...finished the K2 engine
Last time I could not finish it, the threads from the cam tower came up and I
had no helicoils left.
Looking good Georg!
I sent my K2 head off for bead blasting yesterday, the rest of my engine looks like new so I couldn't live with the old flaking paint and baked on carbon and grease, so it'll look nice when I get it back in the next day or two.
I made a horrifying discovery yesterday, I cleaned up my slightly rusty valve springs in POR-15 tank cleaner, and I thought, "why not dunk my grotty valves in this stuff overnight?". Well, we used to soak our gas plugs from our assault rifles in Coke as the acid therein was great for removing carbon, so it all made sense to me.
When I got home from work I was delighted that the carbon was all gone, but not so happy to discover that the valve stems were no longer nice and smooth, but looked a little bit "chewed" about an inch or so above the base of the valve, and are now a sloppy fit in a good valve guide I used to gauge the clearance.
Oh well, luckily I've got a few spare sets of good used valves, so I pulled out another grotty set and soaked them in brake cleaner overnight, and checked them this morning, and they look nice and clean. I guess I'm still learning...........
