Valve guide oil seals,,, Your help is required.

The expertise on this forum never ceases to amaze. I have often wondered how valves with seals don't seize in the guides. Sometimes they do, evidently.

This was a bit common back in the day. After a head rebuild by the Oz distributors, I made the huge mistake of trying to run this engine work in on a bit of a trip. That resulted in 2 exhaust valves seizing and bending, lucky me, only 700ks from home in Bemboka. Apparently, I missed a gear change and over-revved it, OR nobody was sure how much clearance was needed for valves, and they made it too tight in the guides. Anyway, it became a nightmare retrieval. 6am bus to Canberra, train to Central in Sydney, taxi home, drive to get the bike trailer, leave to head back, arrive in Canberra to crazy mayhem at midnight, who knew Summer Nats car show was on, arrive at Bemboka at 2am, get bike and head back to Sydney, play dodgems with dozens of Kangaroo on the Fedral Hwy at 4am, start slapping my face to stay awake as a arrive in Sydney, arrive at Eades just as they opened, drop off bike, arrive home after 28hrs of contant travel and fall on my face. Absolutely stupidly dangerous, never to be repeated, well, a few weekend Ski trips happened pretty similarly. People die doing this dumb shit. BTW, I think Red adds seals to exhaust valves, I believe my 3c has them.
