Oil leak

I have a 1999 Ford Expedition that has an oil leak above the filter, is this coming from the oil pump seal?

 

Try cleaning all oil off and recheck,use a aerosal brake cleaner for it dries very quick.Possable oil sensor,seen alot of these leak.

 

I tried that and the oil is leaking from above that

 

I tried that and the oil is coming from above the sensor

 

Tell me what size your engie is please?

 

5.4 liter motor

 

5.4 liter triton v8

 

If it is the oil pump seal is it hard to replace

 

The oil filter screws to a housing that bolts to the engine block........Those gaskets leak like a pig........Some Expeditions also have a remote oil cooler and the "O" ring on the cooler goes bad as well.........The "O" ring, naturally, is not available seperately........making you buy the entire cooler. I'm told you can replace th O ring with one from a filter.........tried that twice with no luck

 

so is removal of the oil pan and timing chain cover necessary to replace it

 

Possibly, but let me check other possibilities in the morning when i get in to the shop.I have a 99 and will check for other possibilities.when you say oil pump seal are you refering to the front crank seal, if so, no not a hard repair.

 

The manual I looked at showed a picture of the oil pump housing, which the filter threads onto,is there a seal between that and the block

 

I am not sure how the Oil Pump got involved since it is mounted on the front internal, but the oil cooler removal for 4x2 is



Drain the engine cooling system.
Remove the drain plug and drain the engine oil.
Remove the oil bypass filter (6714).
Disconnect the coolant hoses from oil cooler (7A031).

Installation

For the Oil Adapter
