Now I had a a company replace my two tensioners and my thermostat housing 3 weeks ago because I was too busy now I have the cassette all shattered. What is your take on the antifreeze under valve covers? The oil is still relatively water free and not milky but oil cap has moisture?

[@iamdjnam]

100% normal for the cap to have moisture. Don’t worry about it.

Thanks for the vid. My 06 explorer blew the guide, poked it out the valve cover. The cheap easy way or to the dump she goes, got my money out of it already but we did it this way. Quick tip on that extra balancer chain, chop it off with a small bolt cutter, no mess, chopped right through it. New guide 30 bucks, ebay valve cover fifty bucks (probably could have used JB weld), tube of black RTV six bucks.

My 2005 Explorer 4.0 has 188K on it and so far, so good on the timing stuff.....I will be putting a Reman in it for around 3500.00 if anything goes bad.

[@maovegas]

When I did my first 4.0 swap in my 07 Limited, your videos were not around. They would have helped alot, good work. As it happens I am pulling it out again, no compression on any bank 2 cylinders. We'll see what's what when I get it out and crack that head. My question is about the balance shaft. In one of your timing videos you removed the chain and sprocket all together. I believe you said you don't need it. My rig is a 2 WD, of course I will do a complete cassettes and guides replacement when I have it out, how can I be sure removing my balance shaft chain is ok for my vehicle. One less part of the 4.0 timing job is fine with me. You do good work, well done.

[@iamdjnam]

Funny you should say that. When I did my first rebuild there weren’t any videos. That’s why I started making them. Get rid of the balance shaft. It makes no difference and is one less rotating part.

[@iamdjnam]

If the cams don’t line up, you jumped time and bent the valves. You need to do a leakdown test to confirm.

[@ThomasShelby-uq8cz]

What do you do if you take everything apart without marking anything or holding the camshaft in place? How do I get my timing, right? I have a engine with the timing chains off but not sure how to get the camshaft in the correct place along with the time gears because they aren't marked and free spin. I'm pretty sure my camshaft has been turned out of place

[@iamdjnam]

You need to watch my head gasket video where I go over timing and how to properly use the OTC 6488 timing tool kit. The engine does not have timing marks or colored links. You need to have a confident understanding of this engine or you will destroy the valves

[@darrinsonnier9424]

I cut my balance shaft chain off with bolt cutters. Worked pretty good. Did not feel like messing with the jackshaft. The tensioner for the balance shaft chain came apart. I heard the rattle under acceleration. I immediately stopped using my Explorer and started surgery. I deleted that chain and replaced all the guides and cassettes. Only 125k and the engine had been previously been into. Found all the front head threads for the brackets heli-coiled 🤬. I’m at least on my way back together with it.

[@socram321]

You say at the end that you checked your work with the tool. And? I'm assuming no adjustment needed. ?? I'm glad to see this video. I'm assembling the entire engine. I start with pistons and crankshaft tomorrow. I'd like to NOT have to pay for shipping for that timing tool. I'm actually asking a smith to make me a valve spring compressor from an old crowbar. I can press them fine with the head off, but once it's timed, I'm going to need something that doesn't clamp from underneath the head (and I don't want to install the head with the rockers in place and under pressure.) Exciting stuff! :)

Excellent video!!!! Can you answer the following? 1 . Time (hours) to remove engine outside? and 2. Time (hours) to install engine back in place? Thank you very much.

Hello! Please tell me after replacing the replacement of the repair kit on a Ford Explorer 4.0 sohc began knocking and began to pour oil from the valve cover of the left head into the intake manifold in the 3 and 4 cylinders because of what it may be? Thanks!

[@iamdjnam]

Did a chunk of plastic come blasting thru the valve cover?

[@DIYJeff]

Hey @Platinum Productions, you're videos have been a lifesaver as I break into my daughters 4.0L 2005 Ford Sport Trac. Quick question though. I have the valve covers off, but not the harmonic balancer and timing cover. Those are my next steps. I am planning on replacing the front timing chain because I did a compression test on cylinders 2 & 5 (middle cylinders on each side) and 2 (passenger side had 225lb compression (seems awful high) and 5 had zero compression. I did the test to see which side had lost compression because I suspected the engine jumped timing. My daughter was driving it and it shut off on her doing 55mph. And won't start back up. In fact, it turns over very slow. It's not a battery or alternator problem. Can a blown head gasket cause this same symptom? When I took the intake off, there was a significant amount of coolant puddled on the top of the engine block. The engine is still in the vehicle. I appriciate your very informative and intuitive step-by-step explanations in your videos. I try to follow the same approach when I make my videos.

