7.3 Ford - Zukman - 03 Sep 09 91 Ford 7.3 oil leak on top of engine. Valley pan filled and running down front of engine? 7.3 Ford - ChevyKev - 03 Sep 09 1 possibility - isn't there an oil breather type of tube running to the turbo? 2. The very front of the engine, kind of built into the front housing - is,'t that the high pressure oil pump? That would make the most sense to me if it is coming from the top front. 7.3 Ford - ChevyKev - 03 Sep 09 The tanish thing with the sticker is the high oil pressure pump housing, no??? Here it is cleaned up - and you can see the turbo has two openings - one to the right and one facing this picture - and there is a black circular opening to the left that a tube connects those two spots - just behind the fuel filter housing. In this shot the pliers are sitting on top of the high oil pressure pump housing and you can see lines coming off the back of it. 7.3 Ford - ChevyKev - 03 Sep 09 Aha - I was a bit wrong... The tanish thing is a high pressure fuel pump that is gear run. It has a weak and notorious seal that tends to leak. A very likely culprit. 7.3 Ford - Zukman - 03 Sep 09 Mine is a non-turbo IDI engine, I think it is coming from the gear drive for the Injector pump. 7.3 Ford - AKMark - 04 Sep 09 It's very probable that you are right in where you think it's coming from. You could get some oil dye and use a blacklight to see where it's coming from.
