I have a 1995 f250 with the 7.3l in it. I just had the motor pulled out and put a new oil pan and pick up tube on and went through it. we sealed the pan good with the recommended caulk/sealer. I got it running on wensday and it ran great and wasnt leaking anything at all. Later tht night i put power steering fluid in it do to there being none. I started and drove it again thursday and it started leaking oil heavily out by the back of the pan, and only leaked when it was running, is there anything for the power steering back there or is it possible for it to be sprayed back there? I really dont wanna have to pull the pan off again, any ideas

 

I would check the pan bolts to make sure they are all tight, cause my dad's 97 was leaking and all it was, was loose bolts

 

I did check the bolts, they were all tight and it still leaked, is there anyway to patch it without dropping the pan again? If i put enough sealer on it for temporary would it work?

 

well the only sealant I can think of would be the right stuff but that would require for you to pull the pan and get a new gasket and all that work and you already know it's not an easy task to do that with the 3/4 ton trucks

 

Make sure it is not coming from the valley and down the back of the engine.

 

when i installed my chip and started puttin more fuel to the beast, i replaced my fuel filter, it was leaking and looked like it was coming from my trans, but it was just fuel cuz the filter wasnt tight enough, i'd check your power steering, starting from the reservoir and going back to see if that could possibly have a leak.

 

go start the truck and get a flashlight and look in the valley for oil seeping from anywere.

 

I bet its the rear main seal,its the only problem I ever had with my 7.3. If you pull the motor on a 7.3 new seals front and rear mains are a must.

 

I would deffinetly check valley for signs of oil, in my history of tinkerin on the 7.3 di 9 out of 10 times oil leaks originate from the valley. Be it from turbo pedastal, ebpv seal, hpop, or hp oil lines.

 

you cant put any sort of silicone in there for no. it will not stick to oil. do it the right way and pull the engine and reseal it. if that is where it's leaking...
