I've got my turbo build running now, I've tried to drive it but it won't rev up properly and it's burning oil,

I think it might be the turbo but I've taken the intercooler off and there is no oil in the inter cooler :/

What would you think the problem would be? Would there be oil in the cooler?


I don't want to pull the turbo off and find it isn't that

When is it burning oil
Ie first start up
On overrun
All the time

It could be valve stem seals
Head gasket
Pistons or rings
Turbo.. usually exhaust turbine oil seal ( as you may have already ruled out the compressor seals)
Could be something else I may have forgotten too *happy*

when its ticking over its burning oil a bit but when it comes on load it pouring out.

the fastest ive got it is about 10mph its bogging down when i try to rev it..

i dont think its the rings as the car was rebuilt before the turbo was added and it ran fine.

the only thing that has changed is adding the turbo and the head was rebuilt by turbo phil so id like to think its not the head.

there is no oil in the IC pipes but was in the inlet and the inlet for the turbo.

i have a vid i'll upload when its done.

there is a bit of play in the shaft but its not major

smoke under load is not good, its unlikely to be the valve stem seals as vacuum is at a minimum, under load a smokey turbo usually clears a little,
im going to say it could be pistons, or head gasket have you done a compression test?

looking at that video you have bent compressor blades and a very dirty compressor (oil? ) the turbo looks fooked!!

still not ruling out the pistons or head gasket, a smokey turbo wont stop it revving

when it ticks over there is a bit of smoke but if you rev it then it comes out alot more.

Oil going into the bores would though?

Tbh I didn't really put my foot down as I didn't want damage anything.

What would you say the next step I should take?

compression test, better still a leak down test

not really, alot of oil would cause det, and could wipe out gaskets and pistons in seconds, been there done it

That kit is for the carbon "dry" compressor seal variant...
Are you sure yours is that type ???
(I would think unlikely)

For the circlips that hold the bearing bushes in, SMALL circlip pliers.

(the GT series bearing assembly is so much easier than the T series)

From the play shown in your video, it may be more than just the bearings - the shaft may be badly worn or the bearings may have spun in the centre housing meaning std/std bearings are no good. I would pull it apart first before buying a rebuild kit.

Just my opinion though.

Take it apart - which you really need to do anyway to see if a service/rebuild kit will be OK - the dry seal is a carbon ring, the usual compressor seal is a small piston ring very similar to the turbine end.

The compressor backplate is also different between the two seals (hence why you can't interchange seals without changing the backplate).

Really need to see it apart if you think you have the carbon seal.

You won't know until you take the existing broken one apart.

I thought I said that earlier......
