Hey All

I have a 95 LT1 on my engine stand that im swapping in to my firebird over the coming winter. I did some compression testing tonight. The engine has sat for over a year. First run i did dry
1 - 120 2 - 150
3 - 160 4 - 120
5 - 125 6 - 140
7 - 150 8 - 120

After the first run i added a cap full of oil to each cylinder and did it again.

1 - 200 2 - 215
3 - 195 4 - 195
5 - 200 6 - 200
7 - 205 8 - 200

I was concerned at first as i didn't see much oil pressure, I did loop the oil cooler lines together prior to starting. When i started the second round of testing i started to get oil on the lifters and rockers. I also put a mechanical oil gauge in the block, pressure was around 20-25 while cranking the engine.

No intake or exhaust manifold, cranking with a starter, not by hand.

I have never done this before, is there anything I missed? I watched a few videos and read through a few threads here.Do these numbers look ok? I was considering doing it again in the morning after letting it sit for the night to see if the "dry" numbers are more consistent.

 

Looks excellent. Run it.
