- This question is related to an MGA engine so if you aren't interested please press DELETE now. I did a compression test on the MGA engine in my Elva and got the following results (reading from cylind

- Hi Michael, The idea of the wet test is to identify whether the leakage is through the valves or the rings. The fact that there is very little improvement in the relative compressions would definitel

- Hi Michael, Yes - I think it would tell you much more. It will also tell you where the leakage is. On a serious race engine I would consider anything greater than 5% leakage to be excessive. Regards,

- I would think that the increase due to oil would point to rings rather than valves. A leak down test should help pinpoint the cause of low compression. If it is an intake valve you will hear a faint

- I have always considered a compression test to be crude at best at pinpointing problems. The readings given tend to make me also look at piston to wall clearance on the motor. Off the top of my head,
