Developed an oil leak recently. Kinda expected some leaks since this week was the first time the truck has been highway driven for more than a mile or two at a time for about a decade; possible dried out seals/gaskets, suddenly under constant use again.
I think its either the oil pan gasket at the back or the rear main seal;
Its leaking from the seam that is the oil pan to the trans/bell housing plate, but only in the center side to side,(its clean of mud and wet with oil for about a 2" gap in the center) The rest of the pan is dry- sides, bottom and front. As is the rest of the trans. And yes it Is engine oil, Not tranny fluid.
Its running down that lower plate on the bell housing, some over, some behind that little flywheel access cover on the plate- straight down that cover and dripping to the ground.
If its the rear main seal, would it leak down inside the bell housing and run out the bottom(basically not seen till it comes out he bottom of the bell housing)?
Or come down from where the oil pan meets the tin cover on the bell housing(basically outside the bell housing like I have)?
Or could it do both/either if its the main seal?
Trying to get a feeler here for if it sounds like it is that seal, after all if I can be sure its the main seal, I won't bother doing just the pan gasket first... I'll just go after the main seal-- Its not like doing that seal is a new thing for me, done two other trucks before, although its been a while... but even so, its not something I want to do if I don't have to.
First thing tomorrow morning I'll tighten the rear pan bolts, since my Dad has had that happen before and cause a leak here; simple bolts worked loose... But until then, I figured I might as well get any thoughts y'all might have.
