2G Cylinder 1 low compression.

[cammyd21]

I have a 97 eagle talon and I'm getting low compression in cylinder 1 ( 100 psi) and 195-200 in the other 3 cylinders. I have oil in cylinder 3 and the turbo inlet. Any ideas on what could be causing this? Appreciate any help

I would do a leak down test, compression test doesn’t tell you much as to why. Perform a leak down test and it will tell you where the problem is on the specific cylinder you are concerned about. I would say 10-15% air loss is acceptable on a motor with many miles. Then you will know the answer to your question of why I’m low on compression. Depending on the results some oil in the compressor housing is the least of your worries. Good luck
