Many Thanks for all the feedback. It was the connector between the oil pressure sender and the wiring harness. I didn't realise that this was the failure mode of the switch. Quite a relief, this list has been most helpfull! David 87 Syncro Westy

<< now that it is finally back together I have another alarming problem. The engine started first time and ran great EXCEPT that the buzzer and oil light come on almost as soon as I get the rpms above about 2500 - there are no oil leaks. It is also very noisy but it sounds like lifters to me which would not be unexpected. Could I have ruined the engine when the seal went (it may have been a couple of minutes before I noticed it and stopped and I was driving downhill at fairly low rpm's with a cool engine) and would this be the most likely symptom. Or could I have done something wrong that would cause this. >>

1/ Make certain that the conductor is connected to the dynamic oil pressure switch (1.8 bar) at the nose of the engine.

2/ If it is connected, check the oil pressure.

3/ If the oil pressure is kosher, go to the hassle of changing out the dynamic oil pressure switch. You'll need either a skeletal deep socket or (this is probably easier) to remove the crank pulley.

4/ If the sound is like clacking from hell and not a knock, it is the lifters. Pour some Marvel Mystery Oil into the crankcase and go for a drive. The engine will start purring within ten to twenty miles.

5/ Whenever your engine puked its oil, did the oil warning light go on? The seal doesn't see engine oil pressure so as long as you caught it before the engine was bone dry you should just go to sleep and have pleasant dreams about Angelina Jolie.
