Yea, it was coming out of the exhaust, the coolant was spilling into the combustion chamber from what the plugs indicated...

You have a blown head gasket.

Think of all the money you'll be saving on lost oil after you fix that leak while your addressing the headgasket.

Btw, will you fix the car now? You said you weren't putting anymore money into it (good one )

I am going to buy an Allen 6 socket now to start taking the intake off and then tomorrow I'll start on the head, gonna take this opportunity to fix the stripped exhaust manifold studs I have and change the exhaust manifold gasket, since I know I had exhaust leaks there, I should have it together by next Friday, I'll work on it after work in the evenings when it's cool, gonna also change the venturi lines and get rid of some hoses and check vacuum lines down there as well, gonna go buy a Wide Fire headgasket, I think i'm gonna change the lifters too (cups)

Sorry about that...

When shopping for allen sockets, keep in mind that you need a long (or skinny) socket to get the inside cam tower bolts off (i.e. a socket that will fit in the holes in the tower, or a bit long enough to reach into the tower).

See Luis that's what i mean you never listen, why would you buy a widefire hg? the most important issue is to find out why your initial hg was blown, 2nd buy a proper maf or a system with a piggy back to adjust your a/f ratio and 3rd get a mls head gasket from vitesse. Screw the wide fire unless you have o-ringed your head it is useless.

My head was O ringed and I supposedly have a Wide fire in there, the reason it blew was not because of the 15 psi I am runnig, but because it was overheating, both fans weren't working when I popped the hood open and I had just done 150 mph on the Palmetto Expressway right before it started misfiring and blowing coolant out the tailpipe...

Okay you know, my lips are seal, but I am willing to bet your blown hg has do to with your setup.

Btw, I don't think your car would overheat at that speed even if the fans weren't working there is enough air going through to keep the engine cool.

Check the head for warping. A straight edge and a feeler gauge will do it.

If you get a head gasket kit, it will include all the required gaskets, instead of going for the wide fire and exhaust gaskets.

Get a tap and die kit, go over all the threads of the bolts, studs and holes.

Thanks, I saw the kit, 944online has it for $139, the Wide Fire kit for $199, I am planning on fixing the exhaust leaks on my manifold and a broken/stripped stud, replacing them all while I'm at it...
