So a proper leak down test and compression test isnt going to happen..

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Long story short i have a 2002 996 with a blown engine and have a another that is on a engine stand and need to test it to see if has a problem. I know that it is recommended that you preform this test warm but that is not a option. I will also be doing a compression test.. As i have no history on the engine and it has a heavy intermix.... like so heavy that i dont think it can be a cracked head...also the crank case didn't intermix.. I tested the oil cooler and it didn't leak when tested with pressure on the coolant side.(tested at 60 psi) but i tested the oil side with 90 psi it leaked to the coolant side.. also when i removed the cooler from the engine the rear coolant port the large one closest the flywheel was full of non mixed oil and underneath it was intermixed oil.. So before i change the oil cooler and install engine i would like to verify that the engine doesn't have a bigger problem.. or before i tear into it and rebuild a top-end for no reason.. So the question is will a cracked head show up on a cold compression test and leak down test? As compared to the other cylinders? Thanx for any input if you have preformed these tests before Marv,

POST 2Original post

Heads must be pressure tested at operating temp to reveal all cracks

POST 3 / ORIGINAL POSTEROriginal post

The engine right now is on a engine stand and i stripped it down to a long block... So a proper leak down test and compression test isnt going to happen.. Thanx for the reply....

These guys just fixed my cracked head. Some cracks have to be heated to find. Hoffman Automotive Machine Inc. 1880 Commerce Rd. Suite 211 Athens, GA 30607 [phone removed]
