Coyote oil leak?? Greasy spot on timing cover.

The other day I was checking my oil level which I usually do once every two weeks. I noticed a wet greasy looking spot on top of the ac compressor on the passenger side of the block, as well as a greasy spot on the timing cover. This is really annoying to me, because one of the reasons I sold my 94 was because it leaked oil from every sealing surface, and I needed a reliable DD. I don't know where to begin with finding the leak, and or repairing it. It's a early build 5.0 may I mind you.

Dang! Have you noticed anything on the on the ground? Have you, or someone else recently changed the oil?

No it's not that severe of a leak. And I changed the oil about 3,500 miles ago. I only use mobile 1 synthetic, and the motorcraft filter.

What I was thinking was that maybe when you changed it, you got some oil on the timing cover, it can take it a while to show up, but as the engine gets dirty, it can create a grease spot.

Now if it's gotten worse, or larger than it may be something to look into. I'd watch it over the next week and see if it gets worse.

I think it's fine, but that's just my opinion. Let's see what some others have to say.

I don't think I spilled oil down there. Maybe the past owner did. I think I'll degreese it and see If it showes up again

Yes do that and if it reappears then it's time to diagnose. The easiest and simplest thing first.

Use the Mobil One High Milage Full Synthetic it will work on expanding the seals which may work for your case.

I do remember hearing that Mobil 1 is the worst for leaks. No idea why - but you might try RP or Amsoil instead. The high mileage idea sounds good.

Ahaaa. I think I may have found the problem! I had a warm day here yesterday and my AC didn't work. I hooked my AC gauges up and what do you know. It has more than enough Freon charge. So I check the fan clutch fuse. BAM! It's blown. That fuse also shares the high rpm pcv valve and the radiator cooling fan which both kicked on when I replaced the 5amp fuse. 5 amp seems a little small to run all those things. But hey, I think it may have fixed all my issues, knock on wood.
