breakdown. Usually. So, they are pretty reliable for a lot of miles with little money invested. And, they are a lot cheaper to maintain than diesel engines with only needing 6 quarts of oil with a filter compared to at least 14 quarts or more with a diesel. One of the main downfalls (other than what you pointed out) is that they typically don't get the best fuel mileage. Usually. Most owners report getting between 12 mpg and 13 mpg unloaded (without towing a trailer) driving down the highway. Many have said they get between 7 mpg and 9 mpg when towing a trailer. But in fairness, it's all relative to how you drive. My guess is that "most" owners of these V10 pickups are spending more time on the gas than they need to because they like to have more "fun" in the seat of their pants due to the power. So, if they would just be "nicer" to the gas, most owners would probably get an extra mile or 2 better. Personally, I own a 2002 F-250 extended cab 4x4 with 8 foot bed and with the 6.8 V-10 and 4-speed automatic with 3.73 gears. It's got 308,000 miles and runs pretty well. I get between 14 and 16 mpg if I'm driving conservative at around 68 to 73 mph with little to no wind against me on the sides or front. If I want to do 75 to 80 mph, that obviously goes down to around 11.5 to 13 mpg. But wind is probably the biggest factor in how good or bad the fuel mileage will be. Even if it's from the side, it's still not good. I use an old Superchips Cortex 2950 tuner and have it set to the "fuel mileage XS" tune to try to get the best fuel economy and run the cheapest 10% ethanol (87 octane) whenever possible. Sometimes, I'll get an 88 octane that I think is a 12% to 15% blend (I might be wrong on that) from a local Casey's general convenience store that is a few cents cheaper. But usually, I just put the cheapest stuff in I can wherever I'm fueling up. I also tow with this setting without issues and have towed over 20,000 pounds (total with truck, trailer, cargo, fuel, me, tools, and etc.) and it pulled fine so I just leave it on the fuel mileage XS setting. I've tested it with different fuel and the tow setting and performance setting and overall, the fuel mileage didn't improve over the same conditions and terrain so I decided the added costs for fuel wasn't worth it.

[@markdavis8888]

If you own a Triton Two Valve engine buy the CalVan insert kit and proactively install all of them. Do it when you plan on changing plugs and oil since that is part of the job. Costs a few hundred but you don't want to blow out a spark plug out on the road.

[@RandyYuros]

I have a 99 F350 with the V10 Triton. Bought with blown engine, did an engine swap with a used one. It runs great with excellent compression and oil pressure but have an issue with fumes in the cabin. To me it seem more like gas fumes than exhaust. Have checked all vacuum lines for deterioration, no leaks that I can detect. Is not coming from the emissions cannister output and there are no gas leaks anywhere in the engine compartment or in the fuel lines to the tank. It is enough to get a bit of a headache when sitting still or moving slow - during normal driving, can't really smell them. Ran fine without any codes this summer for about 700 miles but then threw a DTC P1131. I cleared it but came back within 25 miles. IDS shows: HO2S11 not switching correctly. Sensor indicates lean. Air leaks at the exhaust manifold (I replaced all the broken studs and installed new exhaust gaskets on the replacement engine). Freeze frame shows SFT1 and SFT2 at -3.91% and LFT1 and LFT2 at 10.94% but not sure if that is normal. Not sure if the fumes and the DTC are related - any ideas? Not sure what to look for.

[@stilltlrforlife]

Actually an exhaust leak can cause an O2 sensor code/codes and really screw up the fuel trim. It can also burn up an exhaust valve, I wouldn't say you can drive it like that long term with no issue..

[@jimspencer1077]

It explains some of the complaints I have heard about these trucks. It would be kind if you could give and estimated cost to fix these different problems. I think I understand the complaint, now, of the aluminum shavings getting into the oil and destroying the engine. I have heard complaints of these spark plug repairs that only lead to that. Not pretty.

[@florzellpaschal4405]

Hello. Great video. I have an 03 f250 with the 5.4 and 86,000 miles that runs great until it rains or gets washed 🤔. After that, it has a slight skip when idling and while driving, it doesn't accelerate well because of a skip or misfire. If you really step on the gas however, you eventually get pass the skip, but acceleration is still terrible. Again, this ONLY happens after a heavy rain or a car wash(hood closed and no engine cleaning is done during washes). After about a day, everything is fine again...

[@kftc1980]

Somewhere in front water may not be draining as it should, and is being diverted to one of the sensors, that would be my guess. Or one of the seals around the engine bay that limits the amount of water that gets in has failed.

[@joelclark3862]

Check the passenger side rear 2 spark plugs wires to see if they are worn for whatever reason water runs across the heater core hoses and drops down onto the plug wires making a puddle my 97 4.6 did this I zip tied the hoses over a little problem solved good luck

[@aarongoodwin4845]

Coil not sealed! Water getting in! Dielectric grease and make sure the COP coil is seated and sealed!

