its a long story but i`ll try and keep it short

basically i found gliiter in my oil so i knew something was up, no knocking though.oh and the oil pressure at warm idle was a bit low - 2 bar
more out of curiosity than anything else ive stripped the block, ..all the bearings seem ok except for the thrust bearing which has serious wear to the sides, right down to the copper. ive checked for end float ,crank seems tight no movement at all.
what idid find to my horror was 0.5 on the bearings so i presume the crank has had a regrind.

what do you think had caused the wear on the thrust bearing, the only thing i can think of is when the crank was ground they didnt grind the sides where the sides of the thrust bearing contacts therefore it would have been very tight fitting, i presume the 0.5 also means the sides of the thrust bearing are also 0.5 thicker.
apart from that the crank is in good nick.

2 bar at warm idle is ok pressure mate,it wouldn't worry me any at that pressure but obviously metal bits in my oil would lol.

some say 2 bar is ok but my old 70k motor was 3 bar, it would have just gone pop sooner or later so i stripped it , it was going to have an 18g fitted so i dont think it would have lasted long

I agree mate with extra power it wouldn't have liked that much lol,and by the sounds of it,it was a good idea.
It could be remains of the grinding process in your oil mate as ive heard it is almost impossible to get it out of a subaru crank when ground?.

i think its the centre thrust bearing, looks fcuked.

love nice surprises like seeing 0.5 on the bearings. it was meant to be a rear thrust bearing crank, had once again

yeah see what you mean about the regrind, is that why youre not meant to grind them

It is rare in this day and age to get what's advertised,so many scammer's about now which sucks aye?
Which is exactly why i forged my own motor so i know what ive got.

Trouble is most parts are worth a good few quid[if genuine] so people see a good chance to make an easy buck when they have something that can be palmed off as the real thing and usually succeed which is the worst part.

its part of the problem being a boxer engine.i didnt want to split it, ive learned (kind of)

i bought it as forged and it did have forged pistons plus receipts so i thought it would have had the rest.
