Well, I got my mits on a gauge, abeit an industrial one and I have some really perculiar results. I'm trying to diagnose what is going on, so heres what I can confirm.
I've uploaded a recording of the engine running,
listen to my tappets hereWhen engine is cold, cylinder pressures are:
1. ~12 Bar
2. ~12 Bar
3. ~12 Bar
4. ~12 Bar
When the engine is hot (90 C oil temp), cylinder pressures are:
1. ~11.5 Bar
2. ~11.5 Bar
3. ~11.5 Bar
4. ~11.5 Bar
Cyl Head cold engine oil pressure 1000RPM ~4 Bar
Cyl Head hot engine oil pressyre 1000RPM ~3 Bar
If I rev over 1500RPM the gauge maxes out at over 5 Bar
When I turn the key to IGN, oil pressure light flashes
When engine is running, oil pressure light is off
If I ground the blue wire to the head oil pressure sensor, the light flashes on the dash
If I remove the wire going to the oil cooler pressure sensor, nothing happens
When the engine is running, the sensor is grounded
When the engine is running the wire going to it, is 12V
Spark plugs are black around the base and grey at the tips
Exhaust was smokey, but did not smell of burning oil, car also hadn't been run in 2 days (photo taken immediately after starting)
