'85 12A Exhaust Issues

Romulan_7 · 11-16-2009, 02:59 AM

My car keeps burning out the collector gasket at the end of the exhaust manifold every couple of months. I'm thinking it's some kind of mixture issue, though I haven't gone through the effort to go chase it, so I'm not certain. I don't have any performance issues other than that, so I'd guess that the mixture wouldn't be far off if I'm right. As far as I know, the car has stock ports, and I know for sure it has a Nikki with the rat's nest intact, with stock ignition except for a couple of MSD coils. I run it on 87 octane without premix with Royal Purple 5W-30 in the sump.
