coolant leaking out the exhaust, replace head gaskets?

90 deg does not have to be exact. 88 or 95 will not hurt. These are torque stretch bolts. When you see a turn after torque in the manual, I am sure it mentions that, make sure you use new bolts. This is usually the case on aluminum heads. Reuse an old bolt and it can break.

the tool your looking for is a degree guage, on the rockers, you torque them to some where around 40pounds and then 60 degrees, there pretty cheep. i got one at sears for 30 bucks. hope this helps! make sure you get the right specks for your motor, i think there is a set of updated specks for most years!

about the intake gaskets, if there broaken that's probably the problem. the only way to see is to look at the coolent trace markes in the intake it's self. you'll beable to tell, it will be obvious.

I was going to get new head bolts.

I was looking at a head gasket set at pickproparts.com but I am not sure what is included in it. I know I need egr gaskets, head gaskets, intake gaskets, exhaust manifold gaskets, valve cover gaskets, and a distrib plug oring???. Can anyone think of anything else?

there is a coolent bypass pipe that has an O-ring, also there is a rectangular coolent bypass under the intake, which should come with the intake gaskets. one other thing you might want to replace the t-state while your in there, i don't remember if it has a rubber type gasket of paper, but it's a good time to be inthere and replace it! you'll also need a small tube of RTV or slycone and some cans of brake cleaner. the gaskets seal better if you spray both serfarce with it! that's all i can think of!

I thought about getting a new thermostat, should I get the 180 degree?

Also what parts will require rtv sealer?

The intake and heads and exhaust do not require sealer do they?

Thanks.

If you get a head gasket KIT, it will include everything you need except the bolts.

ok bszopi, I was looking at the kit, for 170ish. Thanks.

How about the sealer and thermo anyone?

[jeremy96gase]

no sealer, just gaskets.

[kill_them_all]

Jeremy, Thanks.

Anyone know if I have a better advantage on anything going with a 180 degree thermo?

Thanks.

i thinks the lower manifold requires it and there are 2 indentation in the valve covers that need RTV of sylcone. 180 all that it would do is lower the temp of th coolent, helping with a knock issue. it also might lower your gass milage, but now would be the time to do it!

[ProjectMM]

ps you also need to seal the lower manifold bolts with some thread/teflon pipe sealer! the go through coolent passages!
