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