Predictable is good [emoji41]
I do my servicing, check my vehicle and predict it’s good for another interval. [emoji23]

What was always unpredictable was how it would come back from someone else working on it.

We’ve shown that not to be the case as long as the NRV works. Maybe that’s a fail point maybe not.

the mann filter has a non return valve they say...

why would there be 2 ?

The actual paper filter is just a cartridge with a nipple plug on the bottom and a hole in the middle. There’s no gizmos or moving parts

If you look at it from a different angle, the filter is the media, cartridge and housing. A conventional spin-on is the same, it's just in a sealed all in one tin. The anti-drainback valve is usually a rubber skirt over the inlet holes.

Interesting you should say that.
I only know one owner personally, that guy had done over 500,000km when his engine let go.

And that was an early D3

So, 'twas about due for a bit of work anyway?


Still, one doesn't expect to have to spend big $ what would you be looking at $ wise $10 - 15,000?

Received the MANN oil filter today. The OD measured across the o-ring on the spigot was 11.1mm

Removed the MAHLE filter - oil had already drained to the level of the drain hole (which is meant to be plugged by the spigot). But was happy to see it was completely flooded above the anti-drain valve.

By the way - this is fresh new oil that is already black from less than 1 hour of running - just shows how much oil is left behind during an oil change.

The OD of the MAHLE filter o-ring was 10.8mm.

This difference is only a fraction of a mm but exactly what people reported on Lr-club.com.

The MANN filter locked in nice and firm when fitting. Will have to get a Ryco filter next time to compare.

Normal 4 secs for oil light to go off first time, and then on re-start goes out as engine is cranking. After the weekend will park the car up for a few days to see if there is any change with the oil light off time. 🤞🤞🤞🤞

Meanwhile some more photo’s.

First is the hole in the housing just below the rubber seal. When you open up the filter 4-5 turns this not only lifts the filter element up and out of the drain hole, but this small hole in the housing is also exposed and allows air in so it drains off.

Next is the blocked filter bypass. As Brad suspected it does appear to be in the top of the housing cover itself. Does not look to be serviceable.

The photo is difficult to see, but it does look like a match for a typical bypass valve, but would have to pull out to truly know.
