Another Crime Solved eh?

Indeed! hahah

Should be idling around 700-800 when nice and warm, Mine idles around 500-600 but thats coz I like the poping noise from my backbox-less exhaust haha. The oil in those parts you took off is quite normal over time, its caused by a bit of blow-by and only becomes a problem if it starts reaching the air filter and clogging it up

You can tweak your idle from the throttle body (Yes, you diagnosed where that part was correctly). Keep at it matey! You will learn ALOT from this site (Trust... Me... You will)

ok bit more to my last reply........ ICV at 90 degress this is called a L shape ICV and there is also a T shape ICV around 1988, BMW decided to change the rubber boots, so now if you go to BMW and ask for the rubber boot you'll get the rubber boot for a T shape if you need one for the L shape ICV you'll have to ask or supply them with the serial number from your old one. (found this the hard way), oh and if your intrested

Rubber boot for T shaped ICV is just under £20

Rubber boot for Lshaped ICV is just under £19

straight from BMW, bought one of mine from ebay £24 and its noway near as sturdy as the BMW ones.

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.

      105C thermostat replacement

      Not sure what engine your running but there should be a Temp sensor in the Hose from the Rad to the water pump then there should be a Temp sensor in the housing for the Thermostat Both are shown in realoem for the 3.5 V8 I thought the V8 was the only one with dual use sensor on the Thermostat housing but stand to be corrected Dave
