Anybody got any advice on doing the exhaust manifold gasket on a 20R?I ordered the gasket and set of studs/nuts from LC.I was lazy and paid a Big O to do this about two years ago. Well a small leak started a while back. and then on Sunday while coming back from Tahoe, I threw a fan/alternator belt and truck got hot. Temp didn't peg out but got into the red before I noticed. Anyway, the small leak is now a big leak and needs to be addressed.....hopefully head is still true. The guy that did it two years back replaced a broken stud with a Grade 8/Class 10.9 bolt (so he said); so at the very least this one should get a new stud.Should I try and replace all the studs with new? Do you guys red locktite the stud into the head? Antiseeze on the manifold/nut side? Any helpful tricks on getting a stud out....will a heat gut get hot enough to help or do you need a torch?.....I know you don't want to get that aluminum too hot.Also, going to try and rebuild the old carb and retap thermostat housing bolt threads while the breather is off.....I've been too lazy for far too long for a DD. Thanks in advance and Happy New Year guys!
This has already been discussed... search for the recent thread!!Gnarls.
...I'm thinking someone just drilled and tapped the stock holes deeper here in an attempt to avoid inserts/use what they had on hand, just guessing.
