This came to my attention on another site. It is a warning from Autodata about these engines not picking up oil through the pump after an oil change.
Here is the
Autodata link

So from what I understand from reading the site, you must not leave the drain plug off for more than 10 mins. But my understanding of draining the sump is that even with the oil drained out, sump plug in place, wouldn't oil still drain from the oil pump into the sump, as the sump has no oil in it. Or do they mean that you have only 10 mins to drain the oil, replace the sump plug and refill with oil? May be a two person job to change the oil. Bob

It's not written
well, the issue is with the oil pump loosing its prime and having a low ability to draw oil up and self prime.
They mean to drain for no longer than 10 minutes, then re-fill and kick it over ASAP.
Wont be a problem at a dealer, lucky if they let em drain for more than 2 minutes!
I'd be interested to know how the oil pressure holds out on these engines, if the pump is wearing out and the clearances are opening up, I'd expect that the oil pressure will be slowly degrading as
well.

Makes you wonder how they got oil pressure in the first place if the pump is so incapable.
People are going to be stuffed when the sump is off for some reason, or is that the engine which will be stuffed?
It sounds worse than a worn out 2H landcuiser engine.

Ross,
I agree with you. Although there is this tech bulletin out about the problem, I also wonder how they get oil pressure from new if this is the case. I have been told they have a guy who blows into the tappet cover to pressurise the sump on initial startup, and this stops the problem.
Engine problems related to this don't seem to be reported on
forum sites. So who knows.
Maybe some service people forgot to put oil in the engine before they started it. Good way to cover your arse. Guess that would never happen. LOL.
Time will tell.

When new the vane pump is probably OK, but in service it's flogging out. Probably due to some six sigma lean manufacturing genius bastardising the design or material specs.
Might pay to use an "anti drain back" oil filter with a
check valve on these motors.

amazing at what lengths there going to for better fuel consumption, chain driven oil pump, over gear driven,know what I would prefer!,,,But that's technology these days.,in the duratorq
camp.

Axle,
I had a "chain driven oil pump detroit engine" that was built in 1941. It served some of it's life as a stationary engine and was then went into an Alice dozer, I don't know how many times it was rebuilt. In 1982 I rebuilt that engine with the latest N series pistons. Guess what the old chain driven oil pump was not touched.
One person here in another post dismissed detroits as a cheap engine. I know that old engine with the chain driven oil pump, was still going in 1995.
Guess time will tell if these new engines are up to scratch.

Fair enough,..probably a very good heavy duty quality chain with a abundance of oil,...I would imagine the revs would have been down on a motor of that vintage as
well,...as you say time will tell with the new breed ,they may be fine, its a bugger if there not..lol.

No good for me. I remove plug, then make a cuppa while draining. Come back and get oil all over me from the oil filter. Wash that off grumbling all the time and put a new one in. Have a look at air filter and radiator. Make another cuppa. Light a smoke and yell at the kids who just kicked a ball under the car coming close to knocking the now very full oil container. Drag out the oil container, again grumbling when a drop of oil splashes out on the ground. Pour the old stuff into a container before the kids find it. Being very very careful not to spill.
Then put the plug back on. Fill her up.
Hard days work. Time for a nap.

You forgot to mention," after searching for the sump plug for an hr" !

Which fell into the oil catcher and you have to fish it out! Only to find the copper washer is still in there!
