Basically, a cautionary tale of how bad it can get - I know there are worse, but this one is mine ;-)
Here goes.
As I got it:
The intake valve covers, crankcase side covers, cam tensioner, sparkplugs, left camshaft endcap/tach cable, and top engine cover had already been taken off.
I got the right cam end cap/cover off with a rubber mallet and some wiggling:
The bearing had frozen to the shaft.
After excavating and removing the two nuts holding the head to the cylinders, I was ready to take off the top end.
Unfortunately, easier said than done. Keep in mind, I had sprayed the entire engine with Freeze-Off (compare to Kroil, PB-Blaster, etc.) a couple days ago, including copious amounts in the top end and sparkplug holes. Some light persuasion with the mallet and a bunch of wiggling and fighting later, it came up off the studs:
A little rusty and corroded, but the valves look intact - not too bad...
What about the cylinders?
Houston, we have a problem.
I'll be taking a shop-vac to it later to remove the free rust, trying to clean it up a little before applying more penetrating oil. Looks like that trick with the gear puller might be warranted.
Hope you're either enjoying this or grimacing! More to come...
