i assembled the block they did the heads. when i ringed the pistons the rings were alittle tight but they spun and moved i didnt think anything of it..... i fubared this one. but the rings and pistons came together so i just assumed they were right. i need 1.5mm rings not 1.9...... oh well live and learn. ill check next time.
in the lands. a mix of what looks like teflon off the side of the pistons, and very fine metal shavings from the cylider walls. i do not think i cleaned the block well enough before assembly. all the bearings look great, lucky me. so as to not make the same mistake again i will scrub and wipe the walls down better this time. idk what to do about the teflon coating however. hopefully it wont spur any more issues. ill post pics later today.
