Oil leak problem
PLEASE I NEED HELP ASAP, AS I NEED MY TRUCK FOR WORK AND I JUST GOT HIT BY HURRICANE BERYL, SO I GOTTA GET BACK TO WORK!***
So I have an oil leak, and it doesn't leak till truck warms up then it leaks like a s.o.b. AFTER DEIVEING 30-45 MINS it leaks about 5-10 quarts but I can find it. I've read about the hpop hoses, seals, o-rings etc. I have it taken apart as far as the fuel bowl removed and the alternator removed(alternator so I could see better) and 1 hose off the hpop (front hose off hpop, and there is NO o-rings in sight) . But it looks like the leak is coming from behind the alternator. But I can't tell...... IDK what to do..... Can anyone PLEASE HELP . it's my work truck and personal truck..... I'm tight financially but I'm good at working on cars/trucks and I have most sockets and wrenches..... (Btw the hpop was replaced by a shop about 9 months ago, for $2000+) ( The truck was given to me by my uncle and he was the one that paid that money😱
I'm stuck.....🤬.....

For four decades I was owner/operator of an auto repair shop and I found a brand of auto parts that I grew to trust because of the quality of the parts that they supplied. If you're tight on money, you can get a Mahle brand oil cooler gasket kit for your oil cooler and do the repair. I just purchased this for my truck and I'm about to dive into it in a couple of weeks. At the time of this posting the kit is $25.00 and change. Don't be afraid of Mahle, I used to prefer them and one or two others over the rest and never had a failure that wasn't improper installation or something like that.

Reply to my oil leak
So I removed the bowl and alternator like I said and so I pulled off 2 lines on the hpop and there are no o-rings but none have o-rings, so are they not needed?? And yes there is oil in the valley but it looks like the fan is blowing it back and when I do start the truck I don't see ANYTHING ON THE TOP END. OT JUST LEAKS AND IT LOOKS LIKE ITS COMING FROM BEHIND THE ALTERNATOR. (Sorry FOR caps). I'll put some pictures now.. I'm off of work, luckily my boss/uncle picked me up today but I'm off and I'm trying to work on the truck now. How hard is it to replace the oil cooler gasket that y'all are saying it is.???

The oil cooler is that big pipe shaped object that is bolted up to the engine block below the driver's side cylinder head. The rear housing, IIRC is also the oil filter flange assembly. It's bolted up to the block at both ends, and again, it's underneath the left exhaust manifold and shaped like a 2" diameter pipe in the middle.

That leak looks topside to me now that you’ve shared the photos. I’d be surprised if it were the oil cooler.
I would guess the HPOP line as you’ve been considering. A very small hole will create a lot of oil due to the high pressures it runs at. I had one break in the line itself after doing some work and moving them around.
I don’t remember the exact configuration but there are orings for those fittings. They may be inside the female end or back under your rubber. Seems like there were 2 per fitting. I highly doubt missing orings is your problem because that would have leaked immediately.
edit: I had to go look it up. The orings are inside the female fitting. https://cdn.shopify.com/s/files/1/07...f?v=1688160322
As others have mentioned, I would clean it up and then search for the leak. A leak that big should show itself once the surrounding area is free of oil.

Oil leak ???
****PLEASE I NEED HELP AND ANY ADVICE**
That's just it tho I have tried to look and the only spot I see a leak is after it runs for a out 5-10 mins I see it dripping underneath coming from what looks like the alternator area. The valleys fill up because of the fan I THINK, cause I don't see nothing leaking from the top. I'm so baffled... I don't have the money to keep fixing what j THINK is the problem. And I don't see non o-ring spot on the connector area. It seems like only after it has warmed up and POSSIBLY created some pressure that it starts to leak.....ALSO IT LOOKS LIKE THERE MAYBE SOME FUEL IN THE OIL PAN WHEN I CHECK IT AFTER IT HAS LEAKED. ITS got the viscosity of oil fuel mix when I put it between my fingers.
