Ford Quick Tips: #46 What To Inspect Everytime You Remove a 5.4L 2v Intake Manifold

[@1keykneedeep]

I watch these videos religiously. Top notch advice and training

[@exteriorized]

Yes love the tutorials. Here in mid 2023 this is one of the rare areas of YT not affected by Woke ness , just real science on auto repair

[@Riptides99]

I've tackled the same cracked plastic problem shown in the video with my 5.4L F-150 and had success in eliminating the O-rings on the cross-over and filling in the plastic channels with a suitable high-temp, plastic repairing, coolant resistant epoxy to repair and reinforce the intake before sealing the two surfaces back together with RTV on assembly. I'll note I left a shallow groove in the o-ring channels for the RTV to bead in. I did this about 15,000 miles ago and have yet to have a problem. I'm not suggesting anyone do this, but it's something to consider if you're comfortable enough working around engines and understand what issues may arise later from doing so. When I did that I also took the time to replace leaking valve cover gaskets, install a new thermostat, change the plugs, and have my injectors inspected and cleaned along with new injector O-rings installed while it was all broken down. I did follow a previous video by Makuloco on removing the intake to replace the intake gaskets, which I also did since I had it all apart.

[@gregnuttall3637]

Thanks for the information. Just now took my 5.4 intake manifold off. Gonna need the whole intake, busted right where you were pointing on the Left side.

[@stephenmaestas6426]

I had the number 1 spark plug go bad about 2 years ago and replaced the whole set. ( I learned about Ford's infamous design flaw during this procedure) About 4 months ago, it was the number 1 coil pack that died. Soon after replacing that, I noticed steam coming out of my hood after arriving at work one morning. Looking for the source of the steam led me to find a leak on the number one injector seal. Great, I've got coolant AND fuel leaking like crazy. I replaced the eroded O-rings on the number one injector and all the other injector O-rings on that side for good measure. That's when I found coolant pouring out of the area between the plastic and aluminum intake parts. That had to be the source of all the other problems. As fast as it is leaking, it must be the like the one in this video. Mine is a 4.6L with 176K miles on it. Plastic has it's uses but not in engines. Ford isn't the only manufacturer doing it, though.

[@elttabykcir]

My 99 ford f150 5.4 liter has the aluminum intake manifold, I'm glad that I don't have to deal with that plastic one! They crack and warp too easily. If mine ever gets damaged I hope that I'm able to find another aluminum one just like it.

[@vezsschino]

03 CVLX with 197k. I have replaced the intake manifold with Ford OEM only. IMHO there are certain things you must stick with factory parts and this is definitely one of them. The redesign of the coolant crossover was supposed to fix the issue of cracks and eventual leakage, but in regards to your great video.... those coolant crossover gaskets are a bad problem. even with my brand new FRPP intake manifold I could have been in some big trouble if I hadn't double checked those crossover bolts from the underside before install. They turned out to be snug, not right at all and on top of that I recommend adding some COPPER RTV besides the gasket.... to me it's just not thick enough to keep a tight seal under the elements of hot and cold. Same goes for the actual manifold gaskets as well. There just isn't enough sealing gasket material. If I owned my own shop it would be difficult to guarantee my work when I know plenty of 2v owners go through the issue as well.

[@ykmalachi]

I changed about 3 of those intakes on my 4.6 Crown Vic engine I swapped into my vintage truck. Gave up on that and bought an aftermarket all metal unit and never had the problem again. I feel it is very much worth the price to end the problem forever. I bought the polished unit, but you can get a raw aluminum one for around $300. It works with Explorer, Mountaineer, Crown Vic, Mercs and Lincoln Panther body cars as well as the Mustang. Cost is under that of the OEM unit. I have used the Dorman, which works, but my issue is the sheet metal screws used for holding down coils and injector rails. The holes only take so many removal of the screws before stripping out.

@@famousneu1 the same inlet cracked on my stock aluminum intake, 97 4.6 in a 7lug f150. I put the plastic one on. This all started because it leaked coolant in the plug hole from gasket failure. There was also gasket failure in some of the runners. Truck has 250-300k miles which is a guess because the odomoter had the failure prone plastic gears in it.

[@alb12345672]

Be careful with the 4.6L and the dorman intakes. They are a universal design now and introduce vacuum leaks if you don't RTV the old locator holes in the cylinder head. There are two different designs floating around. Be sure to test fit to see if you need rtv! The documention to do so isn't always included.

