Coolant over flowing

[JET]

I have a metal head gasketAnd your point? Was your block and deck both machined flat?

Usually when a DSM HG goes, it blows between a cylinder and water channel. I haven't seen one go near an oil galley, and I have blown quite a few over the years! That is why you usually don't seen anything funny in the coolant, you just end up blowing it out.

But wouldnt I just be looseing coolant and smoking? I do smoke a little at WOT in first gear but I was told that its just because of the breaking in of the rings and stuff. My block(800 miles ago) was decked last year when I rebuilt it and the head when I got it machined(600 miles ago). Have a mitsu metal HG copper sprayed and ARPs.

I would start by renting a coolant system pressure tester from a parts store. Check your cap and pressurize the radiator and see if they both pass. If the cap is bad replace it, if the radiator/coolant system doesnt hold then move on to a leak down tester and keep looking.

I didnt realize people copper sprayed metal head gaskets. I thought that was only done with the stock composite one. If so I just learned something new.

Did you retorque the head studs after a few heat cycles? How long does it take to start blowing out coolant? Try babying it the next time you take it out and see if it takes the same amount of time if you are nice to it.

The radiator cap is the first to try, after that start checking for a bad HG.

Got new cap and beat on the car a bit and no coolant overflow.

You are lucky if that fixed the problem. I have neer been that lucky.

Woohoo! nice work! Gotta love the cheap fix.

Heck yah! When I went to the store and put the new one on it felt totally different then the other one. It took a little force to "clip" it on where the old one was easy. Now I just gotta fix all the other problems

Just be happy this didn't happen to you. some serous detination blew the fire rings in the head hasket. notice there oval now instead of round, and blown between the clyinders. the stock head gasket saved me though no damage to the pistons cylinder or head.
