In Australia, we have Isuzu Trooper powered by an Isuzu 4JX1 Turbo Diesel 3.0L engine - (kinda like half a Ford Powerstroke 7.3L). Isuzu designed the engine with 2 Oil Pickup Pipes, that goes to 2 separate Oil Filters (Z600 for Lubrication & Z79A for HEUI). At approx 120,000miles (200,000kms), either of both Pickup Pipes will experience bracket fatigue and the Pickup Pipe will fall into the Sump Pan, due to excessive vibration and lateral pendulum effects from Oil sloshing in the Sump. If it is the shorter HEUI Pickup Pipe, then it's not a terrible problem, as you can add approx 1L of Oil to overfill the Sump and operate the engine without too much trouble until it can be repaired. But if the longer Pickup Pipe falls into the Sump the Lubrication Oil pressure will drop to ZERO and not long after the Turbocharger will strip the Journal, blow the Oil Seal, and fill the exhaust with engine Oil - possibly even the engine will run-away, as the Turbo will also feed that Oil into the Intake via Intercooler. This problem was solved by adding a 2 inch (50mm) high Spring, and 50mm diameter onto the bottom of the Oil Pickup pre-filter housing, then refitting the Sump Pan. The Sump Pan and Pickup Pipes are now connected via Springs, which transmit vibration to the Pan, resist lateral pendulum forces, and push up to hold them in place so they can never fall out again, and also helps reduce wear on the Pickup Pipes Seals. As forest gump would say - one less thing to worry about.... Begs the question - "Why don't all manufacturers put a Spring on the bottom of their Pickup Pipes, in the factory, before they fit the Sump Pan"?
I still don't get it how the HEUI system could operate with 0 oil pressure. The oil pump was sucking a lot of air. How was the oil getting to the HEUI pump?
Interesting Find, Josh. I had an Allis Chalmers engine I rebuilt years ago that ran great on the Dyno, sent it back to the customer and he was plowing with the tractor, when he idled it down at the end of the field it would turn on the low oil pressure light. We brought it back in and pulled the oil pan. The crank driven oil pump, we installed new gears / shafts and used the original gear. The gear was a press fit. It was spinning on the new shafts. We installed a new oil pump and checked some bearings, no problems since. Closest I came to losing an engine. Thanks for the Videos.
Exact thing happened years ago on my 68' Mustang. Brand new rebuilt 289, bolts for the pick up backed out. Luckily I was able to fix it on the side of the road. That day was the day I learned the importance of Lok-tite!
Thank you Josh for the shout out. The video a great learning experience. So strange. I am happy to share my experience and pass on the knowledge. Cheers man. 👊🔧🔩👊👍💪👊
Air is a terrible lubricant, I have found after extensive study and many failures resulting in melted things. I mean unless that’s what you are going for; then success!
We had an intern doing an oil pump on a D6 w/ one of our techs. He slapped the pan back up on Friday but Monday had to go back to school. Tech fires it up and had no oil pressure. Dropped the pan and pump and he had left a blue plug in the pickup port.
@@SuperSecretSquirell the worst thing is when you tell a younger tech something and they completely ignore your advise. Like the fuel connector retaining nuts on isl cummins MUST be torqued 41 # everytime you remove a fuel line.... Watching them figure out why they have low fuel pressure for a whole week after ignoring your advice ... priceless
How much did it cost to tighten bolts? There is a lot to assemblying and engine. Even the most experienced mechanics need to double check their work. Mistakes happen. Yes they dodged a bullet on this one. Very good job diagnosing this. It taxed your skills but it's good to have a tough one once in a while. Keeps us human.
I have seen this issue before if ya ever run into this again over fill the crankcase to verify that's the issue before ya even drop the pan. i did that to a D6 on a pile of chicken crap out of desperation and I learned something so i am sharing. good luck JOSH keep going man.
I had sorta the same thing happen with a big block Chevy engine I built for my chevelle. I was told to weld the pickup tube to the pump and I didn’t listen because it fit so tight. I started it up and I made it a quarter of a mile down the street when I lost all oil pressure. Well as I was moving I swung the wheel from side to side and to my amazement the oil pressure jumped each time. The pickup had fallen off but the sloshing oil was enough to get me back home where I took the pickup out of the pan and welded a new one in with a brace, no more problem.