[@brokenwrench404]

As others have said check the coils and spark plug holes. Remove the coils and blow the holes out with air. Check to see if you have the rear hood weather seal. Also check the inside fuse box below the dash. Early superduty’s are notorious for the driver side windshield leaking onto the fuse box and gem module. It causes all kinds of electrical problems

Hello I’m having a problem with my 2001 f250 super duty XLT V10 triton, check engine light comes on with code PO720… “output shaft speed sensor” it’s not causing a lot of trouble just a kick in gear from 1 to 2. I’ve replaced the sensors both, transmission fluid as well. The light still will not go away. Do you have any suggestions?

[@Subvet684]

Thanks for the video, great info! How much of it applies to a 2008 Triton V8? And do you have a similar video for that year? Mine is in a motor home and I keep getting a check engine light for the fuel rail pressure out of range.

[@MrMobileAutoService]

Most of it. Except the 2008 have the spark plugs that can break when you're trying to do just a simple tuneup. Then you need a special tool to get the rest of it out. The replacement plugs won't break because . . . well they are just smarter than Ford engineers.

[@tikiman48]

Make sure you use motor craft spark plugs. I manage a fleet, and 2 2013 f450 v10s I have had champion plugs in them from before I joined. These plugs deteriorated in under 30k miles and the ceramic insulator on the plug fell off and destroyed multiple cylinders.

My 02 v10 has 231,000 miles on it. Iv never had any problems with it until it hit 229,000 miles and it blew out a spark plug while towing a trailer . My mechanic fixed it and so far so good. I hope that it doesn't do it again. I love my v10 it has plenty of power for me and it's a beast in 4x4 low 💪

2003 6.8L F350. Pings with 93 octane. Idle is Very smooth. No engine light. It will ping at cold or at operating temperature. Hauling a load or empty. Should I start with replacing the PCV valve and hose then work up to the Mass air flow sensor? It does seem to have power, but I have to ease the throttle when accelerating. 1/3 throttle at most.

Harmonic balancer on these tritions like to dry rot and separate. They will start to squeak when they go bad.

[@JHUGHES484]

Starting issue lately. I have a 99 F350 V10 service truck. lately You have to trying to start it 4 or 5 times before it actually starts. It seems to run fine but its bad if you have to sit there and try to fire it 5 times. Common? What is the common issue? Thank You Jim Hughes.

[@andresbidrogo914]

Hi buddy I got the same truck but 2000… It really is a very reliable, resistant and durable vehicle. I have traveled all over the country with it, I have pulled heavy trailers and it has never let me down, the spark plug thing is true, it has done it 2 times after 10 years with it... but I have now a P1633 what should I do? thank you

[@jacobhillanbrand7988]

I was looking to buy a 2002 f 250 with a v10. Would a compression test help diagnose if there is a problem with the cylinders?

[@aarongoodwin4845]

Yes

[@kellyh4035]

I've seen the plug go right through the head. You should mention how this applies to the 5.4 and 4.6 2v. As well as the breaking plug issues.

[@jeremywright9693]

what octain of gas should I be putting in my 2008 Ford F350 6.8L V10?

[@rhowe6513]

Bet you haven't seen this one: 2001 F250 6.8; at 87K miles got #6 misfire, pulled coil and had 1" coolant on the boot. never water on top or even rain. Sucked it out with straw and shopvac, drove another 80K miles rinse and repeat. Otherwise best truck ever, no, best vehicle ever. Work truck, airlifts for heavy loads, then snow plowed 5 years, followed by 30' 5th wheel coast to coast 10 times. Now 175K and had to replace fuel pump, otherwise virtually no expenses but tires. Terrific truck. But coolant into #6??

[@nicknick8160]

Torque spec for the spark plugs on 2004?

[@josephpalomar4445]

Nice video on the v10. Mine is a natural gas only truck. What advice can you give. No gasoline what’s so ever

[@robertwalker8622]

I hope you do a video about how to diagnose problems with this motor with an obd2 scanner

[@dan.ktrimminallday3237]

So I have had the spark plug and the exhaust problem, I had Ford repair the exhaust manifold and y pipe now two years later I’m having the same problem with the exhaust manifold....

[@sherylslaney7736]

I have a 1999. It cranks but won’t turn over. Is it a fuel pump or spark problem. I’d there any test I can do to find out what the issue is. It is cold here. High in the 30s during the day. Obviously much lower at night, in case that might also be an issue.

[@Baltimore012]

Great video they seem to be helpful. I have a 02 excursion V 10 the other day it lost all power brand new battery no lights dash lights or fire to the starter. Not sure what’s going on battery no more than two months old has anyone ever experienced this actually, the battery is about four months old. Thanks in advance for any input.

[@kazokeify]

Great info and question I have a V10 , 1999 , 115k miles .. Engine seems strong , when idling, as of lately when driving down road at any speed seems line it is missing and I hear noise like pressure blow by and truck seems there is a disconnect between engine and transmission any ideas to me I thinks it's a sensor not picking up the rpm acceleration or foot pedal gas increase and then timming is off ?? What do you think

[@spurrit]

What did it turn out to be?

