Car was running great, did need new battery, found that out for sure when it was cold. The only thing I can think is the block heater, which jr left on for a day got hot caused some gas vapor in the intake, and when he went to start it kaboom. Blew the entire ouside manifold off the inner portion. Will find out this weekend if I need a new intake. Ian do you have one in your shed? I dont think my luck could be that good.
