Ok your assembling you head and you put the stem seals on and valves and keepers; now you realized you forgot the base washers that the valves springs rest on. You dissasemble the valves carefully remove the seals and put in these washers now.....Do you replace the brand new seals or put them back in since they look perfect????????
Just wondering what you would do.

I can appreciate your concern. After all, who wants to go back in there again? If new seals were cheap and readily available, I might buy some new ones. More than likely, you would never have a problem with the other ones as they typically fail due to age rather than wear per se. If it were in my garage on a sunny afternoon and I wanted to ride that sucker, it would go back together with those seals.

9 times out of 10 those seals will leak since they are of fairly hard rubber the base (where the seal on the valve guides) will be stretched and wont seal properly

It's off an old yamaha that hardly gets riden so well see what happen I think they tried to just run those seals. I'll let you know if it ended up smoking. Thanks for the replies.

if the valve guide seals rip that easily, they were crap to begin with. I'd buy a different brand at that point.

in other words, I wouldn't sweat it at all. I've removed teh valves out of my head more times than I wish to recall and reinstalled without a problem.
