I got an MPfab o2 housing dump a while back but I installed it with the stock o2 housing gasket & realized that there is now a leak from the the downpipe side to the dump side since the stock gasket doesn't separate the 2 sides. It doesn't hurt anything but I'd like to find a replacement gasket to keep them completely separated like they are supposed to be. Anybody know where I could find one?

 

Clean the sealing surfaces and spray some copper spray gasket maker on both. Let dry and bolt up. Should seal just fine.

 

MAP sells nice ones that are normally used with their o2 dumps. Otherwise the only others I've seen are Megan's and they suck, basically just cardboard between 2 sheets of foil.

 

Cool. Thanx guys. I'll prolly hit MAPup cause I don't trust the gasket spray to fully seal. I was thinking bout using that already but was hopeing there was a better option.
