Okie So I was working on the corolla. Fine tuning the engine mounts for the s2000 engine and I thought i do a compression test because I never did one when I got it.. it looks like this

1. 240
2. 270
3. 250
4. 260


Does this look right to you guys? I see cyl #1 has a looks pretty low so I have no Idea. I dont even know what is the standard psi they are suppose to be at. I just thought i post it up and hopfully say my engine is not messed up in a way.

 

Okie I check a few other thread and these numbers seems to be wayy off LOL

people are AVG 220 why are mine soo high..

my engine has about 44,000km

and I tried this mulipule times with 2 compression testers both gave me the same values. I pluged it in open the throttle all way and start it.

 

I believe that each gauge measures differently, meaning that one compression check from one gauge can be different compared to another make. In other words, the measurement accuracy cannot be compared with each other. I know that to find good engines you check the compression and all of the cylinders would have to be within 5-10PSI from each other.

Correct me if im wrong....
