Beautiful car!! I love the red stripe. I would take Dennis's advise and envite your mechanic over for a house call! It would be cheaper than the damage from the tow.
I agree with the other posts on the stuck pushrod theory. I had it happen on a new motor once. I used grease that was more like tar. Good luck!! Cary
