compression check

[james1986fox]

I did a compressioden check on all the cylinders in my marauder and all of them read 180 psi besides cylider 1 which read 200 psi. Are these numbers ok?

being that all the numbers are so close id say your fine, how ever i dont know what the specs are

[james1986fox]

Anybody else got any info on this

id say your good...if you did a dry check and all were between 170-220 your fine. 20 psi isnt a huge change it you put a few drops of oil in the cylinders and did the test again they will all probably be even closer.

im just trying to get this lean code on bank 1 figured out my cylinder one spark plug keeps fouling out looks to be wet i dont know whether its oil or gas but the car definately feels like its only running on 7 cylinders my fastest time down the quarter mile was 15.48 with cai, 4.10s, and tune so somethings wrong.

That is about right, I would also recomend a cylinder leak down test.
