Opinions on compression test numbers, please.
I'm planning to go with a Rotrex kit down the road. I might even be upgrading it a bit (200 - 220 whp). So, I did a compression test (thanks for the help, Kuksi).
Front to back:
#1: 203 psi
#2: 199 psi
#3: 182 psi, 188 psi after a bit of oil
#4: 199 psi
We were a little short on time, so we only re-tested #3 with oil since it was a bit low. From what I understand, these figures are still within factory specs but what are your thoughts on that 3rd cylinder? Is it a problem and if so, what is likely the issue? If I decide to fix it, what else should I consider doing at the same time?
