I changed my engine oil last Sunday, to full synthetic (Valvoline) with a Bosch filter from local Advance Auto.

Removed old filter, opened drain plug let it all drain for probably 30 mins, then filled filter with new oil screwed it on inserted drain plug and put just over 5 qts of new oil in. All done on a flat garage floor surface.

Now i have an oil leak! So i got underneath thinking maybe filter or drain plug, nothing from either they are nice and dry, however the oil looks to be coming from the joint where the engine (right by the oil pan) meets the transmission.

I is that area a prone leak location.

Maybe it was just coincidence that the gasket between the two joints was about to go any way but wow.

Is it a big job to get that repaired?

Thanks

Sounds like your trucks rear main seal is on its way out.
Switching to Synthetic probably exposed it.
Major PITA to fix correctly.
You could try an additive to remedy the leak for now. But the seal should be replaced eventually.

 

I have heard of that on a few occasions as well. When people swicth to synthetic it finds week spots in seals and gaskets that dino oil only seeped through.

 

rear main leaks are common on bigger engines. Ive never seen one that DIDNT leak after a lot of mileage. They might not drip with oil but the leak all the same

 

So weedahoe do you think its the rear main seal? will pictures help guys?

 

So i cleaned the area down thoroughly with some decrease. I put my wrench on the 2 bolts and cranked them a little both turned about a quarter of a turn. Looked at a few additives No Leak or just a heavier weight oil?

 

Pictures always help
