Got what I think to be a leaking head gasket on my 1989 GMC Suburban. 5.7 L TBI Motor. Losing about a pint to a quart a week of antifreeze. Burning out the exhauset from what I belive to be the #7 cylinder. Which would be the 3rd one back on the pass side.
Tried a few different sealers, some worked better than others, but doesn't mask the problem for long. Originally I looked for a few months for a replacement vehicle and then a replacement used motor, all to no avail on my budget and patience.
So I am going to tear the top end of the motor off and replace the gaskets and hope that is the problem, and not a cracked head.
This is the set I ordered. Best price was on ebay. Shipped to me for under 45 bucks, which aint bad at all.
Also, due to the fact that the exhaust manifolds on these motors are known to warp and make it difficult to re-install wothout crossthreading bolts because of alignment issues, I decide to buy some of these tools. They are made to help with the alignment of the bolt holes when installing or to hold the shape of the manifold while it is being and is removed from the motor. Good price on these too. Love eBay.
I also need to remove the power sterring pump bracket becasue it is bolted to teh drivers side head. And that is impossible without a pulley remover tool, so I got simular to the kit in the picture. The next pic shows how it works.
let me know if you need a hand, id be glad to help
I was hoping to do this in one day because it's my daily driver, but it may take two depending how things move along. I have been beating my head against the wall trying to think of everything I will need to have on hand and ready to do this. I've done plenty of engine work before, but I never did heads or block work. Just cams and manifols and shit like that.
