i rang vauxhalls this morning regarding the 1100 revs I'm getting since I used carb cleaner (Wynn's) and they said that using carb cleaner, espeially lots of it can corrode the gaskett between the inlet manifold and the engine, (so I may have an air leak, my wife has the car at the moment so I cannot check it). They also said that the idling control valve has lubricants in it and carb cleaner can dry this out and make it stick. I need opinions on this one please especially regarding the gaskett on the manifold.
they said WD 40 should be enough to cure the idling control valve, does anyone have a price for a new inlet manifold/engine gasket? I hope thats all it will be, a sticking control valve
vauxhall are talking out of their back box mate. Ive used copious amounts on my old setup, and the inlet man gasket was fine when i swapped it a few weeks back. came off dry, except where it seals the coolant section on the drivers side.
Thanks mate, thats all I wanted to hear. There are cowboys all over the place, even within the trade. I don't know which is worse 'cowboys' or cowboys with a licence
the cleaner could only contact the outer edges around the port anyway, theres no way it could "eat" a gasket, plus carb cleaner evaporates quickly, as soon as you start the engine its gone in seconds.
Thanks Oddball - your my hero - I didn't think it would harm the engine or gaskett, it doesn't stay around long enough. So I hope its the idle control valve. I have the WD40 poised and ready for action the moment my wife steps out of the car.
yeah ive heard of that trick with the WD40, although you may have cleaned the valve it might need lubing now the cleaner has evaporated, should work ok.
I was driving to the shops when I had an idea, this usually happens in the middle of the night or while i'm on the toilet. But I thought Because the Wynn's had done such a marvellous job on cleaning the throttle body, I wondered if the previous owner had messed about with the screw for the throttle linkage and I thought now that the TB is nice and clean would the butterfly be a little off centre, in other wordss was too much air getting in? what with the butterfly being 'slightly' ajar and the air going through the ICV as well, it may have been more than it should have, especially now all the crap has been removed from behind the butterfly. Anyway I turned the screw a couple of times so that the butterfly did close a little more and hey presto, the revs dropped to a little under 850.
I know this story is a little drawn out but I wish to thank my parents and friends and anyone else that helped me solve this problem. It's such a relief when a problem is solved. Thanks guys for being there lmao lmao
i think the main flap is very very slightly ajar at rest.
