Latest status on the engine = problem:
 
Unfortunately a breakdown in one of = the=20 households most important appliances ( in the wife's view), i.e. - the = washing=20 machine precluded me getting the engine unbuttoned today.  Got as = far as=20 getting the flywheel nut off when got side tracked.
 
However, here are some interesting = tidbits. =20 Al told me he could not find an NGK B9EQV - odd I thought- = since I=20 purchased some.  Well when I opened up the tool box there as = plain as day=20 was B9EGV - the CORRECT PLUG - I am beginning to feel like I am in the = twilight zone.  All four -all are the B9EGV!
 
So the right plug - so how come the = problem or=20 was it all an figment of my troubled mind? 
 
No figment about the problem, I could = better=20 examine the apex seals through the exhaust with a bright light.  = I found=20 one apex seal shattered into three pieces, one stuck down as if = springs are=20 broken and one which appears to move normally in its slot, but has=20 nicks.  Well as we all know when two of the apex seals are gone = on a=20 rotor they might as well all three be gone.
 
Now here is where it gets a bit more = spooky - I=20 took one of the B9EGV plugs and screw them into an 86 NA rotor housing = (thanks=20 for the suggestion, George - down under) I have laying around.  I = then=20 measured from the inside of the housing to the ground electrode of the = plug -=20 hold onto your hats - it measured 7.5 mm!  I could be off by a mm = but=20 certainly places the electrode no where close to the chamber (relative = speaking).
