Blown Headgasket....Perfect Compression? (smokin ZC)
I swapped a DOHC ZC into my car and it smokes. I have no clue whats burning as I cant drive it around the streets to see which liquid is getting low as it is not inspected. The smoke is white and there is plenty of it, but I DONT seem to be loosing coolant. I do have quite a bit of condensation build up at the exhaust almost instantly once I start my car. My oil is not contaminated and the coolant isnt either. I checked my compression and it came out to 190-195 PSI accross all 4 cylinders. Is it possible to have a blown / slightly leaking headgasket and yet the compression test is still fine? Another dumb question...but if I were running super rich causing cylinder wash to occur causing me to burn oil...the smoke would have a bluish tint to it correct? Im gonna get a leakdown test done sometime this week......

If its steam and/or water condensation its a head gasket.

its possible that its running really rich but since you just swapped it did you replace the rings? that could be your problem especially if you didnt deglaze your cylinders just a thought though

Did you do a dry and wet test? Do it again and put a teaspoon of oil into the cylinder. If it gets more compression you can test to see if it is the rings or not because the oil will make up for the compression the rings aren't providing.
