........there are two connections on the intake, i understand that the front one is for the fuel pressure regulator and the other goes to the hose coming from the valve cover breather hose. Does this one tee from the valve cover hose?

thanks,
rommel

Nice job on the mileage. How long have you owned it? Original top / bottom end / tranny? Anything? Gives us hope.

Best of Luck,

in almost 10 years of dealing with these cars i've not seen anything there, it must be for a euro car, i seal it with a blob of rtv or jb-weld would be better just give whatever you use time to cure before you run the car or it'll get sucked in

the original snapped off due to britalty... bought a new valve and used the old rubber bung. if you don't it'll suck air in and lean the mix badly. Perhaps it is a good spot to take off vacuum for a vacuum gauge if you get one (perhaps BMW use it on one car with this valve that employs vacuum powered accessories, but I don't know of any.... who knows...) :) GP

All is still original, been using 15w50 mobile one since we aquired her at 30k. I have given her to my brother who just graduated from University of MD. We replaced the head gasket cause of a mild coolant leak on the exhaust side and cant figure out what plugged into this.

This comes in handy when vacuum testing, or running a squirt Seafoam or TB cleaner down the intake.

The valve (I'm sure you know) is the non-return valve for the brake booster. When I replaced mine, I asked a parts specialist at a BMW shop about that little port. He said it was some kind of test port for your vacuum system. There is another part (I can't find the number) that is a plug for this port. The guy told me to just plug it with some kind of sealant.

on an m20 of mine it has that same connection coming off the hose from the brake booster and it is connected via a hose to a plug on the fire wall which in turn routes it to the temperature sensor over the drivers feet - the idea is is sucks air past the sensor giving an acurate reading of temperature
