Engine smoking...and I don't know why

[Tom Wesenberg]

Yep, and check the center main first because that's the one that usually goes first. My 29 Tudor sounded great at the swap meet, but after I bought it and drove it past 15 MPH, a deep knock started and it could also be felt and heard. My center babbit was completely gone.

If you need to do a rebuild, be sure to add counterweights to the crank.
