so i need to get the old left over gunky ---- of the block what did you guys use ive tryed scraping it off and light sand paper and nothing seems to be working to great lmk thanks

 

They make these scuff pads that look like a little disk of scotch brite that you can chuck up into a drill. Forget what they're called...

 

any gasket resurfacing kit will work with either power or air tools needed to fit the bits. Or a mill

 

use an angle grinder and some elbow grease. (thats my best al gore impersonation)

 

Wire wheel FTW.

 

I bought some gasket remover spray at napa and got some of those 3m abrasive pads. They work beautifully.

 

flip the block upside down and drag it with your car for 1 block on a smooth road

 

or 40 grit sand paper

 

damn that worked great !!! why the hell didnt i think of that

 

i used gasket remover spray and other cleaners i found layin around, and a plastic scraper/3m pad. didnt work that fast but it worked.

my friend used engine brite on his and it cleaned the pistons tops all good too he said , im not sure how safe this is but i might try it next time.
