coolant creeping up head stud (external stud)
noticed it at the track.. at one of the head studs on the water jacket side of the head of the stud is outside the head. its only when its warm. it was petering out. at 1st i thought i lifted a head but it was only comming out of that 1 stud, and none out arount the head gasket.

Heck yeah, it's going to be a problem. The cooling system is meant to be sealed tight. I would be concerned that if one was leaking, others will too (and inside the valve cover). Cooling passages can get clogged by RTV. I would not use if for sealing threads. A non-hardening sealer should be used.

As I always say when this comes up, USE #2 SEALANT, only use this stuff. I along with quite a few others have never had a problem using it on head studs, while others use the arp sealant, other thread sealants, rtv, etc, etc and it all leaks.

The permatex #2 seems very "slick" for some wierd reason and I would be worried about something coming loose. I noticed this once when I used it on rocker studs.