[@aaabbb-p8h]

@@mtsanchez27 As of July 2024, Ford re-released the 4.6 2v intake manifold. M-9424-P46A is the new part number on the 'updated' 4.6 2V manifold. It has been tested on the dyno and unfortunately is not as good as the original intakes Ford equipped and sold as a service part. The new part has lost hp and torque and has much shorter runners, but it does have a few other changes. Other items of interest are the updated design to the coolant outlet at passenger rear (plastic not metal as some have implied) in addition to the crossover being all aluminum instead of aluminum fastened to plastic. New design eliminates the fatigue the Zytel GF30 P66 material faces with some old manifolds with reference to this video. Overall, better than a lot of the aftermarket plastic intakes (keep in mind, while zytel with glass fiber can be injection molded, many aftermarket are made using only a thermoplastic with properties subpar to the P66 nylon) this is made by same mfg as Dorman in the USA (MPI), just carries the Ford name and warranty.

[@nicholaselias8542]

funny story...back when I was in college and started DIYing cars, I had a 96 crown vic police interceptor. That thing was my pride and joy and I had save up a whole 900 bucks to buy it. I had a cracked intake manifold that was leaking so I was going to change it out and was going to do the thermostat while I was at it... Well to make a long story short I was short one bolt in the end and thought I would get a new bolt put in place and then I started the car and my heart sank... I opened the intake back and to my horror I did exactly what I thought I did... I let a bolt slip right down the intake... that was the first, only and last time I ever made that rookie mistake!!!!!lmao. ALWAYS ALWAYS inspect the intake/ exhaust ports for fallen parts and once you confirm it stuff a rag, a glove, whatever down there so that you dont make an expensive mistake like I did lmao To this day I have night sweats when I have to open up an intake worrying I might do that again to a mercedes or something lol

I finally figured it out. at that specific engine speed/load my coolant was spraying onto one of my coil packs causing a short.... changed out the intake with the cheap doorman option and its all good to go. didn't really notice a noise difference but i wasn't looking for one. defiantly not worth $200 more for 5db less noise..

There was an upgraded version of this intake that fixed the leak issue. I'm also aware this issue is from over heating the vehicle and you get that stress fracture. I'm not sure if it cools down to fast from cold if it will cause the problem. Maybe install an ice shield around it would not hurt.

[@Banshee365]

Yea, the Dorman I take is inferior to OEM as is about everything they make. I've installed several Dorman intakes for customer cost reasons. I almost declined the work if the part was Dorman but I sort of wanted to see the differences. The main differences to me were the gaskets integrated in to the bottom of the intake rather than having separate ones like Ford always does. Also, only the throttle body has brass threaded inserts. Every other fastener for the fuel rails, coils, and different bracket mounts are plastic holes with self tapping screws. It's really cheapy to me for that reason BUT I havn't seen one come back yet.

[@FordTechMakuloco]

+Banshee365 Good info I knew about the integrated gaskets but not the self tappers.

[@jr7441]

I have sold many of these to my customers. Like Brian said it's cheaper to buy a Dorman compared to the OEM. It seems that a lot of the shops will always go for the cheaper intakes. Though they are putting a less durable intake for their customers. The gaskets do change so the customers have to be aware of they the factory intake or the aftermarket.

[@Banshee365]

+Jose Romero You're right. Most every consumer wants the cheapest. That's why it makes me so happy to see guys like Brian advocating OEM parts. It's so important!

I have a 2001 5.4 on my expedition. I suffered the same crack and leak as shown on this video. I replaced the ford intake with the Dorman. I couldn't be happier!!! The design is so much better for the following reasons. First and foremost the box on the bottom of the intake is much smaller allowing servicing the knock sensor, the water pump pipe and the water temperature probe without breaking you knuckles of having to remove the intake. If its noisier as a result I sure cant tell. My engine sounds great! I also like the courser thread they use on the screws they provide because they take less turns to tighten and seat. Especially the bolts that hold down the ignition coils! Speeds up the tedious process. Why would I buy a more expensive ford OEM that doesn't allow me such access and failed already in the first place???

[@ScientistPrepper]

That's interesting. I'm fixing to do this on a 2001 5.4 Triton on my F250. Found the intake on Amazon $106, but I'm afraid of the louder engine now due to the comment in this video. Don't want to waste $$ on a brand, but I love how quiet my engine is for a 23 year old truck.

