Subject: Re: Turbo going out?

Had a similar problem on an 83 900T and it turned out that the head had developed spiderweb cracks that opened up under pressure. After the head was off you could really see them. Mechanic told me he first thought it was gasket blow-by but couldn't find any evidence of that - just lucky his boss remembered this rare ailment. He said it was caused either from too much boost or from metal fatigue (the car was 10yrs old then and the boost was on the higher end, so probably both).