[@iamdjnam]

Yes depending on the location a headgasket can cause low compress

[@malikmobster]

Hey do you think we can replace the balance shaft easily does it come right of when pull or ????

[@iamdjnam]

You have to remove the upper oil pan to remove the balance shaft. You can take the chain off and just leave it off. The shaft will stay but just not be operational. That’s what I do.

[@malikmobster]

Thanks for your reply but I need to replace the balance shaft itself I accidentally broke the front tip of the shaft I had my car jacked up from the front and it slipped of the jack and fell right on the harmonic balancer do you think I can do this without taking the engine out ?

Forgot to mention it’s 2010 mustang v6 4.0L

[@iamdjnam]

@@malikmobster are you talking about the balance shaft or the harmonic balancer??

[@iamdjnam]

@@malikmobster ok. Then you’re talking about the harmonic balancer. Yes they can be replaced with the engine in the vehicle. It’s very simple.

Platinum garage, what is the name of the bag on top of the engine underneath the intake manifold, what is it for...????

It’s a sound dampener. You don’t need it. I always throw it out.

Hello, good night, a question and they go don times that he changed the chains and this happens to me, he eats the guide of the chain in front and he runs out of time that could be

[@iamdjnam]

The engine could’ve jumped time due to bad or worn out guides. You need to check that you didn’t bend valves before proceeding with this.

[@MetalMusic1134]

Are the slots on the camshaft perfectly flush? Super exact? They don't both lean slightly in or anything?

[@kjjerome]

Hi Nick in all of your videos I haven’t seen any thing on installing the front cover around the crank, did I over look one of your videos? I may have found my moisture problem in that I have pitting around the water ports. I remember one vid where you applied black rtv in the corners… would you or do you dab around the water ports? Thx

[@iamdjnam]

It’s shown towards the end of my headgasket video.

[@stevenfountain5236]

Do I need to pull motor to install the chains

[@iamdjnam]

Front no back yes

[@johnnycotrel7413]

Hi.I have a few questions hoping you might be able to answer.We just bought a 2006 ford explorer xlt sport utility and i think its the 4.0 in it. We tried starting it but it almost acts like its out of time.Is the timing a common thing with these engines?Also do the engines need to be out of the vehicle to redo the timing?And if the timing did go on this vehicle would it have hurt anything else like valves etc..?Thank you

[@iamdjnam]

Hello. The vehicle can be timed with the engine in it. Although you can’t replace the back timing components with the engine installed, it would have to come out. And yes, if the engine is out of time you will bend the valves.

[@tomspecht4733]

can we replace the cassete on the rear if we have the transmission removed? I have a 2007 mustang with this engine and was thinking it might be a good time to replace the rear timing chain guides and tensioner

[@iamdjnam]

Yes!! Definitely replace the cassette while you have the access with the transmission out.

[@tomspecht4733]

@@iamdjnam Is this doable with the engine still in place in the car? The transmission failed so I had to remove it to fix worn out servo pilot holes.

[@iamdjnam]

Yes but you gotta remove the intake and valve cover.

[@reynaldobarboza2029]

Bro I had some one change all these chains on my explore and it still has some raddeling in the engine any idea what they did wrong

Cheap hydraulic tensioner probably not holding pressure. Grab a set of Ford or melling.

Great Video but is it ok to eliminate the balance shaft chain??

Yes

What size socket did you use to rotate the crankshaft for tdc?

[@denisdenis2034]

if your theory of 4 stroke engines is good no special tool is needed to time the camsshafts Simply put the cylinder no: 1 at top dead center and position the lobes of the cam must point upwards at 180 degrees from the rockers. then according to the order of fire put the cylndre no: 2 at the top dead center and do the same thing and it's done.

[@briancraft777]

I got everything torqued down and turned the engine over by hand a couple times to hydraulically charge the tensioner per cloyes instructions. The right bank cam stopped turning all of a sudden after a thunk that echoed out from the exhaust manifold. The left bank cam will turn with crank and stays in time but the right will not turn anymore. What has happened?

[@iamdjnam]

I have no idea

[@briancraft777]

@@iamdjnam could it possibly be the new rear jackshaft bolt that just broke? I hope those torque to yield bolts aren't that weak. I torqued it to 15 ft lbs then 90 degrees

Yes but I don’t recommend it.

