?? tapping/clapping from left exhaust pipe??
Ok. Back in business arm is healed up got stainless plate seven screws in right forearm. So started my 68 up (307) and seems to have a tap/clap coming from left exhaust tailpipe. I am not a motorhead by any stretch of the imagination, but can find my way around a engine, but I am stumped. Is it a valve issue, exhaust issue, both I don't know. When i started her up after sittin for a couple of months I fogged the neighborhood out (white smoke) which if I am right is a coolant issue, or rings, but if I remember correctly, the smoke should have a bluish hue to it. Both tailpipes spewing like crazy under choke. Turned off car cussed moaned smoked a cig and started her back up. Running rough and just puffed smoke about 12" out the pipes. So I decided to set the gap on points. Runs much better and smoother except for the before mentioned tap/clap which was there before the points setting. I plan on swappin engine out in spring as I am in the midst of nailing down a 454 to put in it. But want to drive it threw the winter just because she is bad *** and I likke it. So what's the problem???? Motor toast. Head gasket issues, valves or what? Appreciate and help. Thanks