Dealer did a big service on my Toyota D4D diesel just before I bought it, I noticed it was a bit slow to pick up oil pressure so not knowing any of the history I pulled the sump pan, oil pickup was good but the disposable metal crush gasket where the pickup meets the pump had obviously been reused and was sucking air, it did pick up pressure but took a few seconds. Replaced it with a $12 AUD genuine part (and it even came with a note on torque settings and it was only single use) and bang instant oil pressure hot or cold. I dropped a couple of caps off to have a look and there wasn't anything nasty going on but there are mechanics and there are mechanics.....
Great job! Love to see fellow 7 liters! Yep, my guy told me that if my HEUI pump "failed" (oil pressure) then it wouldn't run so it's something to remember regarding the HEUI pressure/engine oil pressure as being not a solid issue but rather a distinct difference. We change it at or before 250 hrs every month religiously! Cheers!
I always tell the younger guys to always double check your torque and torque stripe everything crucial. If you have the pan off to reseal it it takes no time to check torque of pickup tube bolts and give a quick look to make sure everything looks ok and check the oil pan for debris and oil
Yep, have to put that dot of paint on them when torqued. It is so easy to miss something but when you do a final inspection hopefully you catch no paint and investigate.
I had a suspicion that it had something to do with the oil pickup tube. Once the oil warmed up it flowed better past the obstruction or the lack of suction. Luckily some oil was flowing, albeit it being oil foam.
Wonder if the dealership has realized how much work you're going to steal from them yet, if you can find enough work to stay busy, your going to be happy to be self employed, God bless you
I'm thinking they won't be using that engine rebuilder again or if it's an employee having a long chat with them about checking your work. Keep the good stuff coming.
I had a VW with low oil pressure light come on. The gasket on the pickup tube was so hard from heat it was pulling in air. Replaced the gasket and had good oil pressure since.
Heui needs oil flow as long as it can flow up to the reservoir, itll be able to build huei pressure. Had a 6.0 that had a bad check valve in the oil filter housing, had 1 psi of oil pressure but the injectors were firing and hpop built plenty of pressure.
One of the first things I've learned after a "few" years working on cars, the absolute first question I always ask, "what was done in the past" by other people before me?
Only problem with that question is the Answer may be as incomplete as the previous repair. Leaving you with a perfectly good question with a doutfull answer. I always start at the start and never assume the other bloke has done every thing . cheers,
Had a Cummins that was slow to build oil pressure and filter was never full, which led me to believe it was sucking air. Found pickup tube cracked at flange.
I’m guessing when the customer picked it up and found out what the problem was they said something like “Ok! Two bolts tightened. What do I owe you? $50 big ones cover that?”
Using logic and understanding the system. I still don't understand how the injection took place, minimally the air should have made foam and not allowed the compression to happen. Anyway good going getting it to show pressure. ben/ michigan
I asked a WTI instructor in fuel systems class a question about HEUI engines not having engine oil pressure. Can it start and run. All i got was smart ass remark but no answer. " that would be that last of your problems if it started". 🤦♂️ legit question come on.
i guess the guy that built that engine had a brain fart huh 😁 lucky it didn't wipe out any bearings with it sucking air like that and going through the system. But then again... if it is picking up any oil the engine will run quite a while with the oil film that does get on the bearings. Ever seen those videos where guys drain out the oil and run them dry just to see how long it takes to lock up? I saw slick 50 do a test like that once and the engine ran quite a long time before it locked down (on a test engine w/o their product in it). But yeah, these guys were VERY lucky no damage occurred (that you know of), without tearing the engine down and examining everything you won't know for sure. Yep, no metal in the oil filter was a good sign all is well so no worries. Nice find there Josh 👍
Great Job Josh!! Are you still living in Idaho? The last time I commented I was in Michigan but I'm commenting from Ghana today. Thank you and keep up the great work!
If the pump's body were cast iron or steel I would weld the pickup tube to the pump for insurance, like people do to the small block and big block Chevys.

