I have a 4cyl/2.7L 1999 Toyota Tacoma w/a little over 82K miles on it. I believe I have a timing chain, not timing belt on it? And was wondering, if it is a timing chain, whether or not I need to replace it and when (ie: mileage)?

Should be a lifetime part. If you rebuild the engine for any reason replace it, otherwise leave it alone.

What ^^^^ He said. I have never seen an actual chain go. It is always the guides which i believe they improved for the 2.7 from the 22r

I kinda disagree. Chains get streched out over time and need to be replaced. I had to replace one on my old 22RE. It got to the point where the chain had worn into the side and was mixing anti-freeze w/ the engine oil and vice versa. This was around 170k miles though.

That's the guide problem Ike talks about:

Yep. I should have clearified that. Once the guides are toast the chain can do lots of damage. If I'm in there to replace the guides, I'll replace the chain as well.

if you do chanis in a 22r replace with a dual row chain and steel guides.......will never have a problem again.........never saw a 20r have the chain problem, they came with dual row and steel guides..................
