Compression test result:
1 - 190psi
2 - 185
3 - 190
4 - 185
5 - 195
6 - 190

mechanic said engine is fine, as long as theres no more than 10% difference between the highest and lowest psi readings.
just curious how much psi is a perfect 6a12 engine hold? 200psi?

190 is pretty much on the money there

just a quick question. Where did you get your compression test done and how much was it?
