I've had a lifter sticking for a couple of months now. Been busy at work, and a heavy gig schedule; I figured I'd get around to it. I should've put new lifters in, anyway. No biggie, right? $40 in parts and an afternoon; just gotta wait for the weather to clear up. I dumped some engine cleaner into the oil last night. The clicking turned into knocking this morning, and the knocking turned into a jigsaw-caliber rattle right before the car died on the freeway, belching blue smoke out the passenger side exhaust. Oops. It does run, it just sounds like hell. EDIT: I'm hoping that nothing's too damaged, but it's not looking good at all; I can see that it's leaking oil right into the headers, and even a knucklehead like me knows that's not good. I drove it about four more miles, in to work, and will flatbed it down to my father-in-law's garage/workshop this weekend. I've got a line on a fresh 5.0 H.O. for a very decent price. I think I'll drop it in (take a day and port the heads), and bolt my dual-quad tunnel ram intake on, just to get running through the summer. In the process, I'll be able to tear into this twelve-letter-word and see what happened and what's salvageable. It's supposed to quit raining this afternoon and be nice for the next few weeks. Figures, huh? I'll probably be up and running right as the rain starts again.
