[Full Leather]

Thanks for all you replies re. Turbo trouble. It looks like I've got a seized turbo which needs replacing. Does anyone know how to find out which model I have fitted? It is a Garrett and there is a small plate on the housing with CHRA44385495C 027 T? These numbers do not seem to denote the model no. The car is a 91 2.3 SE 16- Haines state it should be a T25M but how can I be sure? Presumably the model type is located elsewhere. Also prices for a recon unit seem to be around £300 is this about right? Thanks

The plate on the top of the turbo is where all the numbers are usually found. If the numbers you have quoted are the only ones there ten that should identify it to a supplier. £300 is about right unless you know any contacts in the motor trade.

The 'spooling up slowly' description does sound more like a seized (i.e. coked up) bearing than a wastegate coked up. In which case a new/recon turbo is the best option.

But if it is simply the wastegate, I had my unit disasembled by a mate who runs a local guarage and de-coked for a standard labour charge of £45. (Plus-gas didn't work in my case!) Most of the Turbo specialists would only quote for a replacement unit which was alot more bucks.

Saab Turbos run on semi synthetic or synthetic engine oil (as specified in my 1997 handbook) should never have bearing problems. It's low spec. oil which gets fried in the turbo heat which deposits carbon in the bearing channel that causes the problem.

Otherwise apart from wastegate sooting up they normally run for 200K plus easily with no problems.
