Nope. That's what's left of a valve that snapped it's head off Did a world of damage to the piston, head and barrel
Actually, not so much. I had most of the parts in the cellar! Just as well. Race head, matched barrel and piston, 8 valves at £110 each... The only real parts cost are 8 valve guides at a little under £50 each.
The man's a legend in my eyes. More than happy to help out and stoically refused any form of reimbursement. He needs to be careful if we get him in a room together...he'll be pissed very quickly with the amount of beers he's owed!
nice! Yes, ti valves and (can't remember, but not bronze) special guides, needed because ti is harder on the guides than steel. Fortunately, I had a bunch of heads lying around. I'm putting new cams in this motor - after this, just one new set in my cellar...
They're ok if you change them regularly. But then, the cases are supposed to be changed at 400km, so I'm ahead if I don't have to swap them...
