i have a 97 Z24 and i'm getting the head p&p, when i removed the cylinder head, cylinder number 3 had oil on top of the piston so i cleaned it off and all of the pistons have corrosion on them, is there away to clean this and also is there a tool i can use to clean block surface where the head gasket goes?

razor blades.. a window scraper works well.

carb spray is your friend. lots of carb spray!

also, a block with light sandpaper on it as well, just make DAMN sure you get all the gasket cleaned off first, and at the end just to get all the shavings and chunks of crap all off.

I just did this to mine the other day.. Brake cleaner is your friend.. I couldnt get ALL of it off but most of it I did..

jeas man im surprised u had any atal! 900 miles!

i used WD40 and light sandpaper, then dryed it off real good. The top of the pistons looked real nice. I wish i had took pics when i did a valve job on my head, also the machine shop i took it too didnt port n polish.


GMR has got nothing on this

cool i was wondering if it was okay to use light sandpaper what grit?

Purple power degreaser works AWESOME! that combined with steel wool will clean it up nicely! (make sure to CLEAN THE WHOLE ENGINE if using steel wool)

STEEL WOOL FTW! theres your answer right there, steel wool and carb and or brake cleaner spray

can steel wool be bought at AZ or any other local auto parts store?

yep, hell a grocery store might have it... just dont get the one with the soap in it!
