RE: What compression level is bad?



I am aware of this (re-read the message :))
the question is , for the person looking for the information

what is the normal compression and compression differential for a 1.8L 16v
Engine.

Anyone out there got the answer, my knowledge is really limited to 8v at
this point.

those are good #s for 8v.  the 8v motor is 8.5:1
where a 1.8 16v is 10:1.
