Title: Compression test
Post by: Elite Pete on 29 January 2010, 10:31:34

What psi should a healthy 2.0 4 pot give.

TIA  ;)

Never tested this engine but as a rule I'd say 150-200 PSI.

Teaching granny to suck eggs of course but variation between cylinders is the biggest clue that something's up. :y

Thanks Kevin. Just wanted confirmation. I've just done one and got readings of 90, 80, 130 and 80. Think the biggest give away was the no oil on the dipstick even though it had been standing 2 days :(

174-218 psi (12-15 bar)
Allowable difference between cylinders = 15 psi (1 bar)
