dont start your truck. that gp will be embedded into the piston and will give you a hot spot..... it sucks but just do it right. do you have the shop manual i emailed everyone yet?
if not send me a pm with your email address.

fwiw if you ever run into this again or anyone else. needle nose vise grips and grab what you can and spray pb blaster down in the hole and let it soak for hours. then work that thing until it comes out.

sorry to hear the news.
