i am over having these ****king headers on my car. i dont know if its just my luck, consequences of having headers, the header brand, bad work done or what but i blew a 2nd exhaust gasket for the 2nd time in about a month in the exact same spot, a month after i got my stage 8's installed. im ready to trash these things and pee on them and reinstall stock exhaust manifolds

 

What brand are they? If it's on the mounting flange, it sounds like you have a warped flange.

 

I agree, take the side in question off and put a level on the flange side to see how out of whack it is.

A lot of times the weld job on the primary tubes is a big blob and needs to be ground flush, or, the flange is warped and needs to be flat again.

I have done this before with the help of a sidewalk and a BFH.

You can always get a nice new set of headers, I'm guessing they're Blowtech, Dynocrap or Summit brand?

 

they are edelbrock. the original owner installed em. i dont have the patience to get in the headers myself so a mechanic friend of mine does it at firestone for beer lol... maybe THATS the problem

 

 

Did you have them re-torqued?

 

they are stage 8 locking header fasteners

 

what gaskets are u using?

 

felpro 1444 and be done with it, tes gaskets suk there like paper

 

had metallic gaskets and that blew. then paper and that blew.

 

hmm.. i have the edelcrap tes headers they suck *** for peformance

but I have the 5.99 mrgasket header gaskets on there and standard bolts only have to tighten them up once in a while and ive had these on there for like 6K miles or somethin like that..

i think your flange is warped

 

possibly... ill have my buddy check it out when he re-does the gasket on tues. yes tues. have to wait a whole damn week =(

 

Definitely don't go with paper gaskets again after your friend checks the flange bro, please get copper or my personal favorite the "Dead Soft Aluminum" ones made by Percy.

They are well worth the extra coin for the aggravation you've obviously already experienced. I've ran these for years and have came back to loose / missing header bolts and it still sealed.

ill check em out bro... by the way... when are you coming to tear my engine block down? the motor is sitting waiting for you in my garage

 

We might just have to schedule a gtg out Ron's way soon

 

I'm in.

 

nice yeah i was thinking about that. a small bbq to do a small engine tear down. the teardown probably wont talk that long anyway.

i decided to take some vids of the car while i did the alternator.

heres just a clip of the exhaust from the rear
not too bad for an LG4

ur car sounds like a lawnmower with those busted gaskets.

 

lol hadnt thought of that, youre right it does haha

at least the second vid sounds better.

 

I use the SCE copper gaskets. They have always worked great for me. Do check the flange. If it is warped (depending on where) you might need to straighten it, or have it welded up and have it resurfaced.

Anytime your changing out gaskets because they are blowing it is usually one of three things. Either the exhaust system is hitting the ground and causing the bolts to loosen up and or compress the gaskets a bit further when it hits, since you said you have the stage * fasteners I do not think it is a loose bolt example, or the flange is warped.

Those are the only things that cause header gaskets to blow. Of coarse cheap paper gaskets can cause an issue too.

 

Dang it!~ I wish this thread would hve been around a couple weeks ago. I'm going with the TES gasket and a prayer. I'll be working on the car in an hour.
