Dominik,
Another excellent thought...but nope, not the filter.
OK, last clue. All three guages and senders, (mechanical and electrical) were working properly. We DID in fact have
oil pressure at all times. It was the third guage that finally solved the problem.
The question reviewed: Why did two guages show 75/80 lbs of
oil pressure at start up, then drop to +/- 10 lbs, while the 3rd guage showed full pressure immediately and through out the engine break in?
For what it's worth: The motor was rebuilt using all new parts including a very special crank. (More on that later and WILL come into play with the
oil pressure issue)
The incredible story behind the rebuild: See above posts. Totally assembeled, including plugs, minus the transmission, it takes less than 40 ft. lbs. of torque to turn the motor over by hand! Is the motor built tremendously "loose?" Not on your life. Unbelievable, very, very close tolerances.
DV -- 300 Cobras is NOT enough!
