loss of compression
Posted by joel (more from joel) on Thu, 9 Aug 2012 11:09:22
I posted a message a while back concerning a p0301 code. Car has 225000 and does not smoke. After doing a compression check cylinder #1 has 75psi and #2, 3 and 4 are around 125psi(these are cold measurements). I injected air into #1 spark plug hole (didn't have a leak-down tester)and heard air hissing in the crankcase. Did the same to cylinder #2 and heard very little hissing.I put some oil into the #1 cyl and I could hear it gurgling so I suspect the rings broke. The car ran well up to two weeks ago then started to shake badly at idle. Once I start accelerating it seems to run well. Changed the plugs and DIC with the same problem. Looks like I`m going to pull the head this weekend.Any common problems I should expect? Thinking of doing a rebuild.
Thanks All.
