FIgured it and did I ever screw up!

By BobSprowl - 10/07/2002 9:13:07 PM; IP 152.14.61.169

First I isolated it by adding 5 more quarts of oil and finding that the problem went away as the oil pressure immediately went to 65 pounds. And the gurgling noise went away.

So it had to be a leak in the pickup tube which was now submerged comlpetely in oil.

Got the new Melling pump and pickup off and found that I had installed the pickup tube gasket incorrectly. Damn. And took a real close look at the first pump and saw that it had the gasket installed incorrectly also. Now the second one was installed upside down in the truck so I can understand how that happened, but the first one was done on an engine stand and there isn't any excuse - I screwed that up.

Anyway here the things I learned.

1. If you hear the oil gurgling you have an air leak on the intake side of the pump.

2. A new pump and bearings should give you 60 pounds or so.

3. Adding an extra quart should not be a problem on the standard oil pan and with the factory CJ Windage Tray the oil still was well below where the tray would be.

This thread, so far...
