You got that CC off yet

So after Blyton the car seemed to be tapping quite a bit, as if the oil was too thin after getting it really hot. It was on 5w30. The grade varies for these engines depending on climates, age, mileage, the usual. Many people run 5w40 or 10w40 all year round. After some reading, and literally every post suggesting different things, I decided to go with crude like 15w40 - more so because Whiteley has a supply of it!
I wanted to be able to see what pressure/temperatures the oil was getting to on track because of this too, well worth knowing, especially on the higher milage engines. Made a purchase:
Brilliant bit of kit, with their software it gives programmable temperature ranges, pressure display and warnings. I wanted it all on one gauge and this is the one that stood out in quality.
Next was to decide how I was going to go about fitting the two senders to the engine. The M52 has an Oil Pressure Sensor on the back of the oil filter housing, which is M12x1.5. It also has a Vanos feed line, which is M14x1.5 on a banjo bolt. I considered running the temperature sender in the sump plug, but didn't want to be f*cking round with wires every time I wanted to change the oil.
I decided to run the temperature sender from the original M12x1.5 Oil Pressure Switch location, with it always having a good flow of oil past it at full pressure. I got an M12x1.5 > 1/8 NPT fitting and put that in.
The only other location to use for the gauge pressure sender was the Vanos line port - so I went about making my own Vanos oil line to replace the BMW one. I didn't want to mount the pressure sender directly off the engine due to vibration etc, so the pressure sender needed to be on a remote line too.
Purchased some AN fittings, stainless braided Teflon hose, and some adaptors.
What I ended up using was: M14x1.5 > -AN4 ----> -AN4 Take Off Adaptor (1/8 NPT) ----> -AN4 120Degree Fitting ----> Stainless Hose ----> -AN4 M14 Banjo
Original Pressure Sensor/Vanos Feed
M14x1.5 > -AN4 Adaptor
M12x1.5 > 1/8 NPT Adaptor for Temperature Sender
AN4 Line Assembled
Fitted with new crush washers on the banjo..
Mounted the pressure sender at the back of the engine bay on an unused bracket..
Ran the wires through the grommet that the alarm wiring uses, plenty of room there. Up the back of the dash to the gauge and wired it up. I have a 52mm gauge pod cut up and mounted in the middle of the clocks. Replaced the filter and filled it up with the 15w40. Ran it for a couple of minutes to check for leaks, and had none, all good!
Thankfully the engine is healthy, returning 60psi cold idle. Ran it up to operating temperature and it got 20-23psi warm idle. It makes full pressure (60psi) by 3,000rpm, which is great. Good enough for me!
I will upload some pictures of the gauge in the daylight at some point, along with a couple of other things that have been done. More soon
