I've got a oil leak that I can't put the kabash on. It's driven me nuts man and I need your help!! :scratch:
So, it isn't a typical drip leak. Though I do have one of those from a leaky rear main seal. It only seems to happen while driving more than town errands and coats the undercarriage of my truck from under the front main seal all the way back to the t-case, especially around the oil filter side, the starter side isn't too bad though. At idle I see nothing spraying or dripping, yet after a drive down the highway and back its all over the place. I detailed the engine bay in the fall for winter driving and degreased everything so it was pretty tidy and clean outside of the grime I didn't brush out.
Looking for stains and wetness, it's below the head gaskets. (though I have a light seep from one head's valve cover) Checked oil filter and it's fine. I have a oil filter cooler and the sandwich adapter was a little loose but snugging it down did nothing. I recently discovered that and after a 4 hour drive the leak wasn't noticeably better.
The leak really should be a spray of some sort because the area covered and the volume is not especially high, but is enough to make a mess and drip from the oil pan area, the tranny drain plug area and the oil filter, once it sits after a drive. It reminds me of the leak from the manual tranny when the shifter plugs leak, sloppy.
Can't think of anything else thats pertinent. What are some causes for a leak of this nature?
I'm missing something obvious, like looking for the peanut butter jar on the shelf right in front of my face!!!
