Cleaning A Turbo

[elad_33]

Hey guys just picked myself up a good condition used R33 Series II turbo

I've cleaned the coolant galleries and flushed the oil gallery

Just wondering if theres any safe way of cleaning the compressor fins and turbine fins ? I was thinking of spraying the exhaust fins with carby cleaner/brake cleaner but I was unsure of this.

Also one more question I put oil into the top oil hole in the turbo and filled it and it didnt drain out the bottom ? does that mean there is a blockage or do they need the oil pressure to squeeze the oil through ?

Would appreciate any advise.

Thanks

i wouldn't use anything that leaves grit or residue, as this will be entering your engine. i would think electrical contact cleaner would be safe.

Yeah thats what I was thinking....Something like brake cleaner would be good because it dries pretty quickly but also i dont know what reaction (if any) it would have on the compressor fins since they are ceramic.

Do you think it would be ok to use brake cleaner on all of the turbo fins etc ?

metho/turps

not as harsh as the other chemicals listed - and still flash fast

the compressor wheel is steel, unless its from a very late series 2 then it maybe nylon/plastic. The exhaust wheel is ceramic.

I wouldnt be too worried about the exhaust side, the first decent rev will clean most of the junk out. If you want to do a good job on the compressor side, just undo the compressor cover. Theres 2 brackets on the back with a few bolts holding it in. Its very easy to pull off, that way you will have full access to the turbine and inside the cover itself. I would just use some degresser, since it should only have a bit of oil residue in there anyway and will come off easily with a rag.

Just make sure the cover is in the same postion when you tighten the bolts/brackets back up

But is it safe to take off the front housing ? are they specifically put on or something, or can they just be taken on and off as long as they're facing the right way when it goes back on ?

I pulled my HKS2530 off tonight as im changing exhaust manifold studs and it looks like it needs some tlc.

Ive done a search and this is the only thread ive found about cleaning a turbo and I think it is ok to take the front cover off a turbo just make sure it goes back on the same way you took it off. like put 2 dots on either side one on core and one on cover then when your putting the cover back on just line the dots back up

Im just not sure about using degreaser? could it hurt the seal behind it? im thinking of using a rag soaked in degreaser and an old toothbrush so theres less chance of it hitting the seal.

Any ideas ?
