I put this in my build thread as well but i know some of you dont read those so i'm posting it here as well. If you mods dont like feel free to delete.

Weekend before last i brought the car to a shop in kingston NH to get finished up and tuned.
Today i made a trip up to drop of a couple parts and was met by some bad news....
They did a compression and leakdown test.
Cylinder Compression Leakdown
#1 180psi 10%
#2 180psi 10%
#3 180psi 10%
#4 150psi 50%
#5 170psi 10%
#6 180psi 10%



So they asked if i want to continue to move forward, which i am.
Don't have the money to have them fix it so i figure i'll just have them get it running and get the AEM tuned so i can drive it.

I'm hoping theres just a speck of something keeping the valve from sealing. He checked it with a boroscope but couldnt really see much. He thinks the valve is slightly bent causing the bad leakdown test, but assuming that the spring is pulling the valve shut more during the compression keeping the compression somewhat reasonable.

Being a non interference motor how would a valve even get bent?

Opinions?
Advice?
Suggestions?
