I am new to this forum and was wondering if anyone could help? My wife started our 2000 impala(3800) and it turned over a couple of times, backfired then blew a big hole in the upper intake manifold. I got the manifold off and noticed what I am pretty sure is gas pooled around the bolts for the lower intake manifold. It was dark in color and smelled like gas. Can anybody advise on causes of the backfire or the strange liquid?
