I totaly agree BUT only good engine practices should be detailed and not ones just to save money!

What secondhand valve guide on an 18year old 850 won`t have any wear?....especially a thrashed one which nobody would know of...

If the valves go side to side by too much then it does not matter what valve stems seals you put in they will be worn in miles and let the oil past which it look as though what has happened already.

So now surely the next step is new valve parts?

I have been there and got the T shirt and it don`t work successfully.....the money spent on another set of head bolts and gaskets and time you may as well spend on new valves/guides etc.

But that is only my own opinion!
