So I decided to do another compression test today because the last numbers seemed low, all around 220psi. The first thing I noticed is that there was a little bit of oil sitting in the spark plug holes. I cleaned them all up and plan to order some new tube seals spark plug gaskets on Monday. Because I cleaned all the oil up the car did cool down a little bit but this is what I got:

Cylinder 1 260psi
Cylinder 2 255psi
Cylinder 3 253psi
Cylinder 4 255psi

Cylinder 1 had the most oil in the spark plug hole and some got into the combustion chamber which may explain why it is a little higher than the others. To remind anyone that hasn't read through this thread I have installed 0.25 oversize JDM ITR pistions with my stock Ls head. I have been thinking a lot more about putting the b16 head on that is sitting in my garage so I think I'm going to clean it up and start piecing together everything I need. I may just bring this thread back to life, not that it had much to begin with...
