Through reading previous posts on this Forum I thought the heater vavle was called the monovalve and that there was a repair kit available. (from FastLane) I paid $600 for this vehicle to use as a beater (albeit a very nice one), will not buy any $400 parts. Maybe we are talking about a different part, my brother forsees no difficulty in bypassing this firewall-mounted, solenoid-controlled valve mechanism using a longer, contorted piece of hose to go from the engine to whatever heater core inlet it must reach. Other forum posts mentioned the possibility that disconnecting the A?C compressor switch might allow the valve to operate. We're trying that, I don't need A/C, drive the Porsche in summer.
Why would disconnecting the A/C allow the heater valve to work? Is it a climate-control computer or relay issue?

On the injection, the seepage apparently comes from the area where the injector enters an insert in the head. This steel insert has slots which apparently use a spanner to tighten into the head. I am having my brother look again at the area to provide a more detailed description.

I plan to attempt the motor mount replacement myself when I get the car back to Detroit. Is there a mount replacement procedure somewhere in this forum?

Yours has been my only reply thus far. When that happens on the Porsche discussion list, it's because the newbie question has already been answered a million times and the answer is in the archve or FAQs. Is there such an area in this forum I should be accessing for this info?

Thanks so much for your reply, I really appreciate all the help I can get and look forward to providing the Forum with insight from my own er, "unique" perspective. Dave Larson