[@nofortunatesonII]

Why did Ford put the balance shaft chain on the engine if not needed? Is it true that it is only used on 4WD models?

[@iamdjnam]

They put them because engineers hate mechanics

[@dnseal]

Thanks for posting your many how to videos; well done. My current situation.... Full engine rebuild (with your guidance) and engine ran Great for 1k or so miles, but now oil pressure fluxuates from good to zero. I'm sure its not the oil pressure sensor as engine noise varies when pressure drops out. The ONLY part I did not replace was the two center jackshaft bearings and my research indicated this is possible cause; spun jackshaft bearing My question is it worth another engine removal to replace these bearings? I see the process won't be too involved or should I suspect further engine damage from particulates in oil causing further damage to other bearings and simply trash the engine? Have you delt with such a situation? Be well Gil

[@iamdjnam]

The engine must be removed to replace those bearings.

[@dnseal]

@@iamdjnam well that goes without saying.... my question was/is. Is it a positive gamble to replace these bearings post rebuild and now that oil pressure issues has shown its ugly face or is the possibility of greater engine damage not worth the effort? Engine has less than 1k miles since full rebuild, to include heads, full timing kit, piston rings, main bearings, oil pump, water pump, seals, gaskets, etc.

[@iamdjnam]

@@dnseal install a mechanical oil pressure gauge and let me know what it reads. Not the stupid idiot light on the dash that shows normal even when it’s only 1psi

[@dnseal]

@@iamdjnam great idea and I was going to do so until I related pressure drop with engine chatter that occured simultaneously. Pressure goes back to steady; noise goes away. Pressure drops; engine chatters. I was hoping it was oil sensor issue, but signs point to spun jackshaft bearing; the only part I did not replace.... my bad. By the way, the reason for rebuild was that engine overheated; bad. My concern is if bearing damage distributed metal slivers (stuff) in engine oil and that inturn has damaged the rest of the bearings (main, piston etc) which are all new. Replacing those means all new TTY bolts, bearings, gaskets, and engine teardown. Heads, pistons and rings should be fine. I guess, my next step is to drain the oil and tear apart oil filter and see if there is metal visible. Normally, like you, I'd just have at it and redo tge engine but at 58 and recent stroke on august 26, my abilities are not what they use to be... smile Thanks for input, keep up the good work and although click, likes and whatnots seem to matter these days; the knowledge you possess has a far greater value. Be well Gil No

[@dnseal]

@@iamdjnam was just reviewing your "Ford 4.0l SOHC V6 Complete Rebuild Part 1/2" and I see at the 15 minute mark you jump right into front "drivers side" timing chain cassette installation. You already have the jackshaft in place; did and or do you replace the two jackshaft bearings on these rebuilds. I myself have rebuilt a few daily driver engines and typicaly do not replace them; I did on my performance engines. Sadly I did not replace on this daily driver ford engine and should have. I found a video on oil pressure fluxuation and cause; I will forward a link post this comment for you thoughts. In my case this seems to be the cause of my oil pressure dropping out. Be well Gil

[@OverlandingJoy]

I was quoted $2900 to replace front and rear timing kits. Is this reasonable?

[@iamdjnam]

Yup.

[@strwbrryswisher420]

I have a question if anybody would be willing to answer. DIY mechanic here, the guides on my front cassette broke and i'm in the process of replacing it. Just curious is there a way to just replace the guides on that chain without having to pull the cam sprocket off. My biggest concern is me getting the engine out of time. I don't have the means to pull the motor so i'm currently doing it with the motor still in. I see how you managed to do it without removing the jack shaft sprocket and chain. But I haven't seen anybody do it without removing the front camshaft sprocket.

[@iamdjnam]

You can’t pull the cassette without removing the camshaft gears

Many years ago, I bought on EBay a new ADP Timing Chain Kit. Is this brand name junk and don't recommend using it or can I get by using only the chain guides from the kit?

The 91 is a totally different engine.

@@iamdjnam Im not sure.I bought the vehicle and she said the fuel pump went in it so im guessing it did just stall out but they also most likely continued to roll it over trying to start it back up and of course with me only going by what she said i also rolled it over to see if it would fire.Im only a half assed mechanic so could you explain the leak down test.Thank you for the reply,i appreciate it

[@iamdjnam]

Basically you thread a hose into the spark plug hole and charge the cylinder with air. Charge to 100psi. Any cylinder that holds below 70psi fails the test. So if you bent valves it would show 0
