#1 V12 Oil Pressure
Posted: Sat Sep 22, 2018 9:37 pm
Hello,
Pleased to report some progress with my V12 1972 LHD import.
The body needs some work to make it sound and I will be removing the engine as a part of the process. A few months ago I was pleased with the result of my compression test so today moved on to check out the oil pressure prior to removal. I removed the dud oil sender ( not easy given its location) but then found that I did not have room to attach my mechanical oil pressure guage fittings. Replaced the old sender with a new one from SNG. I then removed the oil light switch sender and with the help of a thread block from James Listers was able to connect my oil pressure gauge.
Started the engine and ran it for a few minutes, while cold and running on choke my external gauge and the now working dash gauge both reported 75psi. The ambient temperature was circa 11 degrees. The engine sounded smooth and without any worrying noises. I shut it down after a short time as all four carbs were badly leaking petrol which was pooling on the floor. (Carb Rebuild definitely required). I had intended to allow the engine to come up to temperature to check where the oil pressure settled to when warm however given the petrol leaking everywhere I thought better of it.
With good compression and oil pressure I’m now think that the engine is serviceable and that a full rebuild is not likely required. Following removing the engine I intend to drop the sump and inspect the big end bearings as a further check.
I would be interested if based on my findings so far would you take a different course of action with the engine
Many thanks
Nick
