I have been battling the constant drip, drip, drip of the oil drain plug since I got this truck.
I bought a new drain plug and washer from Cummins, did not help.
Last night I changed the oil and added a large rubber washer and thought I had it fixed. Today when I got to work, I checked and there it is...Drip, drip, drip.....
My oil pan has that funky drain plug system that you just loosen a couple of turns and the oil drains without removing the plug.
A friend has an insert in his pan to eliminate this feature and his does not drip.
How can I resolve this. I am tired of the underside of my truck looking like a oil refinery........

 

Genos garage has a oil drain valve that you just screw in & turn a **** when you want to drain your oil....looked like a nice kit.

 

Geno's also sell a replacement HD plug. The stocker flange breaks fairly easily. SNOKING

 

My '96 was doing the same thing. Broke the flange on 2 OEM plugs trying to get it to stop. Bought a heavy duty magnetic plug and nylon washers from a guy named Pablo Madrid. That was a couple of years ago & not one drop since. PM me if you want his email. Very reasonable prices.
