<![CDATA[The blurr loses a valve]]>Made one pass at the track today, on the top end the car just fell on it's face so I let off and limped it back to the pits. Diagnosis at the track was no compression in cylinder #4. I got home tonite and pulled the valve cover and discovered the culprit. Either 1. the valve shim got spit out and then broke or 2. the valve shim broke and then got spit out. :icon_puke_r: So anyway the shim piece got wedged under the cam and smashed the alum part of the head enough that the lifter got stuck down. Hopefully the valve didn't hit the piston. No idea why this happened, was only spinning 8200rpm, have crower valve springs, etc. Just a fluke I guess.

chipped cam and smashed alum around the lifter:

Part of the shim that I've found so far:

Thanks for letting me use your air compressor, i woulda been screwed without it.

You all can look forward to some really fast times next year. I think both Dave and myself will get our cars "tuned" on the dyno for next year and come out swinging....not dicken around with crappy wideband units. 😞 🙂

Looks like Dave goes out with a 9.03 pass! ( not as bad as my 9.00 though last year)

So close to an 8! Looks like skip 8's and go for 7's next year. 🙂
