turbo tolerances ?

is roughly 10 thou. Is this

Still like new then the shaft runs on a bed of oil in this gap to change the bushes is not feasible as you have to split the turbine and the compressor then rebuild and balance it bearing in mind they can spin in excess of 100,000 rpm so any imbalance will show itself dramatically

Thanks for that Andy,

I can get the bearings and seals repaired by AR Turbo systems in Bradford for 125 quid, which I suppose must include rebalancing the wheels.

I have a nasty feeling the seals are goosed though because there was a small pool of oil inside the compressor body when we removed all the hoses.

The seals aren't a positive seal, they're just like a piston ring and leak a bit. Try it first and see what happens - it sounds like it could be fine.

Is that the lot on Killinghall road?

Seen it before on my old R5 gt turbo, nowt wrong with it as i had it checked by a local turbo specialists.

Hmm. Thanks for that too. The engine had 190,000 on it and the middle two pistons had failed, with scoring from bits released from the top edge of the pistons on the front walls of both pots.

My working thesis was that the engine had at some point runaway, from the oil drawn in from the bearings, but I don't know what the working tolerances are supposed to be.

I think so.

Sounds like I am worrying un-necessarily.
