I don’t really know why you’re planning on rebuilding the whole shebang. From what I’ve gathered reading this thread, it’s just a head gasket. Take the head off, get it machined, put it back together with new gaskets. Rebuild the timing while your at it and it’ll cost (very roughly) $500 or so.
I hate to dash your hopes of rebuilding engines, but it’s gonna take more then that. For it to really work you’d have to be extremely familiar with more engines then just one, and even if you could succeed specializing with just one, you’d have to have experience with more then one scenario. Could you succeed doing something roughly along those lines? Yes, but it would take more like years of experience working on multiple 4.7s, if not multiple different types of engines.
I appreciate your words of wisdom!! Okay. I didn't know it'd be THAT cheap! With that said. How would I go about in recovering the refrigerant? So that it gives me more room to remove just the heads to send out to the shop?
