Real proud and thankful for this video. I need to make this fix too. To be sure, I believe my timing chain and sprockets might be OK, but I need to verify my sprockets and chain is timed correctly because my distributor will not set right aligned with the hold-down bolt hole. It is a tad-bit off by about 3-5 degrees. Yep, I have TDC on #1 and my distributor is temporarily pinned for 2.5L (not 4.0). So, I figure if I need to pull the cover to verify, I might as well change out the sprockets and chain. About $64 to $76 including the gasket.

Love the channel, Currently doing the timing chain on my 99. The rubber chain guide was in a million pieces when I took the cover off. Was definitely the cause of the rattle on my engine. Thanks for the videos, you’re one of the few channels that goes in depth on these 2.5Ls engines cheers!

One thing I don't understand is why they didn't provide that tensioner on the 4.0L. At least on mine I don't have that piece. Sure would make taking up that slack better on these 4L big time. It's just the plastic piece and that's it.

You are correct. The bigger 4.0 doesn't have that piece. I think it should also. Thanks for commenting!

My 95 lost a chain and stuck a valve through the piston, valve broke in 3 pieces so yes they will

@ForceBuilt 2 ай бұрын

I don't know what to tell you about that. The 4.0 and 2.5 engines are non-interference though. I took my timing chain off and rotated the engine around multiple times getting the dots to line up on the gears for correct timing. No interference on mine.

Great Video! Thanks for creating it. It's been super helpful. I'm afraid the guide is in pieces at the bottom of my oil pan. Anyone have any recommendations to removing the pan without having to mess with the exhaust? At first look it does not look like there would be enough room to remove, but I might be mistaken.

@ForceBuilt Жыл бұрын

Thanks Corey! I don't have any experience with that. My guide was missing and when I did my engine rebuild it wasn't in the oil pan either. I personally would replace the timing chain with the new guide and not worry about that. The chances of it sucking to the oil pump screen would be very slim. Have you had the cover off yet?

@coreyhall5898 Жыл бұрын

@@ForceBuilt Yep, took the cover off and found broken pieces still stuck under the metal "clips"....(I believe you referred to them as ears), the spring was loose just sitting there (it didnt fall into the pan) and one other broken piece I didn't notice that fell into the pan when I touched the chain . That piece fell into the pan near the opening and I was able to blindly find it with my fingers and pulled it out. I'm just wondering if there are any other pieces in the pan. You're probably right....slim chances of it sucking up but do you think I should be concerned with smaller pieces potentially being in the pan?

@ForceBuilt Жыл бұрын

I really don't think you have anything to worry about. But that is just me, doesn't mean I am right. I think the risk is very low. If it was starving for oil, your oil pressure will tell you.

@coreyhall5898 Жыл бұрын

@@ForceBuilt One more question regarding the timing marks. When I rotate the gears, I can get the marks almost lined up but when I apply pressure when turning to get them 100% accurate, they don't stay lined up after I back off the pressure from turning (they go back to "almost" lined up. I'm not sure if this is common or if I'm close enough. If I do another full rotation, would that change anything or would I end up with the same "almost" mark position? If you don't mind I thought about emailing you (to the email address below) a picture of my "almost" marks to see what you think.

@ForceBuilt Жыл бұрын

@@coreyhall5898 sorry for the delay. I've been mowing the grass. One more rotation will not matter. The compression is what is pushing you back. You can remove spark plugs to keep that from happening. Hope this helps!

With a faulty tensioner or faulty guides would the noise be more noticeable at idle? Would it also increase with rpm? I’m having a slight knock but only at idle. When I give rpm it goes away. Would a compression test show anything with the pistons?

@ForceBuilt 7 ай бұрын

It will be more noticeable at idle. If it is a lower pitch sound it could be something else. Mine actually had a broken piston skirt. I have a video showing how bad it got when it finally went completely out. It is the first video in my engine rebuild playlist. Thanks for stopping by!

@@reedcarpenter2994It can be either way sadly. Before mine broke off, the more rpm the less I heard. After it failed, the more RPM the faster it made the sound.

How did you go about setting the timing?

@ForceBuilt Жыл бұрын

Very easy to do. With the timing cover removed, the 2 gears have dots stamped into the edge of each of them. At the closest point between the gears, rotate the crankshaft until the 2 dots point directly at each other(at the closest point between both gears). Now remove the 2 gears and chain. Replace with new gears and chain, making sure the dots are in the exact same spots as they were before you removed the first set of gears. Hope this helps!
