So, they car has VERY few miles on it, under 5.

At starting on idle, pressure goes up to ~40.

Start driving, its fine for the fist little bit, then the pressure goes to 0 and the light comes on. If I rev with no load (out of gear, stopped), pressure comes back up.

As soon as the engine gets under load, pressure seems to take a dive.

I am not leaving any oil slicks, and there is oil in the engine (checked many many times.)

Oil smells a bit gassy, but thats probably due to the rings not being seated, as I have not been able to drive the car to seat them, and my carbs are still a little rich.

I am using the VDO dual sender on a steel flex hose to the oil pressure sender outlet.

I took the sender off and cranked the motor (no ignition) and got oil coming out of the hose. Not shooting out of the hose, but oil was moving through it.

I had put teflon tape on the end to prevent leaks, but that has been removed.

Oil pump is supposed to be a high volume pump.


Mike thinks it may just be low oil in the engine, and the dipstick is not original. We need the measurements of a stock /4 dipstick.

Mike is sooooo damn cool and I wish I was more like him. I have such a man crush (IMG:style_emoticons/default/wub.gif)
