I'm having trouble with the idle air control IACV. Cleaned up whole sensor and surrounding area. Bought new idle air gasket from Carroll & roche and put it in. Turn engine on and idle is running way higher than normal, also white smoke and then idle drops right down like engine is struggling and check engine comes on with warning about idle air. So the stupid gasket is leaking coolant into the intake. Take the whole thing apart and buy loctite black gasket sealant and smother the area in it as well as putting the official gasket back in and try again, leaving it 24 hours to set. Then i try starting engine again and guess what - the same thing - white smoke, idle creeps higher towards 2k then drops right down and get idle air check engine light. So it looks like i won't be doing NCT on Monday Looks like IACV is broken/stuck and don't know why original gasket and loads of liquid gasket still leaks into intake - makes no sense. Anyone know how much a new IACV valve assembly costs?
