help - 97 compression test
 

Just the the compression checked on an 87 carrera I am considering. The numbers came back as 160 on all cylinders. I found this a bit perplexing in that I thought it was highly unlikely to have the same compression on all cylinders. The mechanic that performed the PPI and compression is a highly regarded porsche specialist. What do you guys think and is 160 acceptable? I think I read that 130-175 is acceptable?

160 is just dandy. And you want them all as close as possible. Odds are they weren't all exactly 160 but close enough, so he rounded up or down a bit for simplicity. Point is, it checked out OK so don't be paranoid. If there were a problem he would have told you.

Forgot to mention, mine all checked out to almost exactly 155 on all cylinders, so it is possible.
