[mattyealam]

ohh thats lucky! could have been very bad!!!

hows the head?

172/182 have a habit of doing it apparantly...

any evidence of other valves touching? (wrong timing?)

You have Shricks don't you? I wonder if the timing was right?

 

[Willis]

I think Litchy had a similar thing happen when he had his Shricks...

I have cat 402 I was meant to have schricks that wat I paid for at tdf but they fitted 402 but that another story timing was spot on head is ok a few light marks but will go again

Seen it loads on earlier F4R's and also on K4M's I've seen one so bad it smashed the valve seats, send shrapnel back into the inlet manifold, and it was sucked into all the other cylinders so wrote the whole thing off, also seen one smash right the way through the center of a piston and damage the con-rod


What valves have you purchased?
Was that you on the phone yesterday morning? can't be 2 people in one weekend I imagine
