My 82 300SD (Garret turbo) suddenly lost turbo boost last weekend. The banjo fitting id not plugged and the circuit to the ALDA is not leaking. Measuring the manifold pressure, I get almost no boost until 3-4,000 rpm and then I get about 6 psi max. I don't see any obvious leaks in the intake or exhaust and I can hear the turbo turning.
Any guesses on probable cause? I'm wondering if the waste gate is somehow suck open. I have noticed jerky boost at high power settings (boost cuts in and out near max power) in the past so I'm wondering if the waste gate may be sticking. And If it is a sticky waste gate ... what's the cure? Thanks Scott Ritchey Kittrell NC 1982 300SD 220K 1979 300TD 350K = -------------- next part -------------- A non-text attachment was scrubbed...
