I am working on a 18.5 hp B&S OHV engine on a Craftsman tractor. It belongs to a relative. The pressed in valve guides keep working forward, to the point they interfere with the valves closing. This is the third time this has happened. The last time it was the exhaust valve guide. I didn't tear the engine down yet, to see if it is the same guide or not. Same symptoms as before, no compression and backfires. I have to go pick it up, and take it to my shop.
I drove them back in previously with a wood block and hammer. They seemed tight going back in, but apparently not tight enough.
What is the proper procedure to permanently lock these in place? Stake them, hi temp epoxy, set screw, or some other method?
