Well I pulled these numbers..

207-195-185-190


Should I be worried about anything or what, I have been kicking the thought of a rebuild in the back of my head.

looks good slight variance not to worry about. possible valve adjustment need.

puts rebuild ideas away for a little while.

what are perfect numbers for gsr??

Evs-One

could be 80 psi across all 4 on one gauge, and 250 across all 4 on another gauge.


You really shouldn't judge an engine on the actual numbers, but rather the consistancy......I'd do a proper valve adjustment and redo the test. I'm sure the numbers will change slightly

good numbers tho

megotvtec

are they useally not the same for each cylinder though??

Evs-One

a healthy engine will be within 10% of each other. Say your highest reading is 200 psi and your lowest is 180 psi.....thats a 10% difference...which is fine. If you had one cylinder down to 120 psi...then you have something to look into

cool thanks! im pretty sure i cracked one of my pistons last friday so im gonna do a compression test on monday and see what it says.

also, the testing technique used, could change the peak output #'s. Like # of cranks, WOT or not...

just did compression/leak down test.
cylinder#1. 130
cylinder#2. 140
cylinder#3. 120
cylinder#4. 40

are those ok numbers for the first 3??
also cylinder#2 tops out at 140 but when i shut car off it leaks down to 110. does that mean the piston rings arent sealed tight around the cylinder wall? or is it a valve not closing all the way? i just tightened my valvesprings last week. so it shouldnt be that

i got 210 across on my gsr motor
