You might want to lube your engine stand pivot point. It's supposed to rotate a lot smoother than it did.
Nice video because of you I am learning a lot about my 4.0 242 block things I need to pay attention to
Awesome! Thank you.
Thanks Dale, I've been enjoying this series!
Cool. Thanks!
This may sounds funny, but I found that Paint & Epoxy Remover (I used Jasco brand) worked fantastic to get that insanely hard oil buildup off on the timing chain cover (Inside and out). It's also safe to use on aluminum. Took a few coats and some scrubbing but it removed every bit of it very fast.
Humm... Good advice. I may have to try that. Thanks 👍
watching your videos cause a guy I know has two tjs one with a blown engine and another thats going out. hopefully I can get learned.
I am currently fairly deeply into a frame-off restoration of my 2003 TJ. I plan on a full rebuild of my 4.0L but then hope to sell it. I will use it for funds and experience before building and installing a Chevy 350 with TBI. I am so excited to embark on these two long-term projects, but I have to clear out my carport of several other projects before I can get back to the Jeep. Your videos have certainly motivated me to get on the stick and transmogrify a pile of car parts into an empty carport. Great vids. I have watched about ten and just started this series. I have liked them all and just now subbed. I look forward to the rest of this series. Thanks for posting them all!
Cool. Thank you for following along 👍
Great videos! Learning allot from you! I'm just about to pull my engine and rebuild it :D
Very cool! Thanks for watching
Very good Videos, love them! Thank you.
Thank you!
Drum n bass 👀♥️
gracias a tus videos e aprendido muchas cosas acabo de comprar un yj 87 6 4.2lt y lo quiero arreglar corre bien pero ocupo reparar muchas cosas viejas ahora soy un suscriptor de ti canal. thanks man take care..
¡Gracias por seguir mi canal! Lo aprecio.
Pulled my water pump and saw the harmonic balancer was bad. Watched your video foe pulling that, very encouraging. Now that i am into it, I am thinking about changing the timing cover gasket. I recently did the pan gasket. It looks like from your video that I can remove the timing cover without removing the pan. Is that correct?
What size is the 3 bolts you used in the puller to get vibration damper off?
Was there a plastic chain tensioner in there and did you replace it ?
I use my hammer drill on everything I rarely use my ratchets anymore and on Phillips screws those were old days take away way too much time
Seeing that chain slack makes me wonder about my 4.0L now.... I kinda hope the slack measurement is at least within tolerance... I already have enough Jeep projects...don't want to have to be worrying about a timing chain now too....lol...
Haha! It's always something, Huh?
Me too I’m wondering if my tj needs a rebuild of the timing chain I have 130,000 miles on mine
Just looked. 149k on this engine
My understanding of timing chains (at least for the 4.0 engines) is that they don't need to be replaced unless they're causing a problem/you notice an issue with how the engine is running. So an engine rebuild/major overhaul service is a good time to do it like Dale is doing but is not a part of "regular" maintenance like a timing BELT would be on a different type engine. Regular maintenance/oil changes should keep the the chain happy.
Thanks to your video !!
I was step by step watching my mecanic refreshing my 4.0 until finish but I never see that he install the little pin “ truss pin”” he finish a week a go and I wasn’t secure if he put it in I open the time cover surprise no pin I was looking for it I found it I install it my self thanks to your video but I got a question what happens if miss the little pin and don’t install it ?? Any problems?? I still have that in my mind I was thinking just to leve it alone .., but I fixed thank you
Curious if you’d know the answer. I have a completely busted off vibration dampener on a 4.0 in my 04 wrangler. Nothing to grab onto. Can I unbolt timing cover & pull off to give me more of the balancer side to put groove in to allow puller
Is there an orientation for the fulcrums in the rocker arms? They have small oil valley s that are tapered and the rocker arm has a tapered oil valley grooves in the bottom of them too
Nice video
Thanks!