I cannot believe that they made it out of plastic.

[@kingjames8283]

While I don't currently have a problem with the intake manifold on my 2003 4.6L Crown Vic, I do have to wonder why Ford didn't just make these manifold/runners out of aluminum to begin with instead of alum/plastic as in this case and the one on my car. At this point in time, I am not aware of any aftermarket mod's by Edelbrock or others to improve this design for the 4.6L, 5.4L and 6.0L Ford Modular engine series.

FordTechMakuloco, I am not a mechanic, nor would I say mechanically inclined. I have a 2001 F150 Supercrew. Retired, so cannot afford a new truck. I love this truck and get compliments on it all the time. Haven't had to do much work on. So happy there. That being said, I just had this problem. Took it in for repair. The mechanic told me it was PCV Valve, PCV Tube, and something around the throttle body (don't recall the part). Anyways, I took it in this morning for repair, went to pick it up and they told me it was misdiagnosed and was not the PCV stuff at all, that it was the Air intake and it was cracked. So I go to start the truck and feel it shaking. It wasn't doing that before. It shakes at idle. So, I tell the guy before he locks up shop, he say bring it back, he'll get it ironed out. So, I drive home, and under acceleration, it shakes worse than at idle. They replaced the air intake manifold, O2 sensors and sparkplug boots. In your video you talk about O rings, and gaskets, etc., I don't see that on my invoice. What could be wrong? I should just take it to Ford and get it done right! So tired of paying for dealer service, but when I do, I don't have problems. The place I went to is a world leader in automotive repair. I don't take my stuff to any backyard mechs. Nothing against them, I just prefer the peace of mind of proper work done, and guarantee with said work.

I just recently discovered a coolant leak coming from underneath the RH flange of the intake manifold.The valley of the engine block had completely filled up with coolant. I already knew what it was from research like your video and others so I decided to remove it and it did indeed have the classic broken plastic grooved gasket slot, it was pretty bad so I ordered a new Ford intake from Amazon as you suggested, (price is now around 220.00) While I am waiting for the intake to arrive, I am prepping the head surface, and decided to replace spark plugs while I have easier access, especially #3 #4 #7 and the dreaded #8, I am also replacing valve cover gaskets as they have been leaking for some time, Also unlike your video I did not have a fuel line disconnect tool so I was able to remove the intake by just popping out the injectors from the fuel rail and lift out the intake quite easily. My question to you is: should I consider replacing the fuel injectors that are 170,000 miles old. I have had no problems at all with them and I religiously change my fuel filter every 20k or so.

Injectors here in Burbank Ca can be cleaned and flow tested for about $22 ea if your not local, I am seeing crazy pricing for new injectors though.. Question you have to ask one self is just how dirty is your fuel tank over how many years and miles and factor in how timely have you been replacing the fuel filter? All that goes into how often injectors might start clogging perhaps. But, replacing injectors can be time consuming in itself and so if problems develop down the road, are you willing to have to re do a lot of work to get to them? Factor in whether you have the money now to deal with injectors as a few hundred for the cleaning and new o rings Also are you paying someone for labor or is this your time turning wrenches your gambling with. Lastly is this a daily work vehicle? How much do you loose if the vehicle goes down for the day or week even ?

Worn out thin old over aged antifreeze, worn out diluted motor oil worn out transmission fluid that has lost its ability to cool or lubricate in my opinion is detrimental in these situations. Clean new full fluids good tire pressures. People drive across Kansas or Nebraska for 10 hours and then hit the Rocky mountains and wonder why the car is going slower you're going uphill you have thinner air you have less air and your foot goes down into it and your vehicle says nope I ain't doing it. Maintenance is the key. Ford already has cooling systems on their vehicles that are too small and this is why many of these engines have head gasket issues again and again. But people ignore transfer cases changing antifreeze. I say get that antifreeze out of there every 2 years. How bad is it you drain the cock plug, tighten it up and put in 2 gallons of brand new 50/50. $22 plus tax at walmart. Good insurance

When you have the intake manifold out, what do you recommend replacing? Knock or air temp. sensors? Heater hoses? Also, is there anything else you would replace while the intake manifold is out? I’m getting ready to take mine out and just want to have all the parts needed.

