I have the head off my 1983 280ZX Turbo and will drop it off in Denver with a specialist later today. I need a couple of broken off exhaust studs removed, and may have him port the head for improved breathing. I'm NOT looking forward to putting it back together - it was a really difficult disassembly.
Praying that I don't have to do that anytime soon - good luck with it! The next major thing I need to address is the struts, suspension bushings (still original, and gettin' sloppy), and wheel bearings. The trans (5 speed from a 200sx) also developed a leak, and so I'll have to deal with that soon as well.
But for now- it's alive again! Had to go into the office today, and took it on the 66mi round trip voyage. I really missed driving it this past week. Seems like invariably, there is always one part that is a week away from me- in this case the water pump. Good news is that it was only $22 from NAPA
(wish my wife's car offered those kind of pleasant surprises!)
It was really fun working on it this time, since my older son (10yrs old) was out helping. He was handling the wrench when possible, scraping off old gaskets, making new ones (rtv), installing thermostat, hoses, slipping the new belts on, etc... After we were all done, I gave him the keys and let him fire it up. He had the biggest grin!!
