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?

[@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.

[@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.

[@ricardovelez300]

Don't know if it has been mentioned anywhere else but, I just took out my 2003 4x2 XLT engine out for a complete rebuild...It's got a 4x4 balance shaft unit ... Definitely OEM installed. We are first and only owners; never worked-on by anyone else before..

Yup. Whatever’s left on the assembly line from the previous year they throw in.

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! :)

[@iamdjnam]

I double checked everything with the OTC tool. It was good to go. Keep those cams clamped and you’ll be fine.

[@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.

[@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

Hey brother What about that top center cog that the chain attached to? Is that just a roller for the chain to move on?

[@blessedjuggernaut]

I bought a 98 Ranger from a guy at work. He was asking $2,500. When I went to look at it at his apartment, it blew his mind that it wouldn't start. He told me it needed a fuel pump. So told him I'd think about it, and a few weeks I offered him $1,500 for it. Ended up giving him $1,900 for it. Replaced the fuel pump which cost $700, but it still didn't run. Then after taking it to another mechanic, I found out it needed an ECM. So I got one for $90 off Ebay. Put it in and the truck ran, but it was making this hellacious tick. My first thought was the lifters were shot. Turns out it needs a timing chain. Now I've got $3,000 into this truck and I'm looking at having to pay someone to pull the motor and replace the timing chain. Boy, did I get screwed. And when I bought the truck off this prick, he pretended like it was in tip-top shape. I went off the man's word and the guy lied to me. Now he's telling me it always had a noise and he just used thick oil to mask it. This is a lesson to be learned but I'm out $3,000. What should I do? Have the timing chain replaced? Put another motor in it? I've thought about selling it on Craigslist and maybe trying to get close to what I have in it, but I would have to let the buyer know what is wrong with it. It is a great looking truck, but when it's running you can hear the noise from a football field away. He knew this when he sold it to me. Like I said, learn from me. Don't get screwed. Don't go on what a car or truck looks like on the outside. You can't polish a turd.

Yeah so that plastic piece pushes the seal in exactly where it needs to be if you didn’t press it in enough. I always make sure it’s in good shape. I’ve never pulled a 4.0 on a manual, I can’t imagine it’s much different than the auto.

I'm pretty sure my camshaft has been turned out of place

I have my heads off and did exactly everything you showed, I noticed one of the cams slightly rotated just a hair and isn’t perfectly parallel to the head anymore. Do I rotate it back to parallel then install the cam holding tool to make it stay put while I put the new chain on??

[@iamdjnam]

Yes

[@bluegill2030]

@@iamdjnam when I get all the chains and cassettes on, I can turn the engine over by hand, make sure everything is ok, then put the timing cover back on?

[@iamdjnam]

@@bluegill2030 yup for sure

[@noconsentgiven]

Can you do this without taking it out of the vehicle?

[@iamdjnam]

Yes but I don’t recommend it.

[@ronaldterry2234]

Why you didn't put the oil pump drive back on

[@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

[@rudyramos4816]

One of my front chains are broken I really wanna take it upon myself and replace it my self I just need the proper tools

[@iamdjnam]

It can be done yourself just step by step

Thank you for this video 🙏🏾

[@pwatkins70]

so i just used these and changed all my chains, cassettes, gears, and tensioners. i thought i did it correctly and triple checked everything, but when i turn the engine over now there are spots where the tensioner guide will pivot, causing varying slack in the chain as the tensioner pushes in and out against the guide. is this normal? i cant seem to find and faults in how i installed it

[@iamdjnam]

Completely normal. Once the engine is running oil fills the tensioner and it won’t move like that.

@@iamdjnam man i cannot express the peace of mind you just gave me lol these engines like to throw one curveball after another. this is day 3 of working on her and i think i needed to hear some good news for once!

[@iamdjnam]

After working on these engines it makes me want to buy a Tahoe with their old iron block pushrod v8.

Great job great video!! Bravo!!!

If one head was 180 out do u think it will bend valves

[@OverlandingJoy]

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

[@iamdjnam]

Yup.

[@aapachebird]

I threw a timing chain, and preparing to remove the engine I have had it 17 Years and has 248124 thousand miles, dropped the oil pan and was full of plastic pieces . I came across your video of rebuilding the 4.0 but have never done it. I am thinking of throwing a used engine in there to get her running again and then rebuilding my current motor. I am mechanically inclined and have done almost all the work on the vehicle through the years. your video makes the rebuild look pretty easy I was amazed actually thought it would be harder, do you think a novice can do it just hashing it over in my brain and could use a project but would also need to get the specs and everything from you if i attempt it. just want to get your thoughts on it

[@iamdjnam]

I rebuilt my first 4.0 in 2015. Never touched an engine in my life. Took me 2 months but I did it, still running today. Cheap route is throw a used motor in it. Rebuilding yourself with quality parts will cost you upwards of $2k.

@@iamdjnam cool thanks for replying and the thorough videos big time help

[@Charlieglock]

Hi There: Do You Use The Same Bolts That You Loose Or Use A New Ones On The Camshaft ??

[@iamdjnam]

Reuse
