There was an oil leak the other day, but today nothing. The truck had been parked for months without starting then suddenly a couple days ago I started it and ran it around town and decided to look under the truck. Oil leak dripping from around the oil filter and around the flywheel housing. I have read about someone talking about the valley....but couldn't understand what was meant by: "the valley"????

Should I take apart the flywheel cover and see if the oil is coming from there???

Sucks because today it didn't even leak.......I left it on and couldn't see it leaking from anywhere. I literally went under and used a flashlight, but nothing........help!!!

Turbo plate O rings???

Fittings???

I just want to know your guys' professional opinions/thoughts incase it gets worst

BTW guys I'm new here and new at Turbo Diesels.....
GAS Turbo<----no problem...

 

The valley is the area on top of the engine, underneath all the other stuff that keeps you from seeing it. A common place for oil leaks, too. There are a number of fittings and lines that run through the valley that carry engine oil, and any leak there will likely show itself as oil dripping down the back of the block. I'd check there first.
