3vzfe compression question - Toyota Nation Forum : Toyota Car and Truck Forums

What is the compression supposed to be on these engines? I've looked at two and one guy told me it had 190lbs per cylinder and theother guy told me 175lbs. So if I know who was feeding me a line I would know who to not deal with.
Thanks

I have been told a bunch of different things regarding CP testing. I was told buy a SAE certified tech that the main thing to look for is that all cylinders are even. CP testing results should nope be the only test you do, but a place to start. If all your cylinders are around 180 and one is 160, you may have a problem.

Other than that, I am not sure.

178psi normal
142psi min

I wouldn't start any big performance mod if any of them are under 160psi, or one is more than 20psi away from another. The stock head gaskets are too fragile.

Please make sure of the search feature in the future. This has been covered many times.

Thanks, and yes, I did do a search multiple times but didn't find what I was looking for. I found a lot of unrelated stuff talking about pretty much everything else though.
