So I think I blew my headgasket

Postby Killtodie » Sat Mar 21, 2015 3:52 pm

Was driving last night, on the highway I put my foot down to pass, blew a HUGE cloud of smoke out the rear end, boost cut, and then the car struggled to drive under load. Kept stalling. Got it home eventually.

Heard some misfires, car was running super rich, blew fireballs out the exhaust a few times.
Checked for any vacuum leaks, or loose components. Nothing.

I will be pulling the plugs, and checking compression, and timing. Kinda feels like the timing is way off. Maybe I blew I headgasket, but it not misfiring much, sometimes it drives okay, sometimes it struggles under load.

I'll know later when I start pulling.

How did you check for vac leaks? I'd do a boost leak test to make sure things like the intake gaskets are okay.

Listened for leaks with a stethoscope.

Well, good news.

What I thought was a cracked manifold turned out to be a ruptured silicon coupler. So that needs to be replaced, and was the cause of my problem.

And there was a few loose exhaust bolts that left some trails which I thought was the cracked mani.

Just need a new coupler now.
