Thread: New Oil Pump

IMHO...

*Rather than bluntly shooting the OP down, I would have thought a constructive reply such as "interesting thought, although low oil pressure doesnt seem to be the cause of the rubbish Ford engine failures, it may help perhaps".

From where I sit...
*A small percentage fail due to the breaking of the oil pump housing.
*Most don't fail due to a broken crankshaft.
*Most fail are mid mileage engines, as in 160 - 250K.
*Most common failures are 2007 - 2009 models.
*Repeated "upgrades" during the life of the engine series doesnt seem to reflect better reliability.
*I've never changed out this many engines on a model due to failures.

I dont know why people get defensive over an engine that was obviously a rubbish design in the first place.
Lets hope and pray to the engine gods that the later versions were ACTUALLY improved and not just some spin doctoring.
Either way, these engines wont go down in history as having the worst reliability.

Well what do most fail from then?

Most failures are seized/spun bearings which sometimes breaks the crankshaft.

Which could be a lack of oil supply/pressure, poor fitment of bearing shell, problem with bearing material, oil contamination etc.

I’m going to hurry up to get to 250k kms. Just clocking 210k now MY08

Hopefully Dazza we never get to meet

So Dazza , have you found any transplanted territory engines have suffered crank failures due to the same poor build quality of the ford crankshaft ?

I only ask as it seems most transplanted engines are coming from later model territory's and this could indicate that Ford did address the issue. In saying that I still see the odd post about late D4 engines failing due to crank failures so maybe they didn't fix it.

Cheers Ean

Looking at the photo of the crank/bearings it appears the shells no longer have a locating "tit" to ensure it doesn't spin. Presumably they use some sort of glue to locate the shells which if so is a recipe for potential disaster. If the shells spin in the conrod/cap then it is all over within a few seconds. One wrecked engine is the result. Presumably done for 'cost cutting' reasons and gives me another reason and example why I hate Mechanical Engineers who design motor cars. History shows they have designed some absolutely disastrous engines and vehicles which any good mechanic would have been able to argue at design stage, just why it is a potential disaster.
