5.2 in a 68 Barracuda
Today, I got the heads dismantled and cleaned. Amazing how clean the heads are at 160K miles! I thought maybe I would go ahead and lap the valves after wire brushing them and cleaning the seats. Wow, that must be a forgotten process! None of the three generic auto parts stores have the manual lapping tool. So, I took a short piece of fuel line hose, cut the head off a 2" long bolt, inserted the bolt into the hose, put a clamp on both ends and I have a lapping tool! With the valve in the head, push the open end of the hose over the valve stem. Put the bolt end into the cordless drill. Tighten the clamp at the valve stem end to secure the hose. Then I put some rubbing compound on the valve seat and valve face and start the drill. I went forward and reverse to mimmic the old style lapping motion. Only thing is, the rubbing compound lasts about 2 nanoseconds. Guess I'll go to the box store tomorrow for lapping/grinding compound. If they have it. LOL
Also got the block cleaned up some. There is absolutely no noticeable wear on this engine block! How can an engine have 160K miles with no wear? Ain't like the old days!
Don't know about working on it tomorrow. It's supposed to be colder than a well diggers posterior here tomorrow. 7 degrees in the morning!
Let me attach pictures, then I'm going to hit the sack.
