The Finnish Crew !!
Wicked ! You guys must have the most combined "sideways" mileage on this board !
Long Live Hannu Mikkola, Ari Vatanen, Pentti Arikkala, Timo Salinen, Simo Lampnien, Timo Makinen, Marku Alen, Juha Kankenen, Tommi Makinnen etc etc (Sorry for the bad spelling.... )
And what it used to be like back in the good old days when I was 7 years old, suitably demonstrated by Walter Rohrl (his mum was Finnish right ?
) :
Sorry for way off topic stuff !

Had another stab at it today.
I actually used the pliers from the boot toolkit that seemed to do the job fine. More oil was collecting in the cover after I cleaned it all out 8 days ago confirming that the O rings were leaking.
I was a bit more brutal with the twisting and turning. Your video gave me confidence. Before all I could see were £££ ($$$) !!! signs in front of my eyes in case I broke something.
Once out I could see more oil behind the solenoids, probably about a table spoons worth. Anyway, gave it all a clean up and removed the previous O rings. All apart from one looked OK. Changed them over, a little grease on them and they 'snicked' back in.
Screwed everything back in and was careful to ensure the gasket was all lined up.
16NM seems very tight for these little bolts.
Fired it up and it made a very disconcerting noise for about 5 seconds. Sounded like massive marbles in a bucket. Im guessing this is the pressure building back up. It died away and all seems fine. No codes, smooth idle etc.
Im going to pressure wash the oil from the belly pan tomorrow and see if any more oil collects from the possible leaking valve cover gaskets.
If it doesnt then I wont have them changed - naturally.
So VantaaM5 - I thank you kindly for the video, your a gent. If you were any closer I'd buy you a beer!cherrsagai
Kumaran - thanks for all your tips :15:

Great vids, many thanks, is that where brake cleaner needs to be sprayed to clean the solenoids up? I had it in mind that it needed to be sprayed actually inside the solenoids and then blown out with compressed air, at very, very low pressure I imagine. Is there any value in spraying it into the hole at the top?
I sprayed the solenoids while opening them. On those videos i was already spraying to clean them a little more. On me perspective you should not use brake cleaner, as it is a corrosive agent that may eat up the board and IC tracks. I use contact cleaner and vaseline for the finishing. IC boards contacts should be cleaned with vaseline.
My car has about 104.000kms. I am sure the vanos has not been checked before. The vanos seems to be working as there are no faults being displayed when checked with computer. But I beleive I should change the selonoid o-rings. What kind of advantage will I get when I change the o-rings? Does it meen the cam timing is not perfect when the o-rings are not replaced?
No, cam timing and O-rings are separate. Cam timing is the fundamental positioning of the cams, the O-rings affect how efficiently the VANOS can operate (the VANOS changes the cam timing to suit conditions), and there's some little filters in there too that degrade that are worth removing.

I found those with 'VANOS' and 'O rings'
