i got 160 in three cylinders and 170 in another, g13bb, is it still pretty good ? trying to work out if the valve stem seals and leaks are my only oil eating issue.

mine has around 195-200 in all cylinders so that may be a little low but i dont know about the rest

[unique_seek]

around 200 is ruffly 10:1 compresion,you probably have 8.5:1 or around there,I dont htink there is anything to worry about?

was the test done on a cold or hot engine,wet or dry test?

All good there Sam nothing to worry about all within 10% that is what lula's has been on since we got it.

as Josh said doing it wet or dry can make up the differance.

DRY = Cranking the motor only Hot
Wet= Cranking it with throttle down. Hot

Same can be done with cold engine = Lower reading.

Also to check rings are Ok place a squirt of oil in the plug hole and test if it rises alot the rings may need attention Eg : 120PSI Dry Oil added 170 PSI

well it was cold and dry, so looks like it is pretty good still

did not want to do a timing belt if i was going to have to pull it apart later
