Oil or diesel in raw water exhaust

[FBNOODLEMAN]

I removed the oil drain plug at the bottom of the pan, and had a machinest drill and tap a fitting in the drain plug..with a 2' piece of oil rated hose and a cap to close.  Now, when I want to change the oil, I attach a hose to the cap fitting and pump away all the old oil from the bottom of the sump. Works great, the only problem is getting the drain plug off. I made a special wrench to do the job. Enjoy jim, on Toothpick, Pearson PH36
