I am looking for some advice and help here. I just bought a 91 4runner with a 22re. I have been looking for the 22re and 5 spd for a while. Here is the issue.

Noise coming from the engine. Not sure what it is, I do hear one value making noise, hopping it came be adjusted out. But there is another rattling sound. My guess is it is the beginning of the end to the timing chain. Truck still runs, but I don't want to do any major damage to the engine. The truck has 202k miles.

So what to do? Do I attempt to do a timing chain replacement, and hope that solves the problem. I do not want to spend alot of money on it if I can avoid it.

Any Help?