Forest Gump never said that. He did however correctly say that the 4jj1 is a far better engine.
@@philmckrakin6752 Yeah, mechanics go broke if they specialize in a 4JJ1, huh?
@@delawarecop pretty sure the performance shops go ok. Putting out unreal figures out of them.
Better to pay someone a grand to find two bolts loose, than to have an engine fail from 2 bolts being loose lol
Thats why I call people like him when things are not right
Absolutely. An engine like that is 30k IF you have a good core...
You saved this customer an engine. Good job. They need to give you a bonus on this repair.
Calling in the expert to fix something stupid, but without the fix it would have been junk within a day, glad to see the engine survived that one
This is a fine example of checking the simple things first
Your getting that customer base building up quick
Whew! Gladly this engine escaped your Destruction of the Week mentions! Superb Diagnosis, Josh!

When you said a new engine, I thought cracked tube, wasn't expecting it to be lose. Easy enough fix.

Thanks again!
Ran into that before on several engines. Bad orings or cracked pickup tubes. Good find.
Josh, excellent diagnosis. Engines need oil as a lubricant not air😂
Nice simple fix, no parts required. Alway a good idea to go after the simple things first
I love the rebar door handle that's a pretty custom touch.
Thought only I caught that
Air is a terrible lubricant, I have found after extensive study and many failures resulting in melted things. I mean unless that’s what you are going for; then success!
Everyone deserves an easy one from time to time. My granddaughter drove her Malibu home with the "oil light" on. Only once😢
I loved the screaming goat when you showed no psi on the guage
Wooooooooow. Amazing how such a simple issue caused a major problem. Also that oil pan drop was beautiful, no sealant breaking or hammers needed!
I ALMOST did that to some hydraulic motor with the snap ring behind a lip seal. Something just felt wrong, removed seal and bam snap ring!
At least they put the pickup tube on. One of the techs I work with just slammed the pan up and sent it with no tube.
That’s not a tech that’s a parts monkey.
Trying to be fast can do that..a slightly lower efficiency with no comebacks is better than the shop eating a $50,000 engine
We had an intern doing an oil pump on a D6 w/ one of our techs. He slapped the pan back up on Friday but Monday had to go back to school. Tech fires it up and had no oil pressure. Dropped the pan and pump and he had left a blue plug in the pickup port.

from my experience, it's much easier installing the oil pan without the pick up tube in the way.

Lucky to caught it in time. Could have been worse if they ignored it much longer.
Love your videos Josh 😊🏴
I’m guessing when the customer picked it up and found out what the problem was they said something like “Ok! Two bolts tightened. What do I owe you? $50 big ones cover that?”
Nice find
He should buy a lottery ticket, it doesn't take long to damage spinning parts without good oil supply.
Those are good jobs to get
Using logic and understanding the system. I still don't understand how the injection took place, minimally the air should have made foam and not allowed the compression to happen. Anyway good going getting it to show pressure. ben/ michigan

Great 👍 job, got lucky!❤
Oil pickup bolts needed safety wired, IMO. Nice find tho' ! 🙂
Great job keep up the great videos
Lucky they didnt run it too long, it would not have liked the starving oil pump

From Nick Ayivor from London England UK 🇬🇧 ⏰️ 7:16PM Good Evening
I did not know those engines could run without oil pressure... shows what i know
A Boss!
Wait, so how did it run then ? You would think there wouldn’t be enough low side pressure to feed the high side pump.
I asked a WTI instructor in fuel systems class a question about HEUI engines not having engine oil pressure. Can it start and run. All i got was smart ass remark but no answer. " that would be that last of your problems if it started". 🤦♂️ legit question come on.

Yep, no metal in the oil filter was a good sign all is well so no worries.
Nice find there Josh 👍
Wow. Rings never went dry ? Had enough oil flow to the mains
How lucky for them 🤯🍺
Nice
Good video
Josh--do jake brakes shorten a diesel engine's life?
So cool❤
metal can not be moved if no oil flow, on the next oil change the filter needs rechecked, if it makes it that long.
But the customer said it built oil pressure once warmed up, so probably it didn't run that long dry
Looka that! 40 PSIIIIIIIIIIII.
Great Job Josh!! Are you still living in Idaho? The last time I commented I was in Michigan but I'm commenting from Ghana today. Thank you and keep up the great work!
If the pump's body were cast iron or steel I would weld the pickup tube to the pump for insurance, like people do to the small block and big block Chevys.
Dose the hi pressusre system have it own suction line
It could be that the pick up pipe was installed by Boeing people.
Lol
Loose bolts and nuts mean it's 5 O'clock somewhere!
