Has anyone done a compression test on one of these motors. I want to check mine for the wear. I think it feels like under high loads here lately i'm getting a feeling from the engine like i'm getting blow by?

 

I believe the specs is suppose to be 150 or better.

 

150 seems to be a little low for 9:1 compression. I remember on my 2g eclipse GSX that the compression was in the 170's across the board even with over 100k on the odometer. Considering how new the evo X is, I would say the compression numbers should still be good.


To the OP, what makes you think you're getting blowby? Burning any oil?

 

Go ahead, might not be a bad idea to star getting some down and see what they do.
