First - thanks to Grumpy for his excellent how to guide....

Having spent some 3 hours yesterday renewing the rocker gasket (how do you get that crankshaft sensor off?? - saw a vertical tab but pressing it in or out didn't help get it off - had to leave it in place)...I'm a bit nervous about the cleaning the breather jet attached to the smaller breather pipe from the rocker cover.

If I squirt a load of carb cleaner down the pipe - won't this accomplish 75% of the job and hopefully free up the jet? (there was a very very small amount of suction when revving the engine). I'm just worried about access to this jet with my ham fingers - especially if I can't even get the crankshaft sensor off!

Which engine mate?

Sorry - it's the 2.0 GLS Ecotec...

Why do you need to remove the crankshaft sensor?  sure you're not referring to something else?

I would remove the ICV, throttle body and unscrew the nozzle.  The problem is that the gung gets baked hard by the coolant collar.

I don't know that carb cleaner just 'passing by' the baked-on, hard-as-anything stuff will do very much.

I've tried cleaning in-situ by mechanical means - hose off and then very gentle, careful application of a 'finger held' 1.6mm drill from both ends of the thing - and removal of the jet.  Removal method, although slow and laborious, at least allows you to see what you're achieving.

However...try the carb cleaner approach, and then try passing something of 1.6mm diameter through the jet from the throttle body end.  If it goes right through, you know it's clean enough!  

I think you may mean camshaft sensor, and I believe you have to undo a screw that's accesible when the top bit of the cambelt cover is removed.

Thanks for responses. I meant that if I can't even work out how to remove the crankshaft sensor when changing the rocker gaskets, then I don't stand much chance dismantling the breather jet and associated banjo joint etc!

The car is idling perfectly and hopefully the gasket change will sort the oil leak / oil submersing plugs issue. I'm just worried that there was only just perceptible suction from the breather pipe and this is suggested as a prelude to further rocker gasket problems...
