Mains bolts have been ground off in-situ, lol. They made a perfect grinding paste resulting in a new oil pump and the bearing damage. Yep the dodgy gasket will reduce the oil flow. The customer knows he dropped a clanger, that's why he's not blaming you.

[@g0fvt]

I am not wise enough to know, but years ago we ran an Essex V6 in a light car with a front well sump, under hard acceleration it would briefly lose oil pressure. After one too many hard launches from the traffic lights the engine started to knock, it did nothing like this carnage. (We made a baffled sump when we fixed it). I realise this engine had a home made pump gasket but chances are it was in one piece when fitted. I think you are right on the money, the swarf from the grinding did the pump in. It would be interesting to know if the original oil pump was damaged too. You have to wonder too whether the remote oil filter assembly was contaminated when it was fitted. A shallow sump on a high revving engine may not be too clever if it has no windage tray and the pickup might have been far from optimal, a shallow sump with a stock pickup will encourage it to pickup crap that would otherwise sit in the bottom of the sump. Was the sump also "clearanced" with a grinder at the last minute? TBH I think there are too many unknowns to reasonably uphold a warranty claim, the wrong viscosity oil is the least of the problems. IMHO you can give a bit of "goodwill" but this engine was damaged by subsequent work, not by the original build......

[@adolfshitler]

[@eatsinabeat]

I worked in a machine shop for many years, with each reworked engine we supplied a sheet with running in instructions, the oil to use 'depending' on the engines application & supplied the oil, the onus is then the customer's to follow the instructions to the letter, and if not that was on their head, we also marked all sump & head bolts to deter tampering, and if the markings was found to be disturbed, warranty null and void, it's a minefield now and the reason we sold the business.

[@timothybayliss6680]

In the U.k. And the U.S. You couldnt void a warranty with taper indicating fasteners, not legally. There is the Magnusson moss act in the states and the consumer protection act in the uk. You could try and if the warranty claim was valid and the customer took you to court you would have to show how manipulating the hardware caused the issue. When the customer wins their case, like i said its a valid warranty claim, not only would you have to fulfil all warranty clauses but pay court fees and legal costs of the plaintiff. Even the stickers on consumer electronics that indicate manipulation have no value in court. A, it isnt 100% reliable B, there are nondestructive methods to open electronics C, the sticker doesnt affect functionality. Simply opening something does not break it and the courts in the US and UK have acknowledged this.

@@eatsinabeat the last time i had an engine "built" by a shop it pitched a keeper and twisted the oil pump drive during break in. Its probably a good thing it stopped making oil pressure because i shut it down right away. I took the pan off and found a keeper in the bottom. How well do you think things would have gone for the shop if when i walked in with a picture if the valvespring with only one keeper on it and a twisted pump drive and keeper in my hand they told me that because i took the pan off that they werent going to warranty the build? Whats is my responsibility here? It stops making oil pressure so i take it out of the vehicle and return the assembly to the shop? How much of my time do i have to invest? Installing the heads isnt terribly difficult but i cant remove the unit that has a malfunction without voiding the warranty either? Even the inclusion of tamper indicators is potentially a violation of consumer protection act because it assumes that warranty protection is validated based on something that isnt causal to the failure. You make a claim that its Sunday morning Jim that is the one thats going to damage the package through inept modification. That fictional person isnt the customer base of a machine shop of this caliber. Most people involved in the hobby or profession arent grinding mains hardware to fit a pan. Most people that do this and would use this shop for service would know how to swap a cylinder head or pan without causing malfeasance. The evidence of this is the lack of spurious warranty claims.

[@Andy-qo6rq]

(1) I would ask the customer who did the grinding (2) also who replaced the oils pump as the gasket has blocking the flow of oil restricting the pressure so changing the pump and leaving the old gasket didn’t sort anything out. (3) who did all this work invalidated your warranty. (4) but as we have the engine in bits we can sort out the problem that’s occurred but in doing so do not accept any liability for damage caused by a third party. Great video it’s nice to see the engines coming in with these problems that have been worked on by so called mechanics. The customer has cocked up but to Embarrassed to admit it. 👍

As has been said before, MAKE SURE that a full disclaimer is included in both the estimate for the work, and subsequent bill, as you cannot be responsible for owner's installation, treatment & maintenance of your engines.

I had an oil pressure problem on a v6 engine from an 1986 oldsmobile, it was modified for a jeep install, it turned out to be the thickness of the gasket being increased and the sump being elongated.

