bad day engine scrap need advise

hi all well the day came when i opened my agu to fit rods and quess what was lurking underneath. brought engine of ebay from a mk4 golf runner. fitted in my mk1 and it ran fine . ive been told the cambelt had snapped on the engine in its life and some one has just put a head on it

piston 2



piston 3




piston 4





also cylinder bore 2 and 3 have a mark on them it smooth

cylinder bore 2



cylinder bore 3





had a machine shop guy come yesterday and said he would hone bores and i was going to get some piston and rings. then today im cleaning the sump and guess whats in there? the oil squirter from clyinder 1 snapped. im done with this block so i got a few questions . i can get hold of a apu passat block complete no marks on bores or pistons. i know i have to swap everything of the agu block onto apu i need to know can i still use my drivers 20v mount or do i have to use the orignal mk1 mount? also i got some forged pistons with 20mm wrist pins will my racing bearings be ok to use on the apu engine?

wounded  :tlc:

ouch!

lol thats what i fought

new engine sourced

I'd check peter but i'm sure its only the agu that use 20mm pins i could be wrong but i though other engine codes were 19mm.

well machine guy came today gave my block a hone and he said its all ok no cracks. so i decided to use the block. picked up a apu passat block today took piston out and oil squirters all match.and in good condition. got some new rings aswell and the head is being stripped cleaned new valve guides and skimmed so all looks good hopefully lol (see my wallet in picure 3 yeh its light now lol )

piston in apu are 20mm wrist pins
