M20B25/325i No Start with Oil Pressure Sensor Disconnected?

Ladies and Gents,



I've tried the search but no luck.



I've seen the odd post on other sites suggesting a 325i/M20B25 will not start if the oil pressure sensor wire (not the oil level sender wire) is disconnected.



This doesn't make sense to me. It seems to me like the switch would illuminate the dash panel bulb by closing the circuit to engine block ground in a low-pressure condition; thus open circuit would be the normal adequate-pressure condition, and a disconnected wire would read just like the adequate-pressure condition.



I'm hoping someone could confirm the motor would start with the lead disconnected. The reason I ask:



I am finishing an M20B25 motor swap. The sucker just won't start. I replaced the stock oil pressure sensor with a VDO combination pressure guage sensor and idiot light, and it's inconvenient to go back to stock at this point. I wired the idiot light terminal of the VDO pressure sensor to the stock wire.

Parts list needed for BHG on 1997 750 il V12 please.

Recently I purchased a 1997 750 il V12 ,194k miles, white ext, beige int.... I knew it had some issues but wasn't sure what... I had the vehicle towed to my mech (specializes in European cars) and he is going to pressure test the motor today but just by looking in the oil fill area everything is coffee colored.... the dip stick wasn't when I looked... he said the head gasket is blown and that it would cost more to rebuild the motor than replace it with a used motor... but ive started looking at parts and that doesn't seem to be the case...



I saw a partial parts list in another thread but I would really like to have a complete list of parts needed for this job. if you have part No. that's cool but not needed at this time... I really like this car and would love to see it on the road again especially since so many of them out there seem to be dying off faster and faster... im mechanically inclined so if the price is too outrageous from my mechanic I might take it on myself and have a nice little winter project in my garage....



Any and all help is greatly appreciated!









thanks.. PEACE...

E38 High Performance Build

My dilemma started when I wanted to install a M5 4.9L Motor in a 2000 E38 740I Sport, everybody said no it can not be done, yet it will fit in a 95 740I? Strange, I believe it’s a clearance problem with the air filter housing configuration, not certain since I decided to research racing 4.4 L motors and I found it to be actually better, now you can build an extreme killer motor strictly suggested for track use only due to the unreliability issues, obviously it needs constant attention and who needs that as a daily headache. But the same builder also can build a toned down version, naturally aspirated and horse power that will smoke any M5 including the 10 cylinder model. As a driver I prefer and the wide body of a E38 to a E39, almost the same length but the wider stance for me allows better handling and doesn’t have the tendency as the E39 back ass trying to over take your front. This occurs while diving into a hard turn a bit faster using power to push you through, almost like a Porsche 911. Anyways my first performance build on a E38 has been enlightening and surprisingly as to the availability of various performance parts. I love the car and excited to see the finished car. The motors I’ve seen a majority of owners do is supercharging a relatively stock motor which severs to increase horse power but honestly really lacks the performance I prefer while flying on the autobahn in Germany.

Though I am committed in the engine build and like to provide the stats including the cost to build it, I was wondering if anyone has configured a M5 v8 into a E38 ever, also if anyone knows exactly why a M5 4.9 will not fit a 2000 E38, oh one more question has anyone done a performance build on the V12 motor, that was my first taste of the E38 having had a 2000 750IL, which other then being just to long to really drive hard on windy roads, the 12 performed so wonderfully and so smooth.

Buddy picked up an '84 733i with a manual..

So.. How rare are manual transmission E23's in the US?



Better pics will come later, but my work partner picked up this clean 733i. Great price too. Gonna go through it tomorrow, looking forward to it as this looks pretty cool.. it's got clean black paint and a pearl beige interior in very good shape. Also, very nice modular 16's that just need a little polishing.
