So, I finally drove my Scout to a mechanic to get the upper end tapping checked out. Granted I've been driving it this way for years, Ziggy and Randy were both present when I bought it. I was prepared for the worst, but wanted to see if I could squeeze a little more life out of it or just fold the cards. Right off the bat he did a bore scope and found that the valves on #4 were closed and saw that a push rod had snapped and was sitting in the valley , he didn't check the other side but suspected something similar there since it's louder on that side. So, I've probably been running on 6 or 7 cylinders for quite a while . Now, I have another 304 that's been on a stand for a couple years and I think I'm ready to start the rebuild process. So, my question is, does anyone in HCB have rebuild experience? I want to do most of the work myself but when I get to the point of putting stuff back together I'd like to have another set of eyes to make sure I don't Fu@k something up. Also could use some advice before I start, like you should do "this" before you even consider taking on this project, or you'll definitely want to do "this" while you're in there. My plan so far is to drag it out into my driveway and de-grease the hell out of it before taking a pressure washer to it. Then dis-assemble and mark parts/take pics. I want to take the heads to A-line and have them decked, lapped and new valve seals (Chevy style umbrella?) I'd assume it would be a good idea to get new springs and rockers at that point. While they have the heads I can work on the bottom half, assuming the cylinder walls are in spec I'll probably just hone to get a good cross-hatch and do new rings and bearings. Also plan on re-doing all the freeze plugs too. Anyway, I'm planning to still drive the scout the way it is to the bash, lets see if she makes it!!
