Subject: Re: wastegate on an 84 900 Turbo


Jason, The wastegate is not a separate part - it's integrated into the turbocharger. The wastegate *actuator* is separate, but I doubt that's your problem - never heard of one failing. When mechanics say "the wastegate is cracked", what they really mean is that there's internal cracking in the turbine housing of the turbo - the snail-shaped cast-iron part of the turbocharger. You'll very rarely find cracks on the outside of the housing, but internal cracks are very very common. The cracks enable exhaust to bypass the turbo, increasing the turbo lag a bit. If your symptoms are any worse than a slightly increased delay in turbo action, the problem may lie elsewhere. The solution to the problem is to replace the housing with a new one, since finding a used one without cracks is almost impossible. New ones can run a couple of hundred dollars, and most people find that it's not worth it for the amount of difference it makes. Just my 2 cents!
