5.9 cummins oil leak under injector pump

[jason5070]

I have a Dodge 2500 with a 5.9 cummins and I can't seem to pinpoint an oil leak that seems to be comming from behind the ps pump or injector pump is there something that commonly leaks oil near there. Its hard to clean to inspect in that area. Thanks

Jason, most likely is leaking between the vaccum pump and p/s pump. There is a seal in the vac pump that the p/s pump shaft turns in. That seal will drip engine oil where the two pumps meet. It can be fixed without buying a new vac pump, but the tech needs to know where to get the parts and how to get the seals out and back in, it's tricky.;)

thank you I'll check it out I can probably change the vac pump myself I used to work for dodge but the only time I had to work on a cummins was to change the ps pump nothing else broke.
