SamGTi 0 Posted February 25, 2007 My car starts and immediately runs at about 2000 revs for about 20 secs and then slowly the revs fall, the engine splutters and then dies. I believe that this is most likely to be an air leak somewhere. Am I right? So, I have checked all the pipes and hoses and fittings and can't see any problems but I have noticed that there isn't much of a gasket between my inlet manifold and head. Should there be one? It's basically metal to metal. Could this be the cause of the air leak? Any help would be greatly appreciated! And I may be barking up the wrong tree, if so, tell me!

Richie-Van-GTi 71 2 Cars Posted February 25, 2007 start by fitting a gasket, then ensure the bolt is in that holds the oil filler neck and work backwards from there. It must be a massive air leak though as normally with air leaks the car will run but badly. Share this post Link to post Share on other sites
fletch 0 Posted February 25, 2007 Lack of gasket may mean the seal is poor and air may be leaking, although I would expect it to rev its nuts off. As Richie says try a gasket as the first step. Share this post Link to post Share on other sites
SamGTi 0 Posted February 25, 2007 It IS revving its nuts off for about 20secs but then slowly gets lower and dies! If it's not an air leak then what else could it be? Share this post Link to post Share on other sites

SamGTi 0 Posted February 27, 2007 (edited) What would I do without this forum?!? I replaced my inlet manifold but the car was still cutting out so after another search, I eventually found the problem. The bolt securing the filler neck to the manifold had come out! 14p later and the problem was fixed! So thanks Richie - you were right! Thanks for all your help (again!) and for those of you that shouted at me into doing a search - it worked in the end!

fletch 0 Posted February 27, 2007 Take it you mean you replaced the gasket not the whole manifold?! Share this post Link to post Share on other sites
lagonda 42 Posted February 27, 2007 Any one know just why Peugeot drilled right through for this particular bolt? As all the others are blind, were they just being perverse (surely not!). Could be cynical and see it as a deliberate "mistake" providing a nice little earner for the dealers. Share this post Link to post Share on other sites
Richie-Van-GTi 71 2 Cars Posted February 27, 2007 I think its drilled right through as its for holding plastics which are easy to crush through with a bolt. If it wasnt drilled right through and you did over tighten the bolt and crsuh the plastic then you potentially have a cracked plenum. Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted February 28, 2007 If it wasnt drilled right through and you did over tighten the bolt and crsuh the plastic then you potentially have a cracked plenum. Along with a chunk of aluminium in #1 inlet tract posiibly finding its way past a valve into the combustion chamber. Graham. Share this post Link to post Share on other sites
SamGTi 0 Posted February 28, 2007 Take it you mean you replaced the gasket not the whole manifold?! No, I haven't touched the gasket. It was just the bolt that holds the oil filler neck to the inlet manifold that had come off somehow so I simply put a new bolt in and everything is fine now!
