Well decided to take engine out yesterday and have partly stripped it to the point that the sumps off intakes off so looks like a bare complete engine ,anyway I've noticed small prices of copper in the sump so im thinking a big end bearing maybe , also I've noticed abit of play in the rear cylinder big end I did this by rotating the crank back and forth , so What's to cause this ? Oil pressure ? never had an oil pressure light on...

Honestly I didn't check the deck height or allow for any head skimage , but have been changing head gaskets for 4 years now on more regular vehicles Renault Audi Peugeot Citroen etc.. And have never had a problem with that sort of thing, it did run perfect for 500 ish miles not knock or overheating , I'm hopefully taking it out over Christmas and will keep you posted , it didn't know wheather it's that I've not ran it in properly :(

hi all this is my first post here so bare with me... ive got a 2002 wrx impreza brought it for £700 with head gasket gone and crank knocking. took the engine out stripped it all down , sent the heads to get skimmed ,( i could see where gasket had givin up) removed the crankshaft and sent away to get reground to 0.25 brought new mains and big ends full engine gasket set no4 piston had started to melt slightly brought a new piston and rod re glazed the bores and everything felt and looked good stripped oil pump and all looked good built my engine back up fitted into car and whaeyeyeye so after 500 miles of driving sensibly, (no rpm over 4k and graduated acceleration)I dropped the oil out and filled up with some new I checked the oil that came out and it had no contaminants init. brilliant !! so with 500 miles on the clock and new oil I thought id give it a little more acceleration than normal maybe 5k and after 20 minuets of driving it started to over heat and started knocking !!! so its sat on my drive waiting for a strip down... anyone have any ideas ?? pleaseee
