Pulled plenum, injector housings, breather box, alternator, AC compressor, oil cooler, AC condenser, radiator, fans, tensioner.
I've removed the secondary butterfly assemblies, and I'm going to have Marc Haibeck burn a chip. I'm not going to reinstall all of the under-plenum vacuum plumbing, it's just too old and dried out for me to want to gamble. Everything plastic is just brittle and itching to crack. I was surprised at how relatively simple the process of removing the secondaries was.
The Fluidyne radiator is still in excellent shape, so that goes back in. Some loose paint on the oil cooler, cleaned that up, got new lines to install for that too. The AC condenser looked to be original, so that's being replaced.
I have a new AC compressor and a rebuilt alternator on the way. New water pump will be going in. Old alternator was making some noise, and the AC compressor was seeping oil everywhere.
The one thing I've found so far which concerns me a little, is some areas of rust-colored staining of the block at the areas of cyls 7 and 8. I worry that this may be a sign of headgasket seepage, but the oil and coolant both look fine, and there's no white smoke from the exhaust... so I'm going to button it all back up and hope for the best.
More to come...
