SamuraiFlash Posted March 7, 2011 Share Posted March 7, 2011 Hi all I need your help to find out whats wrong with my car Basically, I took her out today as it was a fine day, 5mins into my journey and suddenly i hear this loud noise, it sounded like a large crate was being dragged underneath my car. I panicked and pulled over, had a look underneath - nothing was there. Opened my bonnet and the sound from the engine bay didn't sound right. I went back in the car and I pressed on the accelerator slightly to about 1000rpm and the noise can only be described as a tractor was coming from underneath my engine bay. I drove her back home slowly as I wasnt too far, the car felt normal to me, however it was bloody load and i didnt dare go higher than 1,500rpm as at about 2k it was embarrassingly noisy. I'm thinking it's got something to do with my exhaust being loose somewhere, I hope. I say this as I was giving my car a wash and after the wash i thought I'd polish the back box of my Blitz nur spec exhaust system. I get the feeling that i probably applied a bit to much pressure and probably loosened something close to the engine and cause a leak in the system somewhere. Could this be the case or i there something worse that I should consider? Like a blow in the manifold? It's an NA-TT btw. Any help would be appreciated guys, I dont think I'll be able to sleep tonight Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted March 7, 2011 Share Posted March 7, 2011 I would imagine its exhaust related. Did your car have an undertray and does it currently have one? Just thinking it could have come loose, and caught the exhaust on its way out. Quote Link to comment Share on other sites More sharing options...
Josh Posted March 7, 2011 Share Posted March 7, 2011 (edited) Have you checked to see if you've knocked one of the rubber "rings" off the hanger and the exhaust's not wobbling about? Edited March 7, 2011 by Josh (see edit history) Quote Link to comment Share on other sites More sharing options...

Just thinking it could have come loose, and caught the exhaust on its way out. Hi rob, not sure if i have an undertray, i'll get it on a ramp tomorrow. I would have liked to take it to a mates place but its far too loud to be driving all that way. I live near a national tyre's, might just take it there if its defo an exhaust realted issue. The car sound croaky even on idle, when you have the bonnet open you can just tell by the noise that somethings not right. Have you checked to see if you've knocked one of the rubber "rings" off the hanger and the exhaust's not wobbling about? Hi Josh, The rubber rings are on the hanger and the back box is still in place. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted March 7, 2011 Share Posted March 7, 2011 Did you get the decats/restrictor ring fitted? Quote Link to comment Share on other sites More sharing options...
SamuraiFlash Posted March 7, 2011 Author Share Posted March 7, 2011 Did you get the decats/restrictor ring fitted? I only have a 2nd decat which was transferred over from my NA, the 1st cat is still in place. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted March 8, 2011 Share Posted March 8, 2011 Was it fitted recently? Are you seeing where im going with this? Quote Link to comment Share on other sites More sharing options...
SamuraiFlash Posted March 8, 2011 Author Share Posted March 8, 2011 Was it fitted recently? Are you seeing where im going with this? It was fitted when I had my Engine conversion done in October...you reckon the 2nd decat wasn't fitted properly onto the manifold? Quote Link to comment Share on other sites More sharing options...
Josh Posted March 8, 2011 Share Posted March 8, 2011 It was fitted when I had my Engine conversion done in October...you reckon the 2nd decat wasn't fitted properly onto the manifold? Have a check tomorrow and see if it may have come loose. Tighten the nuts and maybe get some exhaust gasket paste and whack it on there to see if that stops the noise/blowing.

RobSheffield Posted March 8, 2011 Share Posted March 8, 2011 I imagine they used some kinda paste, some of which could have blown out. I would be reluctant to take it to any national tyre/quickfit type place as they will just try to push to fit a new exhaust and generally bodge things up Quote Link to comment Share on other sites More sharing options...

I jsut hope it isn't something too serious, if it's just a little blow or a gasket's gone bad then I'll be at peace. Thank you. Quote Link to comment Share on other sites More sharing options...

Josh Posted March 8, 2011 Share Posted March 8, 2011 If you upload it to Youtube and it's before 9am then I'll have a listen on my phone before I start work and see if it sounds like it's blowing Quote Link to comment Share on other sites More sharing options...
Havard Posted March 8, 2011 Share Posted March 8, 2011 I was kidding Someone will take a listen and prove what iv said is wrong, happens all the time LOL..!! Sounds like a bodged fitment to me and then a big lump of paste has dropped out. Or the exhaust has corroded somewhere near the front/manifold. Just thinking, could the cat has disintegrated? H.

SamuraiFlash Posted March 8, 2011 Author Share Posted March 8, 2011 Had a proper look this morning with a mate and it looks like the blow is coming from where the exhaust manifold bolts to the head, so it's the manifold gasket that has gone and one of the bolts have come off Quote Link to comment Share on other sites More sharing options...
