Another new 12 valve

[7.3_IDI_guy]

I bought my new 12cummins valve about 2 weeks ago and discovered I have a pretty good oil leak. Its comin from the drivers side of the block. But I can't pin point it. Where are the bad about leaking on that side of the engine?

Depending on where its at its most likely the vacuum pump needing to be resealed. Other things that can leak is the oil cooler thats on the side of the block and the oil pressure sender. Valve covers possibly as well. For me i had the vacuum pump and the oil sender leaking. Vacuum pump resealing at a shop wasnt to expensive i think it cost me $150 3 years ago and that was at a dealer.

Drivers side would either be vacuum pump or lifter gallery cover. Both are common. You can get a vacuum reseal kit from a cummins dealer for about 20 bucks. It is a little tricky to install and takes patience, but it can be done by the average joe. Lifter cover is a little more involved as it requires removal of the injector pump and other components on the side of the engine.
