nequamminor Posted July 8, 2008 Report Share Posted July 8, 2008 So I was playin around out in the country a couple nights ago, brought it up to 105 a couple times... It was just getting dark. I got to my friend's house and it almost smelled like plastic burning, but not quite. I popped the hood and the exhaust manifold, right on the driver's side corner where it bends around the front of the motor, was piping hot. Bright red hot. My engine bay was glowing red. I have also noticed after a certain point of playing in the car that the exhaust will change tone. It sounds like an exhaust leak. I assume its that manifold getting so hot it pulls away from the motor or whatever. Once it cools down its fine again, but I just thought it was very odd. Has anyone else had the problem before? Im sure I'd have to replace the manifold to fix that problem. How hard is that to do? TIA guys. Quote Link to comment Share on other sites More sharing options...

nequamminor Posted July 8, 2008 Author Report Share Posted July 8, 2008 Its a '95 Monte Carlo with the 3.4 DOHC. Sorry about that.. It really doesn't have to work very hard to get to 105. In any case though, its got a new catalytic converter. I think the cat is ok, although I'm not completely sure. Quote Link to comment Share on other sites More sharing options...

gp13069 Posted July 8, 2008 Report Share Posted July 8, 2008 you are most likley running lean which is not a good idea because it can lead to a host of problems like. melted pistion,burnt valve's,or even a cracked head or block or exhaust manfiold's. if i were to guess i would change fuel filter , then check fuel psi. i think it should be 35-40 to be safe . also change the air filter if it's bad . other than that unsure ?

nequamminor Posted July 8, 2008 Author Report Share Posted July 8, 2008 You guys don't think it's got anything to do with a bad manifold? Quote Link to comment Share on other sites More sharing options...
Night Fury Posted July 8, 2008 Report Share Posted July 8, 2008 What could go wrong with it other than cracking? Quote Link to comment Share on other sites More sharing options...
nequamminor Posted July 8, 2008 Author Report Share Posted July 8, 2008 No clue. I have a fuel filter as well for the car, I've just seen someone break the entire fuel line so I don't have very much confidence in replacing a filter that could be the original 200,000 mile filter.

Night Fury Posted July 8, 2008 Report Share Posted July 8, 2008 I can't get mine loose either, and I'm SURE it needs it. Quote Link to comment Share on other sites More sharing options...
gp13069 Posted July 9, 2008 Report Share Posted July 9, 2008 your filter should be a clip on one end and a hex head on the other. spray the fitting end with blaster for a few days before hand just the hex end you should be able to disconect the plastic cliped end being very careful not to snap the steal line. then with suitable wrench's hold both filter (the larger one) and the line fitting (smaller one ) make sure that the filter spins first and not the fitting it self then filter should spin off the small fitting and the fitting should stay on the line once this is done replace filter everty time you get an inspection that way you know that filter is good every year Quote Link to comment Share on other sites More sharing options...
rockfangd Posted July 9, 2008 Report Share Posted July 9, 2008 i wish mine went like that. it broke lol. all i did was cut the line and got a filter with a side for the clip and the other side for a hose and put in a section of 3/8 ji pressure F/I hose. If i had to say anything i would check the cat when the manifold is glowing. that is a weird one. very rare Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted July 9, 2008 Report Share Posted July 9, 2008 The car is running lean for sure...............this is a BAD thing. Could be a fucked up primary O2 sensor too. But fuel pressure is the FIRST thing to check. Quote Link to comment Share on other sites More sharing options...
