94 Blazer Gasket Issues

[yesimsteve]

So I was removing my alternator and well the ring holding the bolt broke:



Any suggestions on how to fix this?? could I use epoxy or something like that? Thanks

You could take and have it welded. I doubt expoy would hold for long.

You could try and get it welded or check out your local junk yard and see if you can pickup a whole new bracket and just replace it.

I have my left exhaust manifold removed.. but its suck inside the car. There is a circular piece just above the exhaust manifold but below the valve covers that is blocking me from removing it. It had a white electrical connection attached to it that I removed by squeezing and pulling it off. It kinda looks like a big spark plug.

do I need to remove this?? and how?

Yes you need to remove it. Its a Temp. Sensor. I can't remember what size deep well socket it is, but when you remove it. You will have Anti-Freeze running out.

Putting it back together should be easier as long as you have bag / tag your bolts and wiring that you remove. Sounds like your coming along just fine. Hang in there not to much futher.

ok so i just removed the valve covers and they are caked with yellow crap! it looks like cheesecake in there.. im assuming thats bad. What does that mean?

Secondly, what can I use to clean all these parts.. lacquer thinner? what do you guys use? thanks.

Your Cheesecake is a combination of antifreeze/water and oil. You can clean it with engine cleaning solvent. I wouldn’t use Lacquer Thinner. It will eat up your valve guides, and that’s not a good thing.

Can an engine cleaning solvent be used anywhere in a engine?? Also I was told to clean the gasket surfaces with acetone or laquer thinner..

I just want everything clean when i put it back together.

Engine solvent can be applied anywhere in the engine. It doesn't take off paint like acetone & lacquer thinner does. Just make sure that when your done cleaning the heads your shoot it down with water. If the heads are going to sit for a day or so. It would be a good idea to pour oil over the springs, rockers, & valve guides. This will keep it from rusting. Cleaning of the gasket surface, I would use brake lean. It doesn't leave any residue. That will give a better seal on your gaskets.

So this bolt is now offically stripped.. its edges were very rounded to begin with then i used an adjustable wrench on it.. bad idea. Any tricks on how to remove it? Its in a pretty tight spot.

Ok now in order to get to the right head gasket I need to remove the air conditioning compressor.. It says the system is under high pressure and I should discharge it.. can I do this myself?

There isnt anyway to keep the A/C charged while I get to the heads?

Yoiu can leave the air cond freon lines/hoses on the air cond compresser.
Just unbolt compresser from its mounting bracket and lay it over to the side.
Sometimes you can use a little wire to tie it or hold it over out of the road.
