great, i can see fun times are ahead.
the previous owner already changed the gasket not that long ago.
the car is also running without a cat, and tends to backfire a bit, could it be possible that when this has happened the backpressure has forced the manifold gasket apart?
a long shot i know, but when it backfired under load last night, i could have sworn i saw a bright orange flash from under the bonnet. the car hasent been the same since...
just a theory...
