Does this look like the gasket or the weep holes on the pump? Anybody else have this?

The picture isn't of the oil pump, its inside the pan, what you see is the aux shaft that drives it. There is a gasket behind the alum seal cover. It could be the gasket or the seal. Clean the mess up first, maybe you can then see more.

Ford changed the lima block in 1995 and put the pump in the auxiliary shaft hole.

This is what the late model lima engines had:

It looks to me like the seal is leaking. Either way it's a good time to replace the pump.

You thinking shaft seal?

Dang these pumps are expensive. Like 200+.

Well amazon has the sealed power/melting for 128 so that's not too terrible.

It does look like the shaft seal is leaking to me. They are pretty expensive.

Well I got her cleaned up by soaking it with SuperClean and using some brake cleaner for smaller hard to reach areas. Ran the pump with a drill and saw fluid pumping from between the "plates" in the casing. Bad Pump



I about had a heart attack when I saw the big chunk "gone" in the block hole. Turns out this is just the way it is casted as another user on the rangerstation had pics of his and it was identical.



Looks like the pump may have been on borrowed time since the middle section looked burnt (or could just be oil staining it, but it is pretty dark).





The good thing about this ordeal is that the cam gear was off a tooth. I kept wondering why my gas millage was always around 20. Idled a little rough too. Must have screwed that one up when I replaced the belt a little over a year ago.

How many miles are on your truck? This got me thinking about changing my pump the next time I do the timing belt.

Default Re: Oil Pump Oil leak

Since I got a new pump I figured why not tear down the old one that is "not serviceable" according to Ford. Well turns out it is. There is only about 5 "hard" parts to this pump (by hard I mean metal). Front assembly (part you see on the outside of the block), rear assembly (cylinder part that goes into the block), shaft, 2 pump gears (one external teeth one internal).

As far as seals go:

Pump to Block Gasket: F57Z-6659-A (according to another ranger owner), my Melling has a F57E-6659-B6C but I can't find that on google.

Outer o-ring:87072-s100

Inner o-ring:87071-s100

Front Shaft Seal (Ford doesn't say this is replaceable but it is): E6ZE-6700-A2A (same as the camshaft seal), this part is also made by National, Timken, Gates, etc. so don't have to buy from Ford.

Inner "O-ring": Don't know part number but if you don't feel like dropping alot of money on a new pump you can probably RTV one. See this seal below. BTW this was the one that cause my leak.

Down to the teardown:

First to go was the shaft seal. Remove this just like pinion seal on your rear end. Hammer a screwdriver on the side and twist and work your away around. Then just hammer the new one in. Easy.







Then on to splitting the assembly. There are two pressed in "dowel" pins that need to be knocked out from the front. After these two are out the two parts should split easy. BTW THE HOLES ON THE SIDE ARE NOT WEEP HOLES AS OTHERS HAVE SUGGESTED. They are there for prying. You will see what I mean from the pics.









Now that its apart you can see the inner o-ring I was talking about. I'm seeing if Melling will get me a part number, doubt they will. Again I'm sure you can RTV it up if money is an issue. This seal is the whole reason for my leak.





Here you can see the area that was leaking and the area where the o-ring lost touch with the housing to let the oil out.





The only seal that appeared to be leaking was the internal one. So yeah I paid $125 bucks for a new one just for a seal. BTW Melling makes the Sealed Power one I bought. All the seals that are on the new pump are Ford part numbers, the rear assembly is a reman-ed Ford assembly but the front looks like a re-cast with a Melling "M212" stamp on it.

Save your money and by the Sealed Power one from Amazon for $125
