Pull the plugs, and fill each cylinder with automatic transmission fluid or Marvel Mystery Oil. Leave it sit up to a week and it should break loose. The one that didn't was a 50's bathtub Nash a buddy and I bought. We soaked it, and soaked it, and soaked it. It didn't want to break, so we got mad and towed it about 50 miles per hour, popped the clutch and nothing. Ah, but then we made a U turn and came back @60 MPH, popped the clutch and va-voom she broke loose. Now I don't recommend you do this on today's roads but back then it wasn't a problem. Again, automatic transmission fluid or Marvel Mystery Oil and leave it soak at least 3 days, even pour in a little more here and there. Bill Borton |
