My passenger side exhaust manifold keeps leaking. the first time I put gaskets I got from the local speed shop which I was pretty sure the were the wrong ones. About a month after it blew ou and started leaking. So I went to NAPA and got replacement gaskets for it, this was about July or August. Now I notice a leak again. I just put on Slp runners on the car if that makes a difference. Does anybody know why this keeps happening?

 

Get some aluminum reusable ones that won't blow out, and maybe some locking bolts, that may help.

Not sure why you keep havin the problem though.

 

I'm too lazy to look in the book...
does "mr gasket" make copper ones for exaust manifolds?
I think I payed $35 for mine for the headers. I don't remember, spent too much...it just rolled together....

Not sure who makes them but copper ones are good too.

 

The ones I got from NAPA were metal I think aluminum. I dont know why it keeps happening either. Thanks for the help.

 

Then they should be reusable, most likely the bolts keep backing out, after you start the car up and let it cool, have you retightened the bolts? if not , do so.

 

well the package said no need for re-torque. I just assumed that a product worked like someone claims. it sounds like it is coming from the back flange (a.k.a. the bitch flange). I ll try it to see how long it lasts this time.
