I was on my way there, when I stopped for gas, at the Chevron at No. Five Rd. and Steveston. When I started it up again.... rattle rattle rattle. Something broke. Called my GF, and she came with the M van, and towing equipment. Towed home.
Once home, took off a valve cover, to find a broken rocker stud. Woo hoo! Easy fix. Kind of a piss-off though, because I haven't beat on the motor yet, and it's still on single springs.
