Hi guys my 2001 996 Turbo is in the garage for service and we have found a leak on one of the Turbo bodies.
Lots of labour involved to replace the turbo body/shell .
Car is fine when warm but blows a bit when cold.
All Turbo/exhaust bolts have been replaced.

Never heard of this. Has anybody had this issue?

Thanks

I have replaced my turbos as an upgrade and they are not that difficult to swap.
Are you mechanically incliined/DIY kind of owner?

bigdave

Hi, no i'm not mechanically useful...

Just wondering if anybody else has had this issue, just a shame as Turbo working ok, and not the usual "maintenance replacement" part.

Looking for advice on replacing Turbo or just do the body where the leak is.

Mechanic says it cannot be welded to repair.

whats your budget? It is not ridiculously expensive to replace the turbos (relatively speaking). You could get two new ones and sell the other old one.

Why not buy a used set off of someone. I frequently see sets of K16's selling for $500-1000.

where is it leaking? take a pic and highlight the area if needed

For a turbo to leak it is likely not the cartridge but a seal on either side of the turbine shaft (leaking into housings) or a fitting feeding/draining oil.

That is a dramatic amount of metal to 'rust' through and considering its constantly getting an oil flow nearby rusting through just seems unlikely.

I'll take a look on Monday. Take some photos.

Might be cheaper to have the turbo refurbished.

Thanks

are we talking an exhaust leak or oil leak?

bigdave

Yes exhaust leak not oil!

993GT

ok on same page lol...is the leak at the exhaust manifold or the connection to the catalyst/muffler assembly? or is it on the turbine housing itself/backing plate/centre section connection?

Cars that are driven all year where road salts are used can have turbocharger issues.

The failure is bearing housing rot at the turbine housing flange. The cast iron just erodes away.

My recommendation is to purchase a set of cores from Rennlisters or Ebay. Lower mileage cores will demand more monies.

If you want to upgrade to x50 k24's and Intercoolers, PM me.

bigdave

Mechanic sent me these pics.
Will go and have a look myself Monday.

Car has been my daily driver for past 5 years.

Probably remove the turbo and get it refurbished but no rush.

Sounds just like the explanation a couple of posts back which makes me feel better. Every other repair I've had to do on the car over 5 years you can find a thread about it. First time I've heard of this!

bigdave

Oh thanks for the offer but car is completely standard apart from sat nav and plan to keep it that way as I'm a sad git!
