Have been really enjoying this also.Morning all, have been following this man's adventure,
It's an eye opener
Considering the location of that drive and access to it, I would of preferred a better design or a drive that could exceed the life of engine. A very small but important part that in itself will scrap the engineIt’s not unusual - many VAG engines had similar pump drive issues (at lower mileage). I fixed one of those myself.
Parts wear out and have a service life, if they were made to last for ever they would be more expensive (yes, even a Ferrari engine). 300k km doesn’t seem too shabby really.
What would be better is if manufacturers were to give the lifecycle details of their components, but they won’t, because people would consider it a warranty.
With much respect to M535, he did start at the wrong end, trying to remove the drive. I expect that by removing the pulley you can access it much more easily (it looks like these is a threaded hole for extraction).
That you would prefer a different design is not in doubt, but would you be willing to pay for it? This is the cost / benefit equation that faces all manufacturers. Ask me how I know.
Oh Dear just watched this and it's obvious that Stellantis has not been good for Maserati.
Makes you appreciate what works of art the 4.2 dry sump engines really are in my opinion.
Certainly did and repaired it.You had one which had a failed oil pump shaft too. So what’s the difference?
Certainly did and repaired it.
That was caused by the water pump leaking and rotting the splines on the shaft though.
It was a mess when I stripped it and it didn't damage the bottom end Zep.
Debatable the car had already been looked at by a Specialist in Kent who had condemned it.Mostly because it was caught in time, no?

I stripped it to find out and was able to repair it getting technical information from Autoshield as 10 years ago the information was not easy to find then.
You can do the 4200 pump Insitu once you have lifted the engine a bit.
Certainly lots to shift on a modern engine that's for sure.
He has already had the engine out once and done timing chains and turbos.Yeah, seen it now. I'd love a Trofeo Ghibli, but that engine design is *scary*. OTOH if they get to 180k + I should probably not worry too much.
From what I took away:
Most of the engine was actually in pretty good / good / excellent nick.
He was unlucky
The root cause of the issue is unknown.
The oil pump was going to fail at some point <guess> over next <100k miles
Those engines are designed to be built, not maintained!
