I have been posting about this problem on the Farmall site and have received some very good advice but I'm getting desperate so I'm posting it here too.
I have an F20 with a rebuilt head, new guides, springs, valves, seats, the works. When I first started the tractor up after putting it together it ran 10-15 minutes, then #1 exhaust valve would stick. After a cool down I could gently pry the valve back up and after a restart it would stick again in 10 minutes or so. I pulled the head and took it back to the machine shop. The valve was moderately tight in the guide and was galled on the bottom part of the stem where it exits and reenters the guide. On friday I picked it up from the machine shop but was in a hurry and didn't ask him what he did to solve the problem. Yesterday I put it back on the tractor and after starting the tractor it stuck within five minutes. Someone on the Farmall site sounded like he had this problem before with a bad new guide in the past. What do you think? I have been squirting oil on the valve stems while it ran hoping to get some lube down there but it didn't work. The guy who does the heads at this machine shop is competent, I am not questioning his abilities, he has done a ton of heads on all kinds of engines from the smallest to the biggest. The head is coming back off today and is headed back to the machine shop tomorrow but I would like to have some ideas to throw at him when I get there. Thanks

Today's Featured Article - On the Road with Dave Gohl: Auction Musings - by Dave Gohl. I was thinking the other day about all the auctions I've been to in the last few years. There've been many. Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