[@FordTechMakuloco]

No I don't change anything else in the engine valley while it is out, just check the heater pipe for rust and the wiring for the cht sensor.

[@TheMrboombostic]

FordTechMakuloco Thank you for the quick response. Looking on RockAuto, I see 3 different motorcraft heater hoses. How can I tell which I need?

[@eddiekeeler9955]

I have a 2001 F-150 w/5.4 2v engine. I suspect that the manifold is leaking coolant. I'm experiencing misfires intermittently. I have some coolant loss. Is there anything that I can check BEFORE removing the intake manifold. I looked at the crossover pipe and it's really dirty where it mates on both sides of the intake manifold. I'll clean it up and see if I detect any leaks. I'd really like a quick response as I'm taking the alternator out to replace the voltage regulator and serpentine belt. Less work if it's already partially apart. Thank you for your time.

[@marka.2715]

I know this video is old so I hope you see this comment. I recently got a P2004 code on my 06' f150. I am going to have to replace the IMRC which involves taking off the upper intake manifold. Do you have a video on how to remove it?

[@FordTechMakuloco]

+Susie Canter No the crossover bolts to the intake from underneath as shown.

[@josephklimchock5412]

Is there a better than OEM for a replacement? My 04 E350 has 166K, loses 1 inch coolant in the coolant tank about every month, no visible leaks, so I suspect the intake. I'm not gonna pull it off without having a replacement ready to go back on. So, is OEM Ford the only way to go?

[@amarquina86]

Question does anybody know what are the torque specs for a crossover I'm a 99 Crown Victoria 4.6. I got the original Motorcraft intake manifold?

[@margaritaviveros8017]

Mine is a 99-2000 f150 4.6 and it has a aluminum one should I be worried??

[@frank8534]

My gaskets look way different then those. Any recommendations?

[@daghost6791]

I'm going through the same thing. Just outta the blue my temperature guage starting moving up while driving, after doing an inspection, hoping it was a pump or thermostat, i find out after sending to the shop that its the intake. Always kept up with the maintenance, never had a coolant issue, but the now has 204k. The shop wants $1000 to fix. Should i go through with the repair or try to find another engine and go from there

[@FordTechMakuloco]

+Mike Stone If it's just the intake go for it and repair it I have a whole video on how to replace it.

[@CenobiteBeldar]

What would you use if you can't find a Ford intake manifold? What about gaskets? Victor Reinz or Fel-Pro gaskets if no Ford is available?

[@FordTechMakuloco]

fel-pro

[@hondaguy425able]

I had a bad leak on a 4.6 mustang intake under the metal crossover as you showed. Those o rings are not replaceable on the 4.6. I could not find them anywhere. I even went down to my local Ford dealership and they told me their is no o rings between there which there clearly is. I didnt have the money for a new intake so I left the o rings in place and put rtv gasket maker on top so let's see how long it lasts.

[@LargeMuscularTitties]

How long did it last?

[@danielwilson7572]

Do you have tips on installing the intake on a 5.4 3 valve? I'm fighting with the vacuum port on the back of mine in my '07 Expedition.

[@honeybadger7320]

I found the passenger side coolant chunk wedged into my thermostat - seems to be a design flaw. The "Insulator box" below the intake -sheesh...a pile of debris. I called Ford. there are only 8 new ones left in the Country and they aint free or cheap. I am wondering if I MUST replace it too in your opinion? To me it seems like it's just a junk collector.

[@FordTechMakuloco]

It's just for noise

[@jdtractorman7445]

I have a 2008 F-150 with a 5.4L 3V engine. In the future I may have to replace the cross over tube. Do I have to remove the intake manifold to do it or no?

[@sassankarai550]

Has the design changed for the 5.4 l Triton engine? It looks like the crossover could be removed without removing the intake? I am asking since my 2010 has developed the leak at the driver side crossover.

[@marknewman6902]

Where can I get the crossover gaskets. Also is that what they are called "crossover gaskets"

[@alexanderremrey9838]

Hey Brian, I have 2003 Ford Expedition 4.6l. I am losing radiator fluid and have a #7 cylinder fault when I hooked the code reader up. I also get the white smoke out of the exhaust but not a lot. At first I thought it was a head gasket failure but I did the chemical check on the radiator fill tank and it showed no combustion gases present and my oil is clean. How do i tell if it is a intake manifold failure for sure because I don't wanna drop a bunch of money and labor into a SUV that has a blown head gasket and isn't worth the money.

