I just replaced my timing chain because I thought the old one had way too much play. The new one looks the same. Just under 3/4" play side to side. Is this correct? The manual says if the chain has more than 1/2" play to replace it. The old sprocket had some marks on the plastic tips from the chain, but otherwise looked ok. The new sprocket is all metal.There is no detectible slop in the crankshaft or the camshaft. Has anyone else had similar experience?

File comment: this shows how much I can pull the chain outward after placing the ruler with chain pushed in.

It's too bad you already bought a set. I would've suggested going with a 4.0L double roller set and adding a cam button while you're in there. The plastic tipped gear is a POS. Getting rid of that is a good thing already. What brand is the timing set? I recall some being recalled due to production issues in China.

I did a timing chain last October, using a Cloyes part from O'Reilly. The original was almost as sloppy as the new one you're showing in your photos, and that was after 170k miles. The new chain, while not taunt, is nowhere near as sloppy as your pictures show.

You already know there's no adjustment on the timing chain. I am almost willing to bet you got a faulty new chain. :eagle:

Not really wanting to switch it out. Just put the transmission back in the car today. Engine went in yesterday. Also, since I'm in Norway, it will take more time to get the new one. Maybe I'll just see how the car runs before I decide.

Any good timing chain set has both cam and crank sprokets. That might be where your slop is from that crank gear looks old to me.

Mine was still running quite well before I changed the chain. The only reason I changed it was because I could hear the chain slapping the timing cover. I can't tell by driving the car that it runs any better after replacing the chain than it did before.

Replacing the chain with the engine in the car is not all that hard. I took out the radiator and shroud but left the A/C condenser in place. Pulling the radiator gave me enough room to get my puller onto the end of the crankshaft to remove the balancer.:eagle:

I replaced sprockets and chain as a set.

Just started the engine up a couple days ago. Purrs like a kitten. The new sloppy chain is certainly keeping the timing more on target than the old sloppy chain. I also removed most of the unwanted vacuum, egr, and charcoal stuff. That may be helping as well. The engine has never run so smoothly as now. I'm satisfied.
