hi guys, im new to all this subaru stuff but i gota say wot an awsome car!!!!!! ive got a 1995 impreza import running a tdo5 20g turbo, pink injectors, z4 ecu, and a full hks pipe, thing is, im halfway through an engine rebuild and have noticed in the sump there is what looks like aluminium fillings, im a painter at ford and to me it looks like a silver metallic base coat, its not corse infact i can hardly feel it between my fingers, is this normal for a car of this age or is there sumin wrong??? please help me, cheers also, im replacing main bearings, big ends and piston rings, is there anything else i should replace while the engine is out?

 

You will get some build up after a while and its normally from worn shell bearings.

Main thing to check is that the crank has no pits or scratches on the journals where the shell bearings sit, the bores are in good shape, the oil pump isn't in kit form and the camshaft carrier caps, the head where cam sits and the cam itself are in good condition. Also check small ends, gudgeon pin and pistons for damage!

Basically anything thats meant to be nice and shiney is lol

 

Take it you engine was rattling hence rebuild?

 

Before you even begin to carry on, if those filings are off the main bearing then you need that engine cleaning out properly, ensuring that when you rebuild it, you have replaced the oil pump, modine etc, even the crank can be upgraded to a new one with better oil feed.

hi yes it was, it had new big ends put in but still rattled, so i stripped it down again, i couldnt see why sumone would go through all that n not replace mains 2???? also ive noticed in a couple of the cam journels its a little rough, not major but i can feel them with my nail, there was also a little smoke which thaught was odd, would the bearings cause this?? thanks to all of u for ur help by the way

 

Oil smoke? If so more likely to be worn piston rings causing high crankcase pressure, worn valve stem seals, damaged turbo or blocked breathers.

 

yeah like white smoke, not as bad as a blown turbo, but i was thinking rings, the bores are perfect, looks like the just been honed, i was gona do rings, just s well while its all out,

 

If the whole lots out you just as well do the whole kit n kerboodle! Rings, shells, stem seals, cam n crank seals etc!

It may seem extreme if it all "looks" good but you'll be royally pissed off if u get a leak or continuing white oil smoke and you have to pull it apart again!!

One thing you'll learn with a scoob, it don't pay to cut corners (like u said, why big ends and not mains!) and if you think you're saving money you're probably not lol. The only way to save dosh and labour time is to do it right from the beginning 

 

As Tony B has pointed out.
New oil pump is a must.
