Help! 7.3 hpop leaking

Last Friday I parked my truck at school and went to class and after my class which is an hour long. I go to my truck to go to work and find a huge puddle of oil under the truck and whole engine cover in a thin film of oil on top. So I get it towed home and started into the truck the next night. Dad and I spent an hour trying to get the truck to leak and nothing so we took it around our block roughly 4 miles. Finally I find the leak and it the line furthest to the back on the hpop and now a stream of oil is coming from it . So I took the resvior off and the fuel bowl. I change the o-rings and some other things while at it. So tonight I replaced everything and put it all together and fired the truck up ran it on high idle then reved the engine. As of now no leak so I go back around the block at first ran I easy then fast to simulate every kind of driving i do. Bring it back in the shop and same exact thing with same line it seems like I did exactly nothing. So I manage to squeeze a wrench in and take just the fitting off and my o-ring is missing like a quarter of it. Should I go to Ford and buy their o-rings which is 30 bucks for like 5 rings or is my fitting bad or has a bur on it that is cutting my ring. Any help is great I'm tired of driving the spare ranger around.

its not the o-ring, thats making it leak. You need to remove the hpop, get urself another set of orings, and LOCTITE..cant remeber exact loctite # to use, but its the sealant that makes it not leak, not the o-ring.

Went to Ford and just their kit I paid 28 bucks for 3 o-rings and some loctite. The number on the loctite is 680. May be a dumb question but what is the loctite for and how tight should the fittings be like snug or what

Yeah sad thing is I know the parts man at the dealership so I got a discount and he told me that the dealership buys them for 20 bucks. And mind you that's with taxes

Update on the situation used new o-rings and the loctite and let it sit for 24 hours and started it and ran the truck at different speeds and acceleration and she is dry of oil. The o-rings from Ford or aftermarket are a lot harder than what you can find at the hardware store. Now I know for next time that spend a little extra and don't go the cheap and assume that something may work. But thanks for the help guys I will be on here asking question about any job I do to the truck so I know what to do.

I know this thread is old but i have a question and I think I know the answer but am not for sure. After fixing the oil leak on the hpop lines I put a couple hours of drive time on the truck and checked the oil level and everything is fine. Well last night I was about a quart and half low (but still in the safe zone), also the turbo pedestal leaks I think, but its a very slow leak. So my question is in a month time my oil level dropped quicker than normal for my truck is that due to me fixing the oil lines and the system is working out air caused by fixing the leak. Thanks guys
