i have the block scraped and the head scraped waiting for my new ARP studs.
the top of the cylinders need to be cleaned up but unsure of how, tried to scrape - only chewed up razors, used scotch-brite - no effect. open for ideas.

top of the cylinders? you mean top of the pistons? anyways... ive always had good luck with simple green and anything that resembles or is close to a toothbrush.

yeah, do you mean the pistons or the deck?

the outer deckhas been scraped, but not the cylinder "tops". its a d15b2 see crappy picture below.

oh yea, makes sense now. i have always used (i think its a felt pad??) and put a little bit of clean oil on it and its always came right off.

 

[sql_civic]

800 or 1000 grit sandpaper with some WD-40.

 

[Hellhatch]

Scotchbrite pad.

Right-angle die grinder and aluminum polishing "wizzer" pads.
