Update

By BobSprowl - 09/30/2002 8:24:10 AM; IP 152.1.160.205

Pulled the intake and everything was fine. Used the drill and could hear oil gurgling out near the front of the engine some of the time. Pressure varied from 0 to 38 pounds with a low of 8 pounds common and an average of about 28 pounds, but again sometimes there was no pressure at all. (Noted I blocked the holes to the rocker arms shafts.)

Pulled the timing chain cover and everything was correct there also. Ran the pressure check and no sign of a leak and again the oil pressure varied widely.

I had another 390 engine on an engine stand that has been recently rebuilt so I pulled the distributor installed the gauge and used the drill to find out what the pressure should be if
everything was OK. Got 68 pounds in just a second or two compared to the 20 seconds it took to get 18 pounds on the problem one. It took about a minute to get oil to come out around the rocker arms and the pressure was very steady.

Went back to the problem engine and it took about a minute before the gauge moved.

I'll pull the engine out next weekend I guess.

This thread, so far...
