Cold Compression Test

[gsXmitsu]

I need to do a compression test but cant warm the car bescause there is no turbo, it blew and 1 of the feed lines broke. anyway what should cold numbers be? I would idle the car to get it warm, but oil will go everywhere. thanks for the help

You still might get oil everywhere. When you turn the car over, the pump moves too.

Engine needs to be warm for a true test. Do stuff right, or not at all. Even if you try it, all you need to do is make sure they are all alike, and none of them are way out of line from the others.

more oil will come out frunnin for 5 min than just turnin it over for 10 secs. if i had a turbo and a line id have no problem running it to get full temp

Need to fix the feed line.

Reinstall busted turbo or replace with new or rebuilt one etc... and heat motor up to accurate results.

You cannot do a cold test as the motor is not warm and the rings are not sealed, makes comp test useless.
