I have a mild 350 currently in my car that uses some oil, but runs strong. A few months ago, I started to notice that after turning off the key I would hear a little "poof" sound come out the exhaust. It doesn't seem loud enough to be a backfire and the engine doesn't seem to run-on. It is not a big deal because this engine is coming out next month for a new bullet, but it has me stumped. Any ideas?
