Hey gang,
Just checking in to share some progress! Project is going to take several days as tools/parts/discoveries happen, and I've made some progress.
The head came off in about 30 seconds with an assist from my wife. I don't know anyone does it by themselves.
Worked on the head first, getting it cleaned up top to bottom. The head shows evidence of having been milled before, so it won't be getting milled again. That said, the straight edge way able to lie flat without play, so no worries there. The only issue I'll have to tackle with the head will be some significant pitting at all of the ports where water would pass between the block and the head. Other that that, the head's good to go.
The block is slowly coming clean, too, but as you all know, just a very slow and tedious process, and there's more cleaning to be done. Of the cylinder walls I've seen, they are bright and unblemished (you're indeed seeing reflections in the pictures). It did look like some coolant was leaching into cylinders 8, 5, and 4, where the compression was also slightly lower. I got to cleaning the piston head with Scotchbrite and some brake clean.
Some other questions that have been asked:
- There was only ever blue smoke at start up, then white, then no smoke (my wife commented on this the other day before I got into the disassembly when I was driving the car around the neighborhood and she was out walking). It's never really smoked, other than some MAJOR rich running issues I had when I first got the car... Thankfully, that was sorted out.
- I never did a vacuum test on the valves, though I know that would've been a good practice. Plan at this point is to take each valve apart, clean/lap, check guides, verify valve stem length with the gauge, clean the lifters... basically recondition the valve train with what's in the engine and replace parts as needed.
Haven't dug into the valves yet. The tool I bought (a spring compression tool advertised by Briggs and Stratton) is fighting me - I just don't think it's beefy enough for this particular assignment. I've since purchased a different spring compression tool from eBay (one I found recommended in another thread on this topic).
That's where we stand! Won't make much more progress for the next day or so - taking the kids to MonsterJam in Greensboro! For now, it's a decent start I think. Thanks, all!
