central52 Posted November 24, 2008 Report Share Posted November 24, 2008 I took my 47 Plymouth out for the weekly exercise run. When I started going in first gear, there was a metallic slapping sound coming from the engine compartment, like the fan was hitting on something, then a whirring sound. Shifted to second, sound went away, then came back. Same when in third gear. Ran fine with and without that sound. Drove around the block, and then went into my driveway, popped the hood with engine running and no slapping and whirring sound. Everything looks o.k. Engine purring nicely. Drove it again, and the slapping and whirring sounds came again, intermittenly. A friend thinks it might be the driveshaft and suggested I jack up the back, put it on blocks and run it in gear to see what's up. And ideas?
