help with major problem
i removed the header to see how hard it was and then i reinstalled it...
now when ever i get above 3700 rpms i get this HORRIBLE fluttering sound...and at part throttle the car rocks bad like its boggin then getting power then bogging and getting power so on...and i have lost a lot of acceleration and power...
am i leaking up where the manifold meets the head??? im 99% sure its not the header/s-pipe connection... but i am unsure of the header to head connection...
I am NA with no major engine modifications...and i have no gauges...i wish i had a wideband and egt so i could see whats going on...
edit: it is barely even driveable unless at WOT and then it gets to 3700 and starts acting up...and i cant drive at WOT all the time...

Exhaust leak...did you make sure you tightened up all the bolts on the manifold? Did you use a gasket? Is the doughnut gasket still in place where the header connects to the s-pipe? Did you tighten the spring loaded bolts?

i re-used the stock gasket...the 2 piece metal one...and i put a little high-temp red gasket sealant...
the donut gasket was and i used a little of the red gasket sealant...
yes i tightened the spring bolts...

why??? no offense but i couldnt even begin to think that would make sense...
i mean the car isnt driven all that hard, has 35k, and the sound wasnt there at all until i removed the header...
i mean i guess it could be but i just cant see it what-so-ever...also i have NO overheating problems, no milky oil, no oil in coolant...

ok quick question....would a clogged cat possibly cause the exhaust pressure to build up and exceeds the gaskets ability to seal??
because i removed the header again and made sure to tighten the nuts in the proper order and im still having the problem and there is absolutely no sound below 3500 but above it sounds like major compressor surge but i am obviously NA...

Stat the car put your hand over the header and see if you feel a lot of air escaping. Alternatively, do you hear a lot of "putt putt" or sputtering. If all you did was remove the header i'm sure its an exhaust leak.

ok i decided to go out today and spray WD-40 anywhere and everywhere there was a seal...and i found the problem...
when i cranked the car and walked back up front what i discovered was a bubble bath forming at the bottom of the header at the donut gasket...i went back and revved the car and replicated the sound....when i went back to the front of the car, wa-la no more wd-40 around that seal and a bunch sprayed onto the block...
so now i have to get a new donut gasket... which should be cheaper than a head gasket or header gasket...

I think he was just joking about the head gasket He went back and edited it to exhaust manifold gasket
