Who carries ferrera valves? Is a stratched valveface salvagable?

crazypete · 07-30-2004, 11:25 AM

So I was porting my gt-40p's and went to go see if I could touch up the plug boss a bit with my dremel. For precautionary measures, I dropped in my 5000 series 1.85/1.55 ferrera valves to protect the seats. Well, the dremel slipped and now there's a decent gash across both valves (but the chamber somehow escaped any damage. Yes, I'm an idiot but the junk valves I had were either way too small to protect the seat or waaaay to big and wouldnt clear the plug boss.

I took them out, put them in a drill so they were spinning and touched the face of the valve to some 80 them 220 then 1000 grit sandpaper. So now theyre ok looking but maybe a few millimeters tinner and an eensy bit wavy but only on the face. The back of the valve is perfect and untouched.

Can I still use them?

I'd replace them but nobody seems to carry them in stock or list them on their websites

When you say "face" I'm assuming (we all know what that does! DOH!) that you mean the flat area facing the piston, and not the cone shaped backside in the heads. Right?

If this is the case you're fine, except for an all out race motor. Put her back together and run it. You won't even know there's something amiss on that cylinder. JMHO Good luck bro!

I figured that the combustion chamber side would be ok with a little wave but I would rather check to make sure.

I've since ground some old valves down to fit.

Thanks!

I would go ahead and use them, as long as there are no sharp edges on the scratch anymore it shouldn't develop any hot spots.
