Head Gasket Cleaning Help.........
What is the best way to clean the remaining material off my 97 LS1 block ?
I tried plastic putty knives, razor blades and acetone. Is this the graphite ? It comes off like pencil lead like.
1 hour later and the drivers side of block is not 1/2 done !! I don't want to scrape into the block with the razor either. I guess, steel blockes are alot easier.......
THANKS

Check AutoZone or that type of store for gasket remover. That stuff works pretty good but watch out, it will burn your hands up! Don't spray it on anything but the gaskets, I think it is about the same thing as industrial strength paint stripper!
For scraping I like using good sharp razor blades myself. Even if the gasket remover works you will still need to do some scraping. The key to cleaning aluminum with razor blades is never turn the blade over. As you start to scrape the end of the blade will bend up, when flipped over it won't scrape as good and will scratch the metal. I always mark the blade and keep the mark up while scraping. Expect to use 4-6 blades per side on a LSx engine that had GM non-MLS gaskets.

Believe it or not, I used a bamboo chopstick with the edge filed down to a chisel. It will not scratch the aluminum and works pretty good. This is the most time consuming part of the job, and your time and effort will pay off with no leaks. In my opinion, don't rush the job with anything that puts the block at risk of a scratch, especially if you are using Cometics.

I worked on it a little more. It does take a long time to get it done !!
Some of the grey,fine material coming off the block looks like graphite w/ a sheen.
Time to do some more.........
Thanks
