Oil Leak @ Bellhousing? Here's Why....

This is an often overlooked source of engine oil leaks that everyone assumes is coming from the oil pan or rear main seal. Most of the time it is from split CAC tube hoses that only appear to have oil moisture to them upon further inspections. Take a look I show you what to look for how it pools up and where it all comes from and how to change them out properly so the angles are correct and there is no blow offs.

Mines had a slight bed plate seal leak since new, but has never gotten any worse, just a slight oil drip gathers on the lower bell housing. I never had it fixed even when under warranty due to my reasoning that it was not worth me having to chance my luck of possibly having some dealer hack tear my motor out and apart for a dribble..the talent can vary dramatically in a dealerships technician pool. Don't get me wrong, as I'm not in any way implying you, I would be more than happy to have someone like you work on my truck if it were a warranty situation or not.

Thanks for all the great videos and tips! Keep'em coming!

Mine has always had an oil leak. I have had the turbo replaced, bed plate o-ring has been replaced, and all boots replaced. I am going to look at what was shown in the video and see if my boot is leaking. I do not have any oil residue on the top of the boot, so I do not think that is what is leaking. But one day I might find it.

Upon tear down of my engine I finally found my small oil leak. It was the dipstick oil tube o-ring was missing.
