Oil in turbo intake.


Recommended Posts

Hi all,

While taking my car apart to sort other issues I noticed some oil in the rubber elbow that attaches to the turbo inlet  from the air box. 

There was also a small amount oil further up past the outlet, in the short rubber hose join between the alloy pipe and the throttle body. (Where I have a dump valve installed). I notice this a few months ago. Now I’ve seen the oil in the inlet elbow I’m somewhat concerned. Should I be? The other side is dry. The car was running fine

Your oil seals are worn.  How are the general health of the turbos?  Is there more shaft play on that side than on the other?

Hi mike. 

That’s what I thought.

I couldn’t find any play in the turbo. I just tried to give the shaft a wiggle and couldn’t feel anything. 

I haven’t had a chance to give them a good inspection. They are still on the car. It has been sat for sometime. 

Is this a good excuse for an upgrade?

cheers

Could well be.  At least with 360 deg bearing and staggered gap oil seals.   Turbo Dynamics do a very thorough and reasonably priced overhaul.

I had a look at the turbo today. It has some play in the shaft. It’s not noticeably different to the other turbo. It has some marks/discolouration on one blade. I also have another complete engine on a stand. The turbos on that have the same / similar play. 

It looks like a bugger to get off. The bolts are completely corroded away. Looks like it may be easier to take off the manifold and then remove the turbo from the manifold on the bench. 

I’m  assuming that  it’s possible to remove the manifold without engine removal. 

Cheers.

Mike,

Just spoke to Turbodynamics. The guy there confirmed your thoughts. Way cheaper than I thought for the refurb and upgrade. 👍👍

He also said it would be ok to run the car. As long as it wasn’t using oil or smoking. 

But obviously would need some attention in the future.

Good stuff.  Turbo Dynamics are a great company to work with.  They really care about their work and you don't get stiffed like some of these refurbishment companies.

You will really struggle to get the exhaust manifolds off with the engine in-situ.  It's possible, but only when all of the fixings are very fresh - even then it's very tricky.

I think I’m going to leave this for now. I’ll clean it out and inspect it when the car is running again.

I have some other ideas. Bigger turbos and intercooling.

 I have another complete engine which I’ve no idea of the condition.

I’m thinking of maybe rebuilding it...............🤔
