bent titanium valves

Has anyone had any luck with staighting titanium valves? not from heat but piston contact, valves were new otherwise sure. just for spare heads . bent say .015-.025 moly stem coating flake off? are tools for that intended for stainless valves / heat only? thanks

 

NEVER try to straigten a tit.valve....it won't be nice..it will break..you can straighten the exh valves if they aren't tit.Dave

Yes you can
we did this years ago when we were poor
in fact Wizards Warehouse sells a tool to do this
we used a collet in a lathe and turn it slow by hand with dial indicator
use a brass bar to bump it and watch the indicator
never had one break doing it or after they were ground and run
you cant go after them like a trunk monkey hitting them with a hammer

 

Iam poor also but can't aford a broken valve..ask any manufacturs of valves they will also tell you to never do it on a tit. valve..and yes I use a valve straigting tool for my exh. valves..works great..Dave

 

valves

thanks guys, unless it was all thumbs up I wont chance it ither

 

The dragster I used to work on we straightened ti valves all the time just like John did. Doug

 

Well I have straighted mine at .010 to .020 bent at the head not on the stem . They sell a tool for it but i use a collet on my bridgeport with a gauge to read how much the head is bent ,bend them .030 at a time so don't go crazy on it. Also If bent .007-.005 just cut them .


Hope this helps!
