Headgasket?
Headgasket?
OK so started up my car this morning and light grey smoke started tumbling out of my exhaust. I pulled my dipstick and noticed a TINY bit of milk. Haven't dropped any coolant from my tank and pulled valvecover off and things look ok. I did a compression test and reads as follows.
142psi 125psi 125psi 121psi
Does this sound like a bad headgasket or possibly stretching my stock head studs? I'm making close to 300hp which i heard when you start having problems with the head studs.
Here's a video of it as well.

apparently i need to redo the test. Someone corrected me on how to do it. mods are as follows.
Stage 2, 2.9 pulley, 3in full exhaust, alcohol injection, K&N typhoon, step colder plugs, trifecta tuned. i'm probably not at 300 on the engine but figured it might be getting close?

you are probably close to 300 crank. That still shouldn't be what's causing it. Re-do the compression test and post them up again. AT this point though, I'm going to agree with you that it's probably the headgasket. I doubt your head bolts are stretched though as you are not pushing enough boost to lift the head. Might be a bad ring. Could be a cracked head.
Just re-do the compression test and post up the numbers.

ok So i retested and from what you said i'm still low. 165/165/165/150
And i'm now sure why but this time for some reason i pulled the first plug and it had some clear liquid/water on the top of the piston i could see..... but i'm not running just water.... i'm really confused and thinking the head needs to come off now. Is pulling the head off pretty easy? I have a build book on it's way but would like to get started if possible and maybe get some head upgrades while i'm digging in.
