on a LS motor.

#1=165
#2=150
#3=150
#4=140

would it be safe to boost on this compression? what could cause this?

 

this was on a cold motor....

 

well maybe you should warm up your motor then do it

go drive ur car around for a bit and then pull the plugs and do it again... u should higher #'s IMO. somewhere around the 180's........... i did mine last week and hit 200-205 on all 4....

 

if it's warm, wouldn't the only difference be that the numbers are higher but still out of wack?

is that a maybe/maybe not?

 

all motors are different. no motor is totally alike.....so yea, maybe.......maybe not

 

Try adding a little bit of oil, if your compression number raise drastically your rings are in bad shape.
