Rear main used to leak but its been replaced. Never leaked enough to drip on the ground or show on the dipstick but the bottom of the tranny was wet where it met the engine.
Nothing but Mobil 1 in the engine since I got it with 59K.
None, now that the oil plug has been replaced and you can actually tighten it.
There is some seepage of oil coming out of somewhere, it isn't enough to tell and doesn't drip on the ground, but it does get all over everything under the engine.
I've had three Explorers and none of them have leaked a single drop. The first two, a 4.0ohv and a 5.0, had 150k+ miles and the current one, another 5.0, just rolled over to 89k yesterday.
Mike, you need to tighten those valve cover bolts. Those gaskets are not gaskets, there is a leak proof rubber/steel seal under the SOHC valve covers. Unless the bolts are loose, they should never leak. Find an 8mm socket and with an extension snug those all up. I hate to think about the mess left from leaks, I have fixed and cleaned up many leaks before. You just have to get to it and clean and tighten. Old gaskets leak, the new rubber and steel used these days can last forever.
