Ok well so far the head swap is alot longer away and it sucks just as i thought it would.
Anyway one cyclinder/piston has a nice small circle spot on the topish right part that is shiney. Then you can feel the normal buildup of carbon or whatever around that small circle.
Prob about 2-3 mils of buildup around it.
Not sure how/why it would be so clean on that one spot....also that one cyclinder is a much more brownish color almost all over compared to the others. I did try cleaning it off and the brown tarnish so to speak comes off fairly easy but it is alot more buildup i guess on this one compared to the others.
Any ideas? All spark plugs look normal and it's not the normal number 7 running lean.

 

does it look like its where one of the valves were coming down and ever so slightly tapping it? just throwing out ideas

 

That's my first thought too. What cam are you running?

 

thats all i can think of is something valve related.

TR224, IIRC

 

I'm running a TR220/112LSA the valve looks perfect and in no way has any differances compared to the others.
I'll try to get a couple pics of it if the camera has enough battery power.

 

Took some pics. The intake valve looks to have a little less buildup around the edges on it....compared to the others. Not sure really. Ideas.


Close up of valves.

 

And the pupsta!!!!

 

im assuming no damage to the piston or valve at all ?

did you ever run any seafoam, fuel treatment, octane boost, or any other chemical through it ?

 

That is what I am thinking. There is nothing that looks too outta the norm, how many miles on the motor? I would suggest cleaning the pistons ala grippy style and puttin that sucker back together. BTW, cool pup!

 

What is Grippy's style?
