overgrown Posted August 10, 2008 Report Share Posted August 10, 2008 Well i put some extractors on my 4k over the weekend, and since puttin them on the car will not idle. so fit the extractors i one of the emmision items had to be removed. it was the one that runs from the intake manifold to a emission thing with a vacume hose and then also attached to the exhaust manifold. since the extractors don't have removed this and i blocked the hole in the intake manifold. now i put new intake,exhaust gaskets on and the carbie gasket is in good nic, and everything was cleaned with a wire wheel before being put back together. so is there any emision gear that could effect the idle? or is the a leak in the intake gasket? just want to know before i take the manifolds off again.... sorry for the long post cheers matt Quote Link to comment Share on other sites More sharing options...
the Db king Posted August 10, 2008 Report Share Posted August 10, 2008 its probably something simple, like a vacume line off, leaking gasket, check to make sure there the wire with an ign feed goin to the carby if its a asian carby Quote Link to comment Share on other sites More sharing options...
Redwarf Posted August 10, 2008 Report Share Posted August 10, 2008 Have a look and see if your inlet manifold flange and extractor flange are the same thickness (there or there abouts.) I'd start there, because if the inlet isn't sealing, it'll run like a dog. Quote Link to comment Share on other sites More sharing options...
overgrown Posted August 10, 2008 Author Report Share Posted August 10, 2008 yea the flanges are slighly different sizes, i thought that might be the case, where would i take it to get machined down so the same size? once i have that it should be good? its does run like bit like a dogg, thanks for the quick answer! what vacume lines are vital for the running of the car? cheers matt Quote Link to comment Share on other sites More sharing options...

KE55PIG Posted December 26, 2009 Report Share Posted December 26, 2009 I'm Confussed why does it matter if there different thicknese ? aslong as they line up they wont intefear ? Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted December 26, 2009 Report Share Posted December 26, 2009 Because only the thick one will be squeezed up against the gasket. The thinner one won't be held tight & will leak easily. My Datsun ones were so different I glued a half washer onto the washer I had under the nut, so it squeezed both the same. Quote Link to comment Share on other sites More sharing options...
