I honestly don't know. How does it compare to the other one?

Been about 6 years since I did this to my '58 Vectra. I do recall that it was MarkDTM who suggested it.

Presumably there was a reason why Opel fitted those gauzes originally. Why are we now removing them?

[Raeturbo]

Ford fit gauzes on the oil feed to the turbo on their infamous PSA engined cars too. They clog with sludge and have ruined many a turbo. Ok for filtering petrol (like we had in the carburettor days) but unless you’re spot on with oil changes they will cause problems. I always recommend removing them when I supply turbos for these. BMW had trouble with the early 320d when they had gauze  filters fitted to the camcover breathing system too. Of course good maintenance is the key, and as we know they are old school and were fitted to most of the really old stuff.

Mark can confirm, but I believe Vauxhall issued a service bulletin about them

[terry paget]

So reason for removal is risk of clogging causing oil starvation in poorly maintained engines. You see in pic that mine were not clogged. I suppose oil flow will be improved without them.

[Doctor Gollum]

The recent oil changes will have helped, as pretty much all the detritus is carbon build up from the oil around the engine. 

[terry paget]

Gauzes now removed. I see I can buy a new actuator for US$9.28 plus carriage, cheap enough, presumably including gauzes.
 
It's not clear to me why clogging of the gauzes should wreck the engine.  The valve timing would cease to vary, which would affect performance, bit like a sticky dual ram. Maybe oil supply to the head moving parts goes via the VVR actuators, so is reduced.

[Doctor Gollum]

Ask Fuse19 aka MarkDTM to explain it

[terry paget]

Fuse 19, please explain how clogged VVT mesh filters can wreck an Astra H 1.6 petrol engine.

I can see that with a turbo clogging of the oil intake filters could be disastrous, but not with variable valve timing actuators.

Found it...

Need to remove the black ones as well, which in your picture, are clearly collecting bits

[Doctor Gollum]

Reference Information / Bulletin Number
10-06-04-016

Model Year
2008-2011
Vehicle Line / Condition

Engine lack of power with DTCs P0011, P0014, P000A, P000B, P0012, P0015 or engine rattle noise

Do This
Remove the oil filters from the camshaft position actuator solenoid valves

Don't Do This
Don't replace the camshaft position actuator solenoid valves


Remove the inlet solenoid, plug the hole to stop excess oil spillage.
Remove the 2 orange filter bands and the black end cap filter from solenoid.
Refit solenoid

Same for exhaust solenoid if necessary.

.       If anything is rattling then it’s wearing too quickly somethings going to break,as said proper maintenance and correct oil is what’s needed.

Thanks Doc.
With respect, I think you may have misinterpreted the bulletin, it is poorly worded. The fault to be corrected is engine lack of power; this may be accompanied by a fault code, engine rattle, or both. I think if engine rattle alone was the sympton, it would have warranted a second bulletin.

[Doctor Gollum]

Does it, or does it not suffer from top end rattle?

Regardless, you need to also remove the black filters which your picture clearly shows to be contaminated.
