Got the ba****d, that was an almighty struggle to get off, this is what it looked like after, and what it took to free it, with all my weight behind it

See there's a lesson to be learned. Old School. Start with a 22ft scaffolding pole and if it doesn't fit cut it down till it does. Avoids the interesting spanner combos.
Nice tool though.
As the filter apparently showed no signs of excessive installation force i'm curious as to how that filter had that much resistance in it. I'm very familiar with all the things that can and do contribute. But....?
This is turning into a better read/watch than BBC1 Bodyguard!!

Well, I did have a length of 3/4 galvanised water pipe that I usually use for such occasions, but it wouldn't fit over the handle of the ratchet, that and the fact the car is only up on axle stands means there isn't a lot of room for wielding things like that!, I have actually got a 3' 1/2"drive breaker bar, but there's no way that was going to be any good.
The next episode might be a while ,as I'm bugge***g of to the Canaries on thurs for a bit of a break.

The 30Nm quoted does seem high...? I’ve also read 25Nm. I’ve never torqued a filter, unlike wheel bolts. Might be right I spose?
What condition was the O ring when you got it off I wonder...!?

30NM is written on the filter, o ring looked fine on the old one, think I'll do some research on correct figure before fitting new one, don't know if @voicey has been following this, would very much appreciate your thoughts.

You just whack an old long screwdriver through the outer part of the filter... A small length of tubing over the handle for leverage and then your done!

30nm is a little higher than I would have thought but many common vehicles are in the 20-25 Nm range for oil filter.
Might just have been a problem with someone getting overzealous on fitting.

With respect Dave not a method I would recommend trying, especially on a Maserati with little access to the filter. I've used it myself in the past on old cars where there has been lots of space to turn the filter and have another stab with the screwdriver if necessary. Also there is a very good chance of tearing the canister, I know I've been there with the even bigger grief it causes.

Update, (but not a good one) Couldn't do any work today as let down by suppliers, so thought Id have a play as the weather was good, cleaned the filter from the bottom of oil tank, new oil filter fitted, and filled with 7 L of Shell's finest (as a start), NO CHANGE:too_sad: connected hose to breather from top of oil tank to avoid covering front of engine with oil again, and to start all appeared ok, even when I gave it some gas no sign of oil from the breather, exhaust was smoking a bit, but I hoped this might be residual oil being burnt off (fat chance), but as soon as temp climbed up then oil started coming out of the breather when engine revved :sad3::sad3::sad3:
So to summarise the symptoms are :- blue smoke from the exhaust, oil being forced out of the oil tank breather when temp is up, and engine revved, f***ed if I know:frusty6::frusty6:

I’m not familiar with the 4200 but it’s a dry dump so there will be a scavenge pump that takes oil from the bottom of the engine and pumps it to the tank and a delivery pump that takes oil from the tank to lubricate the engine.

I’d suggest two options:

If the pumps are on a common shaft the shaft seals may have failed to the delivery pump if feeding oil to the scavenge system.

The delivery pump is pumping a lower volume of oil than it was designed to.

Either way I’d suggest it may be a good idea to listen to Alfatwo and take it to an expert and I would get it transported there so you don’t get oil starvation.

Agreed it needs a professional looking at. If the scavenge pump isn't up to scratch it could allow crankcase pressure to build up and may give results like this. But I would suspect it's a pump issue.

I have Asked Dan, the Maserati master tech who was at FTech for help, as a matter of interest I have been scouring the parts diagrams on eurospares, and I cannot find two pumps, so unsure exactly how the system works on this car.

Looking at the parts diagrams it looks like the oil/water pump bolts to the sump and the scavenge part feeds oil to the oil to water cooler which then leads to the tank. A pipe takes oil from the tank to the delivery pump in the same casting which then feeds the engine. Looking at a photo of one I’d say the casting contains a weather pump and maybe 4 oil pumps all running on the same shaft.

Stupid question but you did drain both the tank and the sump?

There's info on here of the Project 4200 that I bought and put a new oil/water pump unit in 4 years ago on my driveway at home before bringing the car to NZ.
The pump was about £1400 if I remember and the factory had thousands in stock.

Thanks Phil, just read the entire thread of your project 4200, gulp.

Phil might be able to advise on what the issue could be here. Have you ruled out Piston ring or valve stem failure?