[@Carlitosway211]

Hey man, so I've done quite a few of these. Sometimes that insulator is completely fucked off, and I leave it out since the dealer never has one. In your opinion, is that a bad move, or should I just keep on with it?

[@eddieaustinbex]

Have you ever seen extreme vacuum on the oil fill on the passenger side valve cover? And or crank case?

[@stacybihlmayr3646]

I have a 2007 ford explorer with 4.6 and it has a ticking sound coming from the passenger side. How hard is it to remove the intake manifold.

Yes 1997 to 2003 5.4 2v intakes are the same. I wanted to send you a picture of an 1999 aluminium one but don't know how on you tube

[@richardmiiller6513]

Well the aluminum intake has different types of ports. The plastic one had more a square type and were bigger. Would know how to keep the aluminium from sucking air.

2001 Ford Taurus engine codes Hi Brian. Your videos are amazing. Mom still has her 2001 Taurus that she got new as her retirement garage queen. It's an SE with the Vulcan engine and the AX4N transmission. The miles is 130,717. The only repair since new is 1 coolant over flow bottle. 1 PCV vacuum hose leak elbow. Several failed EGR repairs--- see below About two summers ago the thermostat stuck and she got the car hot. I replaced the thermostat and the car has never overheated again. The oil is fine, no smoke, the car runs with normal power and idle quality. Since two summers ago the car is "drinking" about 1.5 gallons a year(10,000 miles) of anti-freeze. The water pump is tight and no wetness in the weep hole. Zero coolant smell and zero signs of a leak. She went to start the car the other day after shopping in a store 6 miles from home. The car had sat for 15 min. She had trouble getting the car to stay running and it kept dying as she tried to put it in gear to take off, but then it suddenly healed itself and is running fine. Codes reveal P0401--- EGR flow insufficient. "This EGR code has shown up since 2004 and Ford could never did it, but the mpg is great and the car runs like new. New codes as of the starting crisis P1131. Lack of H02S11 switch sens indicates lean P1151. Lack of H02S21 switch indicates lean P0171 syst too lean Bank 1 P0174. Stay too lean Bank 2 The air filter is fine, fuel filter has 3,699 miles on it, trans serviced every 30,000 miles. Tail pipe has zero smoke and clean and dry. Exhaust fumes smell normal and clean. PCV valve fine Oil is fine No evidence of vacuum leaks any where What do you suggest? No milky engine oil, under side of oil filler cap clean, etc. Thanks She really loves this car and had planned to drive it to 200,000 miles. Thanks again.

[@FordTechMakuloco]

+fastrace011 Once these engines overheat they blow head gaskets real easy I think this is your concern. Also look for vacuum leaks from hoses such as the pcv hose on the passenger side they fail often on these.

I got a question back in August 2016 I replaced my 5.4 in order to get it out intake had to come off well not long after that intake started leaking water in the back around cylinder 4 never miss fired though well I decided to replace it yesterday got it back together and now it's missing bad intermittently though any suggestions. I also unplugged ever coil pack and motor changes tune Everytime I also sprayed break cleaner around intake no change

I just bought a 1998 ford f150 4.6 it has set up for 8 years. Ran ruff. He said steal gas. Drove it home and then didn't want to crank up. Pump gas pedal it will finally raise up for 40 or so seconds even with pedal pushed then die unless you feather the gas. And even then will not run a entire minute. I replaced the fuel pump assembly inside tank and fuel pressure regulator. Wounded in it the intake or gasket. Please help

[@105Ivan]

Thanks for the intake heads up. I'm not even going to look at my old one and just order a new one. While I have this 5.4 2v apart I'm looking at this engine valley and thinking of adding a drain hole out the back. Have you ever seen this done? I'm concerned about fluids collecting in there maybe even gas and causing a fire.

Thank you immensely for your videos. I have a coolant leak coming from the bottom of the cross over tube on the passenger side and am afraid I might be replacing the whole intake manifold. Amazon no longer sells the Motorcraft brand. What other brand do you recommend if Motorcraft is no longer available.

[@TonyoTorres]

what symptoms we should have if the crack is between the coolant and air passage besides coolant loss???

You would have coolant loss and misfires on that bank of cylinders as the coolant seeps into the spark plug wells.
