OH yeah! Great job Mo! Get some sticky tires and make yourself up some home made Caltracs and you will be knocking that time down lickety split!

 

dont burn out with the street tires and itll help some. just knock the dirt with a quick spin. street tires will get slick when they get hot. thay have alot of oil that comes out from heat

 

heres the mentioned spark plug. that cylinder is down 15 psi on its compression test. im going to do a leakdown test to see where the damage is.

 

Wow, crossing my fingers that everything is ok Bryant!

 

I'm pretty sure there's some damage. I'm hopeing it's just a valve but would not be suprised if it's a piston.

 

My first thought was a valve, but you're right it could be a piston, ring or ring land.

 

so did the tip of that SP break off because of detonation or did something phyisically touch it?

 

either detination or that cylinder went lean and the electrode got so hot it melted down.
