Any high temp thread sealant should work fine!shadetree3800 said:well i was told just to dip them ends of the studs into motor then screw them into the block hand tight. but there is only one stud that is leakin and it is on the front bank of cylinders on the transmission end and it is the lower stud, the one that is not under the rocker cover. but if i'm going to put sealant on it what sealant would you recommend
I also had a head gasket leak and I even used thread sealant on the studs. I used 3 disolved GM seal tabs (3634621) and it stopped the leak. I figured I would try this before I took the head back off.shadetree3800 said:i had my block decked and my heads shaved in the rebuild process and i used INTENSE mls head gaskets and i have a coolant leak around one of the head studs. can anybody tell me how to go about fixing the leak.
No problem. The motor is apart anyway since I had a rod bolt break and I lost a rod bearing. The spare engine is getting the work done now and I will seal studs with the proper GM sealant this time.Excell said:You might be able to seal the motor with the GM tabs, but those things SUCK and muck stuff up pretty bad. They are a bad solution to the problem. (sorry Greg)
Sorry to deliver bad news.
