2001 excursion with V10 and 106,000 miles. Developed an oil leak after a long trip (approx 500 miles). The oil leak is not the front main seal. The leak is coming from the side of the engine block on the drivers side, towards the from of the motor. I believe there are some oil related parts in this area but I need help identifing what I should be looking for. The leak is pretty heavy when the motor is running but stops when the motor is shut off. I know this is probably not enough info but hopefully it will be a good start.
yes dito for above but also clean off the oil pressure switch and check it. it's right there and a part well known to leakage problems.
if you don't use one use a motorcraft oil filter. they are less known to cause leaking problems over some of the much cheaper branded one's . my wifes jeep will leak with anything other then a mopar filter no matter how tight we make it. same goes for my fords . oem is better all the time filter wise.
sorry guys i have a brain fart as to who makes the ford filter right now and i will admitt that brand is the only after market one that works correctly. and not leak
Happy New Years to everyone who contributes to the V10 Forum.
I always though Motorcraft oil filters. ( I like them and would use nothing else on my V10 ) were made by Wix but I found this article in Wikepedia that says they are made by Purulator.
Major brands of oil filters available in the U.S. include FRAM (a Honeywell brand), WIX (an Affinia Group brand), Purolator (a joint venture of MANN+HUMMEL and Bosch), AC Delco (a General Motors brand) and Motorcraft (a Ford Motor Company brand). Some brands, such as Ford's Motorcraft and GM's AC-Delco, are manufactured by other companies (i.e. Purolator for Motorcraft) but are generally designed and quality tested by the brand selling them. Many of the brands manufacture filters for a wide variety of makes and models of vehicles. For instance, Motorcraft sells oil filters that fit GM, Chrysler, Honda, and Toyota vehicles, in addition to Fords. The manufacturer usually provides a list of what makes and models they supply filters for.
Some have argued that there is a major difference in quality of various oil filter brands, and some studies have proven it. Generally speaking, those branded by automotive manufacturers (such as Motorcraft and AC Delco as listed above) usually meet higher standards without costing significantly more than cheaper-made (and poorer performing) brands such as FRAM or Pennzoil brand. Very expensive brands such as Amsoil, Mobil and K&N perform excellently, but cost a lot more than traditional brands.
Many major auto parts stores (such as AutoZone, which sells the Valucraft brand and NAPA, which sells NAPA Select and NAPA Gold) offer their own brands of oil filters, but these are also made by other major oil filter makers.
Perhaps the largest original design manufacturer of filters in the U.S. is Champion Laboratories, which manufactures at least some of the SuperTech, AC Delco, Valucraft, and many other filters. STP (licensed from Clorox) and Champ are their own brands. Champion was also a major supplier to Bosch USA until Bosch bought an interest in the Purolator company.

Had to go dually to get the payload of Ford F350 SRW but like the truck so far..... my ugly duckling!!!
Followup to my oil leak; the oil filter had a crack in it about an inch from the bottom. The filter was a FL-820S that was about six months old and was rusted around the crack. The truck had been running about five minutes before the oil started leaking out. The oil was Mobil 1, 10w30.
I don't get anu oil on the ground, but smell oil burning whne I stop her hard.
My bellhousing is also damp ever oil change, but I am not losing anything measurable from engine or tranny.
Change oil every 3k motorcraft 5w and mc filter, 135k change coming up soon.
I have not checked it out much, I need to get a step ladder or something, it is easier to check the underside then it is the top.
your rear main seal is leaking. i just did one on the race trailer hauler/RV with V10. it was dripping onto the y-pipe, and thats why you can smell it when you stop, its spilling out of the bell housing.
I believe the chances are greater its leaking from the valve cover gasket, than between the head and block. It might not look like its running down the head as its hotter when its running than the block is.
i hope your right. But is does not look like it. Also, the valve covers look like their design would help prevent leaks.
Again, i have yet to rebuild or tear into one, but it looks to me like the covers are flat, and would just keep oil from splashing out. Instead of actually holding oil in like th eold type velve cover did on say a 460.
hopefully monday i can get to looking closer for the leak, and update
