gas in oil
Hello
I was just reading about someone who was having similar problems as mine. I did the cam about 500 km ago and ever since have had problems. I'm farely new to doing this sort of work, so I'm learning as I go. My main problem was low oil pressure. When the engine is cold, I have great oil pressure, but as it warms up it slowly drops off to around 5-10 psi.
I have found that there is gas in my oil and am going to replace my fuel pump. My question is should I think about doing the bearing in the bottom end? The engine only has about 10,000 km on it since rebuild.

The oil pressure sensor is at the rear of the motor in a 335 series motor, and the oil pump is at the front of the motor. All the main bearings get oil before the gauge. 5 to 10 lbs oil pressure, when warm is not unusual in these motors.
Replace the fuel pump and change your oil, with a good quality oil of sufficient viscosity not to thin out too much at warm temperature. 15-40 or 20-50 oil should improve the pressure at the gauge. When cooler weather comes again, switch to 10-30 oil.