Great video. There is a difference between oil pressure and volume . No worries with pressure but suffering from lack of volume Wrong pan will suffocate the pump

[@matthewq4b]

There is not really a difference. Pressure is an effect of volume. If you have insufficient volume you will never achieve adequate pressure. Pressure is the effect of restriction against the volume of the liquid being moved. Lower the volume and you lower the pressure. Increase the volume and you increase the pressure. Change the viscosity of the liquid and you have to change the volume being moved to maintain the same pressure. Either increase the volume for a thinner liquid or decrease for a thicker liquid. The preceding applies to loss lubrication systems such as the oiling system in an engine. Closed systems the preceding may not apply.

As the engine guy said, “it’s not how often you run without oil, it’s how fast it makes pressure again.” (Basically how long before a big ends run dry) So you are spot on with dry sump, I did it to my Rover V8 and it is the right thing offroad. It sat at 28 to 40 psi all day no matter what stupid angle we had it Idling at. Basically the customer tried some tricks and they didn’t work out. (And the outcome seen appears to match the modifications mentioned) (as a weird engineering note; ironically you are better with a narrow sump that carries half the oil than wings that let it hide from the pickup)

[@stuartwagstaff6287]

I would guess it has been sucking air, either from the crap gasket or due to the poor sump design (most likely cause). Even an oil pump with that much damage will produce good enough oil pressure. The debris damage is consequential in my opinion. I work on off highway engines and anything that needs gradeability (if wet sump) needs / gets a deep well sump. Another thing that would worry me is that the oil pick up pipe has a minimum distance from the sump bottom, beyond that flow can be messed up. And these are usually set close to minimum by design. Messing with the sump clearance would not be good. High level assessment... Would i expect a on highway engine to survive in a off highway application. No!!!. Not without modification. And a shallow sump is not one of those modifications

[@vollandt]

On top of that, reducing the height of the nut can reduce the tension it is capable of effecting on the bearing caps by reducing the grip length, it gets worse if an angle grinder has been used and the nut hasn't been retorqued afterwards.

It had gone round with the oil/water mix inside the oil galleries/bearings and that filter got it all out.

Got the 2litre duratec with shortened sump. You have to cut the original oil pick up pipe which is plastic to make it fit.

If you go and buy a drill and unscrew one screw on it, then there goes it's warranty.

I have only done an engine rebuild once in my life (early 80s, VW Type II) and thanks to the Idiot Book it turned out fine. One minor boo-boo by breaking a piston ring but the parts shop helped me out with that. But the thing I knew even then as a novice is that every part, every tool and the work bench has to be spotless - you have to treat the process like surgery and eliminate contamination. To do something as monumentally stupid as to grind down bolts in situ just astounds me - metal dust and abrasive material will hide in every nook and cranny. Astounds me that someone working on an engine would do this. It would be like the doctor about to operate on your Granny picking his nose and scratching his arse before making the first cut.

Isn't it amazing that anything the customer did couldn't possibly have caused any of their problems?

[@garym1550]

Just tell him that you are sorry for his misfortune and how much it will cost him to make the engine right.

[@boosthit811]

The customer should run a mechanical oil pressure guage and also log oil pressure on ecu. Another bodge with the gasket and all the silicon, plus grinding the studs🤦‍♂️

[@thedon7536]

Good video. Is there a way of doing a pressure when you will loose out most of the time. You can’t guarantee a stupid customer that has used or modified a gasket

[@acorndogs904]

Total crazy why do these people mess around with engines

[@keithrimmer3]

I've never seen a spun bearing due to particles they only spin through oil starvation and overheating I've pulled sumps off with an inch of carbon in them and big ends gone but never a spun one, the low pressure could be a relief valve faulty, 0w30 oil is like water when hot I don't like it at all you need high-pressure oil pumps to get the same protection with it 10 w 40 never had a problem with it, why was the pressure not checked when rebuilt the first time around, he said he wasn't happy with the oil pressure why keep driving it with low oil pressure numpty, the cooler will need cleaning out and all the pipes as well, Good advise DON'T GRIND INSIDE AN ENGINE FFS.

[@stevenbusk539]

You should only be supplying sealed engines with the sump fitted and ready to install. Then you can walk away confidently and if it's taken apart by the owner or third party for any reason, then you tell them to do one. By getting involved at all even to inspect an engine after an issue you open yourselves to some discussion of fault or blame. Supply sealed engines with the flywheel and sump on, and make it clear that if anything is removed or modified from the as supplied spec that it's the customers problem not yours.

Thats kind of what you get for tinkering. He literally fixed it until it was broken. There was nothing wrong with it. My Ford 4.0 has medium low pressure most of the time and it works just fine.

[@bbjunkie]

Looks like signs of rust on the crank webs, any chance the oil got contaminated with water and he flushed engine before bringing it in?
