#136240, "compression numbers"


          

So, I finally got a chance to do a compression test today, starting from the left as if you were looking at the block from the front of the car: 180,185,195,195.

I want to note that I am running JE 8:8:1 low comp pistons and Multi-steeled head gasket. Just wandering if this is okay?!

Thanks.

Seems good to me, honestly would expect a little higher if it was a fresh rebuild, but nothing wrong with them.

Hmm, maybe because I did the test cold and I have around 3k on the motor so far..

Stop over analyzing it. 3K miles is not going to change anything unless you are running with WD40 instead of 30 weight.
