guys seriously what are you going on about lol

[Msmith3327]

I am only guessing here as I have never built an engine but the fact that the top of piston has been sprayed painted could be the cause of all the facepalms!!!!

[DaveVader]

The mating surfaces have paint on... never a good idea.

[MiniLandy]

[minilee94]

oh right lol yhh i know my mate painted it for sum reason lol how would i clean it

[minilee94]

yeah i know i dont know why he didnt paint it with head on lol how do i get rid of the paint on the piston and off the block surface

[mini_mad69]

You could probably scrape it off with a sharp blade, or a soft wire brush on the pistons.

The only way i'd build that engine up after that is to strip it down and have the block acid dipped.

The paint has gone on everything it shouldn't and has also gone into the oil ways of the block. So you'll end up with specs of paint going around your engine with the oil!

this is true, if i was you i would take the advice, strip the engine down to the bare block and have it dipped, if you end up with paint swishing round your engine it can take bearings out (believe me, ive seen it done on my mates 1330)

prob worth having the block skimmed possibly whilst its stripped down, but its upto to you

oh right okay cheers mate il give them a go cheers
