VW T5 Too much oil

[GRW]

The 'butterfly' thing on the T5 intake sounds a bit like the ASO's (Air Shut Off), or 'Chalwyn' Valves fitted to some Genset engines (or any engine in a Zoned area of a Refinery, Chemical Plant or similar where explosive gasses could be leaked into the atmosphere and cause engine runaways).

The ASO's though (for safety, natch) had to be manually reset after being triggered (either by an event or by say testing the Emergency Stop buttons). I've been out to a couple of calls for the latter, when site staff have stopped an engine by the E-Stop, then not been able to get it re-started

No the oil level was fine. Read post 37.
Did you forget the smiley?

Mrclutch employees dont smile, they just pull your pants down!

Just to add to the guys problem he did another oil change today and this came out of the sump, hard plastic and metal bits .. oil level sensor fell apart ?

That looks more like bits of the plastic sump baffle. They can break up. The oil pump pickup sieve needs checking because smaller bits can get stuck in that and cause oil pressure problems. I have even heard tales of bits being dragged part way up the bores in extreme cases but I don't know if this is true. It must have the sump off for inspection now otherwise serious engine damage could occur.

This is what it looks like. https://www.ebay.co.uk/itm/112480545235

No. 21 below. VW calls it a 'surge lock' for some reason. Maybe translation.

That or a good endoscope? But, whatever it is, it most certainly needs clearing out (and replacing?)

Filling with too much oil will smash that ‘sump baffle’.

It's a terminology thing.
It 'locks' oil surges* below crankshaft level.

*Surges in this context is basically the oil sloshing around due to G-forces aka braking/cornering.
And it's not really a baffle as such, as it doesn't restrict sloshing, it simply stops the sloshes from going upwards and being hit by the crankshaft.

Thanks all, it was indeed the baffle or surge lock, it might cure things with a new one and a good clean up...

Guessing there are/were metal tags on that thing?

Those baffles were hard to find, even in a main dealer. Some engine places, localy to me use to keep spares.

Yes i think where the bolts went through, it explains the bits of metal.
