NO OIL PRESSURE? No Problem for this engine.

[@AdeptApe]

Was surprised to see that it didn't have any metal in the oil filter, but they lucked out on this one. Thanks for watching.

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"?

[@982berti]

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?

[@philmckrakin6752]

Forest Gump never said that. He did however correctly say that the 4jj1 is a far better engine.

[@delawarecop]

[@douglasmayherjr.5733]

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.

[@Wandering_Horse]

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!

[@donmunro144]

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

[@smellfunny1864]

Ran into that before on several engines. Bad orings or cracked pickup tubes. Good find.

Wooooooooow. Amazing how such a simple issue caused a major problem. Also that oil pan drop was beautiful, no sealant breaking or hammers needed!

[@jimmcfee3488]

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.....

[@Safexscape]

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!

[@Charger1908]

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.

[@RobotsCanDoAnything]

Josh, excellent diagnosis. Engines need oil as a lubricant not air😂

[@markm0000]

[@WilliamLaakkonen]

Wow- surprised to learn that the HEUI system can run with zero oil pressure! Thanks for sharing Josh- learned a lot with this one.

[@smoki2515]

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.

[@timbertownusa1776]

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.

[@philiplieb575]

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.

[@markm0000]

That’s not a tech that’s a parts monkey.

[@Montana10mmAuto]

Trying to be fast can do that..a slightly lower efficiency with no comebacks is better than the shop eating a $50,000 engine

[@SuperSecretSquirell]

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.

[@Montana10mmAuto]

@@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

[@deanberolzheimer2658]

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

[@philipchesley9615]

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!

[@Uncle-Duncan-Shack]

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.

[@rondeichman]

My oil pressure for my CAT 3126B motor home is not good according to the gauge on the dash. The guy I bought it from swears up and down it's good as he had checked it with a hand held. I drove it 500 miles and over a few steep mountain passes getting it home and it ran strong while pulling a Jeep Wrangler. So being it's a HUEI engine it shouldn't run worth crap at 5 PSI. So maybe it's the sensor? Not sure where to start the process of elimination. Anyway, this video was really informative and explained a lot.

[@dimelopapii5948]

You are the man !!!

[@scottmacdougall2843]

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.

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

[@KD0LRG]

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.

[@jamesriordan3494]

[@DrewGangl]

Wait, so how did it run then ? You would think there wouldn’t be enough low side pressure to feed the high side pump.

[@swoopulater]

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 👍

[@monkeybarmonkeyman]

Oil pickup bolts needed safety wired, IMO. Nice find tho' ! 🙂

[@nicolem.792]

How lucky for them 🤯🍺

[@youtubeisawesome2487]

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
