Y'wha''?
Each cylinder has its own inlet camshaft. Each pair of cylinders is fed from 2 of these - one inside the other. There are drive belts at both ends of the engine.

No it doesn't.
The inlet cam is split in half. One half driven from the normal cambelt end, the other half driven by a small belt driven by the back of the exhaust cam.

I'm in at BMW for the M140i's first service. Apparently my oil filter has fallen apart inside the housing when they have tried to remove it meaning my car needs an oil filter housing that they do not have in stock. Marvelous!
No loan cars available due to lots of DPF warranty work so I'm in an Astra SRi Turbo from Enterprise. Woo hoo! TBF it goes quite well and cruises the M/way fine enough so it'll do until 5pm tomorrow.
You realise if that was genuinely the case then you have filter element parts in your oil galleries? Generally it goes directly to the mains. Ask them to explain exactly what was done.
Just did a full set of mains and big ends after the customer was washing oil filters and it broke down after too many washes.
This is why I drive from my house to Bristol on any jobs I just don’t want to fight.
Dave!
The filter is a paper cylinder one that is accessed by unscrewing a cover and apparently the base of the paper filter gets stuck and breaks off meaning the only course of action is the remove and replace the whole filter housing assembly. The is also another inbuilt filter after the paper filter so stop anything getting through. the engine has not been started since they broke the paper filter.

That’s a really crap system, is this the same across a lot of BMWs ?
Mine is a cartridge type aswell and seals against a metal piece bonded to the element.

I think quality of filters from factory have been a bit rubbish. It's happened on quite a few first services. See link for details.

Hence my twin engine comment
I invite you to re-examine a VVC head when you get a moment. Yes, the other 'half' is driven by the back of the exhaust cam, but VVC works by adjusting the inlet cam duration (not just timing) and it does this by an elongated drive pulley on each end of the head. Each inlet cam effectively accelerates and decelerates over the course of one rotation. Thus, you couldn't have such a method working if each pair of valve cams were joined together. The only way it works is that the 'inner' (cylinders 2+3) camshaft in each case slides inside the 'outer camshaft (cylinders 1+4).
Here you go:
Approx 7 minutes in.
About 8:35 in you can see what I describe with one cam running inside the other.

Oh was that a real answer?! I thought we were still playing.

Backbox fell off the truck a while ago due to do metal fatigue and rust. Being a conscientious sort, I tidied up the remaining pipe with an angle grinder and carried on using it.
It actually sounds pretty good I think. A bit overbearing under load perhaps but nice enough when pootling about. The only real down side that I could see was that you do get gassed a bit when stuck in traffic.
Of course it does seem to make a lot of db though and that seems upset people a bit. Especially people on horses in narrow lanes. I can't actually hear them swear at me when I rumble and pop past them but the gesticulations are easily translated. Very angry indeed some of them.
A full stainless system is only £160.00 (of course it won't fit properly) so I've bought one in a bid to increase the peace.
Ruined tyre on the subaru due to puncture means that I now have mismatched tyres on the front axle. I'm just not going to ever look at them again and it should work out ok.

As a diesel mechanic I get a deep deep joy at watching cold start videos, not started in eleventy million years videos and fully mechanical diesels.
Get it working a bit, drain the oil, new diesel filter and it will last another 20 years, lovely thing.
When we move in 5 years or so I’ll be getting a MF35X tractor so I can just drive around whenever I’ve had a bad day
Dave!
It's all very alien to me, I've not worked on any diesel any more than having a quick look under the bonnet of a neighbours 320d
My confidence is growing in that it will start, run and stop ok, I didn't really want to break it and leave it stranded in a field.
I took it for a run round to the house to give it a quick sponge bath and get some of the dust, cobwebs and spider and bird poop off it before a little potter about down one of the fields.
It was last taxed for road use in 1994, but used around the land since but not a huge amount. It's showing 2000 hours on the clock. No idea if that's a lot or not much in the grand scheme of industrial diesels. Certainly seems to run very smooth and cleanly.

Interesting question! The Evinrude dealer here says a 5,000 hour life is about right for an outboard - based on that totally inapplicable comparison, 2,000 hours for a tractor engine sounds like nothing. Dave!?

The saga continues as the part didn't arrive today. Thankfully they have taken the Astra away and put me in a 530e Msport. It's a nice bus but feel like a right pudding after the M140i. It doesn't feel very quick and the 4 pot sounds like a sewing machine. It also has a tiny 40(ish) litre tank and has averaged 32mpg so far. It's really quiet, comfy and refined but I can't wait to get mine back on Thursday.

I wouldn’t even bother with a compression test till they had done 5000 hours. Considering 8000 hours is an entire year of running non stop then 2000 is nothing. Water in the fuel kills injectors so fuel filters and water drains need doing frequently. Good oil and let it warm through. Very simple animals when treated well. It’s why I love a nice mechanical donkey diesel.
Very jealous of the tractoring, as I’ve said before I enjoy driving my Defender more than any other vehicle so a tractor is a whole level above that again
Dave!

Tractor is ace Ian
Lupo needs the block honed, new valve guides, new valve seats and valves lapped in iirc from the conversation, circa £370. Good news is that original block is useable, bad news is the costs mount up quickly.

The rough running on The Compact seems to point towards vacuum leak(s). There's a whole load of hoses to check, and it means taking the top of the inlet manifold off to get at the injectors because they're attached to the vacuum system too. Anyone heard of "air shrouded injectors" ? I hadn't.

£370 sounds quite reasonable?
I need a new daily hack, and your posts have me keeping an eye on LupoGTi's on eBay now. I'm not bothering to look at the forum, I suspect everyone on there thinks they're all worth £15,000.

I hadn't ever seen or heard of them until I was poking about on mine and wondered why there were air hoses going to the injectors.
Don't know whether it's for emissions or powahh or both, wonder if the compact cup cars still keep the lines attach or remove and block up.
