Any of you guys experience leaks after putting synthetic in your high mileage engines, trans,etc?
Yes, but the leaks stopped with a switch back to conventional. In my 85 synthetic leaked out the back of the valve cover, blend oddly seemed to leak out the front, and conventional stopped it from leaking. No issues with transfer cases or transmission, but both are rebuilds within the last 30k.
