Hey all,

I have been looking into replacing some of the timing chain components. I'm new to these little motors but am learning quickly.

What I need to know is if anywhere sells a new timing chain for the 2.5L

Also do these chains have some sort of a tensioner under there with them?

I ask because I always like having all parts I need before I go opening up the motor. I'm having an issue getting it to stay in timing. It seems to be going 2° +/- It won't keep a steady number and now that I've driven it a bit it seems to be way off the mark that I set it on.

If anyone has answers or similar problems they have fixed let me know! Any help is greatly appreciated.

Other experts will correct me if I'm wrong, but isn't the Iron Duke one of those Chevy engines that used a gear driven camshaft (with no chain). Somewhere in the back of my mind, I thought it was just gears. And something in my possibly faulty memory says you can get a metal timing gear for the camshaft for a Chevy inline 6 and it will work with the crankshaft gear on the iron duke, and that's more reliable than the plastic/fiber gear that was used in the Iron Duke.

Of course, that's from possibly faulty memory.

Well that would make since. The pictures show it as what you would think a gear drive set would look like with reverse angles.

After a bunch of reading on here looks like the most common issues for timing problems is the gears or the distributor.

Distributor is very tight. Figure I should go ahead and look at everything with the timing gears and just don't see a chain anywhere. Must be just the gears then if that's what you seem to remember too.