[@davidcrumrine1165]

Would be great to know what it was. I have 460,000 on my 99 and it is doing the same thing.

[@josephcastillo7804]

Just bought a 1998 F-250 5.4 triton I don’t hear or see vacuums leaks but when trying to accelerate it bogs down does not want to pick up speed it does the opposite but I can hear the fuel pump turn and truck turns on fast but last owner had gas sitting for 8 months can that be the reason why it ain’t running properly also I get a code po171 , what can that be?

[@RayMainBagpiper]

Would be cool if you did a video about the the intigrated relay panel for the fuel pump and related components. Cost me $1300 in St George Utah to have the Ford integrated relay bypassed so that I could get home. Now I'm having trouble with the other integrated components on the same panel. Would be a great video to see what's involved with just replacing the whole panel instead of waiting for each relay to fail.

[@RayMainBagpiper]

Umm.. forgot to add.... had to have the fuel pump relay bypassed.

[@Joesdifferent]

You solved most of my problems but should I check each spark plug or is there a way to find out which spark plug is misfiring? I don't have the computer?!

[@DavidTroupe-lc2gz]

I have a friend with a 2007 crew cab and it lost power while towing a camper over the hills and when you start it up you can definitely hear an irregular erratic firing that sounds like a valve issue on the passenger side. I need to remove the valve cover there and inspect the cam and rockers. At the tail pipe you can feel that there is an erratic pulse of exhaust. Do I need to jack up the cab to get to this? Is there something else that I could be having an issue with?

[@Gardendreamsforme]

I have a 2003 Ford F-250 V10 Triton that always had that ticking noise… in the old days we called them tapets. In 2013 that noise became a huge loud clicking noise. I stopped driving it because I didn’t want to cause further damage to whatever was wrong. Now I’m dreading the cost of getting it fixed

[@williamwhite9767]

Most aluminum head V8s break exhaust manifold bolts. My smelly opinion is that with the aluminum head expanding more than the cast iron manifold the stress on the studs cause the breakage. Don't the rear studs tend to break first? The rear of the manifold is probably the hottest because all of the exhaust passes this point. Perhaps an aluminum exhaust manifold would fix this issue?

[@jaredborja708]

How much does it usually cost to replace those exhaust manifold studs in a 2001 lariatt v10

[@kevinwalters8886]

My 99 v 10 sputters and hesitate not sure if it's fuel spark or sticking valves it doesn't do it all the time mainly when it's warm and ecelerating hard not sure what to do about it no codes and no engine light

[@rushbayou5230]

drivers side exhaust manifold has 4 broken studs. i dread this removal. i get lots of codes for misfires. ive changed 3 coil packs and now im doing 3 more but im heading out to check that PCV hose right now ;) i have a 2000 and as far as i know there isnt any issues with blow out. when i do my plugs, i always start the truck for under a min when cold. i assume warming the block just slightly , helps. redone the entire front end and may need new steering gear. nothing cheep on this truck ty4urvid

[@rushbayou5230]

ps. im going to try the mig welder to pull broken studs

[@rushbayou5230]

i drive in the bush lots and go through mirrors more then i change the oil... lol

[@rohanboswell3752]

Nice , question? Is this the same v10 that's found in the RV motor home's,?

[@aljobes1357]

I have a 2000 Excursion 6.8 V10. I replaced all of the exhaust manifold studs due to the problem mentioned in this video. (took me a month) working on it when I had time. I bought this Monster om 2013 with 90K on it. It now has 140 K on it, 8 inch lift with 37 inch tires:-). I just ccompleted rebuilding the complete frontend minus the diff which was fine. Today I have a cranking situation with no Start. I am assuming its the fusebox in the occupants compartment. I have power at the injectors. No spark at the plugs. I have a couple relays to swap out before I dump the cash into the fuse box. The other thing I ran across is my scan tool won't complete the scan....a problem solving I go I guess.....

[@mendiviloutdoorstv]

I have 2002 ford excursion v10 and everytime I put 87 octane fuel it pings. Once I run 91 octane runs fine. Why the owners manuel say 87 octane requiered? Should I keep running 91 octane?

[@VentureWayward]

In this video, he mentioned they need premium fuel. Run fuel that gets rid of the ping. There are octane additives that may work for you. Do some research before putting them in your vehicle

[@RaidersRawesom15]

Seafoam it

[@TJ-qz6hr]

Do not run octane boosters in these V10s, it can destroy the catalytic converter, even if it says it won’t. Always use premium fuel with Seafoam.

[@atlaslion5128]

Run fuel system cleaner in it

[@willdanzeisen3844]

I have a small oil leak in my V10 and cant seem to find where its coming from seems to be a lot on the transmission case any suggestions on how to find exactly where it could be coming from?

[@aarongoodwin4845]

Rear end of the valve cover!

[@duaneharris1160]

Is there a vac hose diagram and a hose diagram for the 6.8 2002
