Thanks, everyone. It doesn’t sound like it’s missing (I would recognize this) but I’ll be pulling injectors in the next day or two and will check the idle.
Hope I didn’t smoke anything. It only red lined a couple of times for a few seconds, then came off of it pretty quickly. I don’t think I overheated it, but I’m sure I got it pretty darned hot. I’ll take it for a test drive in the morning when it’s stone cold with the cooling system SEALED. Lesson learned. Dan > On May 27, 2016, at 8:46 PM, Kaleb C.
