I am working on a 1985 300D (CA emissions). The turbo does not seem to work, and the car has less power than an N/A 300D. There is vacuum only at the ALDA from the boost line. Normally there is a little vacuum at idle, and more pressure as the engine speed increases. Could the waste gate valve be stuck open? Could the trap-ox be clogged? Viewing the compressor wheel with the intake tube removed, it seems like the wheel speeds up with the engine. There is no pressure on the hose going to the waste gate actuator. Anyone have any ideas what tests I can perform to locate the problem? I have a spare trap-ox turbo, but I don't want to replace it if I don't have to. Thanks in advance......Rich
