studs holding on headers, had block and heads tested for cracks at build 2 years ago and all checked out good so I don't think its a crack, re-used head bolts so they should be correct length. they are torqued to 70 lbs could it be coming thru gasket some how? How much torque could I put on them?



Are the studs the originals or did you replace them ? I think it's coming from a stud , gravity is a funny thing.

But if you think it's coming out of that hole pull the bolt , if it's coming up that hole it will be full of antifreeze.

Rereading this , is it under the valve cover or under the exh. manifold ?