Is it better to put pan back on first and then when the pan is on do I put timing cover on with rtv with on the gasket that is connected to pan gasket?
All sludges up!
I used to do stuff like this but I learned (the hard way) that a nice re-manufactured long block is the best way to go. $1800 or so for the 4.0.. lot cleaner and better outcome. Like your videos as you are a very good wrench turner- not being critical here, just saying so others may consider.
When I was a mechanic, my single most utilized and productive tool I could not live without was my 3/8” Air Ratchet. It will save you hours of time.
In my opinion its worth any extra money to buy a quality timing chain and gear set, and not use a generic one in a rebuild kit.
Check out the Cloyes 9-3127. Heat treated forged gears true roller. It’s worth it! Amazon $139
The air ratchet is great for limited access areas, but on the engine stand the butterfly rules for speed.
Question where can you buy the guid pin if you lose it
I’m having issues like engine noise
I m thinking it’s the timing chain
And piston slap
It’s a 02 4.0
What do you suggest I do
Cheers man
friend you speak from Colombia need solutions a doubt and your me you can help, I have a Jeep Wrangler yj and not going logged in the body of the intake valve to part of the temperature sensor are 4 holes after the body of acceleration. hoses connect to this ??
Hola.
Thanks alot for your videos we really aprecciate your work.
I have one question:
how often do you sugest to change a timing belt??
i know some people says ... `dont touch it untill it gives you problems`.
But, im about to change the seal of the cover and i would like to take advantage of that and change the timing belt.
I have a Jeep Tj x 2005.
Gracias.
Timing chain(these Jeeps don’t have a belt) typically doesn’t need replaced unless you’re doing a rebuild. If it has a lot of slop it would be worth checking the condition of the rest of the engine. You could start with a compression check.
Hi Dale, great vid! That chain is so slacked that it looks like it was slapping the cover. There is a rubber part (chain snubber) that is supposed to be inside the chain cover to prevent this but yours appears to be missing. You'll probably want to buy a master rebuild kit that contains a new gear and chain set.
Good eye! You caught that the cover was missing the plastic insert. I have a master rebuild kit I will be going over.
I’m pretty new to the Jeep game (90 4cyl yj), but didn’t the 6cyl engines have a multi plate toothed chain rather than the ansi-like roller chain? That chain looks like a 4cyl chain.
It's off the 6 cyl I'm working on.
And took my timing chain cover off yesterday and it looked exactly like yours. Do you got to replace that little seal where the crankshaft comes out?
sincitydude 72 It’s a good idea to do it if you already have it out. I just did my timing chain and water pump today and the gasket kit for the timing chain was $15 for everything. Cheap and worth it.
Hey, I was just wondering if parts from a 1993 jeep wrangler are compatible with a jeep from 1994 and vise versa. Like would a hardtop from a 94 fit on a 93 ? any help would be great. thanks
YJ wrangler is from 1986-1995 and generally should be all interchangeable between those years. Yes a top from a 94 will fit a 93.
@@bunnyofdoom87 thanks
Holy crap what a dirty engine. Oil changes are your friend!
Yeah, it was a mess!
and people wonder why there shit doesnt last! LOOK AT THE INSIDE OF THAT ENGINE. that oil was never changed
there's a tool for removing lifters
How many miles does that yj have?
149k. Less than my daily driver. Haha
Yeah.... think that timing chain is done Dale 🤔
Lots of slop in it, huh. I need to measure how much, maybe make a video..
JeepSolid sounds like a good idea Dale 😊 enjoying this series so I know what I’m looking at latter with my “Heep” lol 😆
Ok, so the black tones in the cat's coat are not natural... :D
Don't know why I'm watching a fail video
Fail video?
@@JeepSolid oops...sorry man ..dont know why it posted here ..i was watching people fail videos...awesome job you are doing man ..sorry about that
next time lift from the engine and rotate.
Don't buy the dnj kit to rebuild your 4.0 such poor quality i couldn't use it
