    This sucks Mike!

    I ran from Columbia, SC to Boiling Springs, SC with a push rod through the rocker cover towing a fiver. Not sure how much oil was pushed out of yours but these motors are pretty tough...to a point...

    i am sorry to see that Mike. i am wondering if you were not a victim of a bad fitting, but a victim of fatigue. that is more than most manufactures hang off a fitting and these engines have some serious vibration.

    edit-oops to late i see you already mentioned that

    That's a nasty pill to swallow! Hope there's no damage! Would one of those "blackstone" reports offer anything useful in determining possible damage to bearings?

    I have to agree on the fairly tough part.

    When my 88 still belonged to my oldest son, he had loaned out the truck. He got a call about a coolant leak. He went to fix it, he found the heater hose from the head, was split at the head. When he pulled the hose off, he wasn’t gentle (it was cold, and wasn’t overly happy he had to work on the truck) he broke the heater core. This was discovered almost immediately, so the truck was parked in the driveway of the person it was loaned to. Over the following weekend, I went, bypassed the heater core (just looped the hose from the head to the water pump). I fired it up, and drove it home, about 3 miles. Parked it in the driveway and left it. Several weeks went by, and during that time, I became the owner of the truck, and I decided I was going to fire it up and move it. The city had been feeling froggy about non moving vehicles, so I wanted it in a different place in the driveway. I checked the fluids before hooking up the batteries and giving it a whiff of start ya bastard.... it took 5 quarts of oil to get to the add line, and 4 gallons of coolant to top the cooling system off.... I had oil pressure, and it didn’t overheat in my short drive. I still moverit around (needs tires, beyond badly) and all is good.

    So as long as they have some oil and coolant in them, they will make it......

    So sorry to see that Mike. I had a similar issue several years ago on my F250. Had the factory and aftermarket oil pressure senders on the turbo's oil block. Didn't break, but the SOB cracked. Luckily I caught it in time. Since then, I just put a T fitting at the turbo oil block. Supply comes in one side, the other side runs to a remotely mounted oil sender on the passenger's side firewall (with a bracket).

    Wow Mike, that sure sucks! Like everyone else has said, these engines are some tough old bastards and I'm sure you'll be okay. Still sucks though, with all the work you've put into having a nice fresh set up...

    Engine seems to sound fine in your video. Oil analysis should tell you something if you can get some mileage on the next oil change before the bearings sieze, lol. I ran mine out of oil once, or almost did. Drove off without checking for leaks and oil filter was pouring oil out. No damage was done.

    I have something I need to now change on my straight six before I drive it again. There's a 6 inch 1/8 npt pipe I stuck out horizontally from the stock oil sender with a 3 way T so I could use the two open ends of the T for my mechanical gauge and still leave the factory gauge in to not have a dead gauge. Probably a lot of weight on those threads in the block.

    Hope your engine turns out to be fine, sure sounds fine to me in the video but after my turbulent start with my 6.9 I know you feel better when you know for yourself.

    Okay. Time for an update. After scratching my head about how to solve this problem. I came up with this.
    5038238F-5526-44E2-B95E-228543083B52.jpeg

    I ordered an aluminum manifold and a 24” stainless braided Teflon hose. Good to 450 F. It all came from McMaster-Carr. I bought a “one end swivel” hose. Little did I know it actually came with a stainless AN adapter. Some 1/8 plugs and a couple reducers and we are in business. I also traded the brass elbow in the engine block for a stainless version since I was ordering anyway. Here it is all installed.

    Feed line comes in the bottom. Top two holes are plugged.

    B21CA217-A3D1-4A35-98D5-54A816F86FF1.jpeg

    The good news is that I have pretty much the oil pressure I had at the first start back last year. The bad news is that I still think the sender is bad. As it started to warm up, gauge was back completely on the peg. Behaving just the way it did the other day. Ground the sender wire and the gauge pegs full. Luckily I bought a sender the other day. I’ll swap it and the factory one (it’s never worked).

    But this is progress.

    Yeah, it worked out pretty well and was a ready made solution. I would have made basically the same thing but with no shop access any more, $20 and next day delivery made the manifold a no brainer. Love McMaster Carr. They may be more dangerous than amazon.

    Elegant solution. I need to do this. Would you please provide the part numbers if you still have them? TIA...

    I’ll try to remember when I get home. Poke me if you don’t see it in the next day or so.

    Parts list:

    Stainless elbow. 2684k14

    Manifold 5975k11

    Hose 4552k121

    1/4 to 1/8 bushing. 4464k261

    1/8 plug. 4464k561

    I had 1/4 plugs of the same style. You’ll need one of those. If you can find the correct fitting to go from the -4 (I think) to 1/4 npt you can loose the bushing. I already had the turbo feed line. It was a package deal from Amazon I think.
