ok folks, I just had a compression test done on my 89 CRX DX. There was some oil on the number 2 spark plug when we romved it for the test. Anyways, the guage readings are as follows:
Cyl 1- 235 Psi
Cyl 2- 245 Psi
Cyl 3- 230 Psi
Cyl 4- 235 Psi
Can you folks tell me if these values are good, bad, average, within factory spec??? I beleive the oil on plug #2 indicates a worn valve seal. the car has 218,000 miles on it.

it could be because with that much miles on it, coudl have alot of carbon build up and have high compression

There was oil in the car if that's what you're talking about. Will high compression cause any problems? Should I think about doing some major maintenence on the engine?
