I’m watching all this back and forth with many excellent fine
points, but first… there was mechanical interference that caused 2 of the plug
gaps to close way back when! I forget, how radical is the cam? Rick Haynes Dutkiewicz. From:

note: if you´re running a ballast resistor with your petronix, check that too.
It might be that your coil has worked well with the petronix because of the
ballast resistor. If that is bad this will cause problems over time. Also
check petronix page for trouble shooting. Von:

Hello
Richard, just
a few cents from across the atlantic. Before
getting into a lot of wild guessing, it would probably best to check if the
spark plugs are bent again. To be honest it would be pretty irritating that the
piston would hit a spark plug, but wont hit a valve. There
is possibly something in your cylinder 3+5 which causes the bent plugs tips.. It
might also cause the (exhaust) valve to stick or not close properly which than
would explain the fumes near the intake. As
it appeas to two cylinders my guessing would be parts of the intake manifold
gasket. When changing the spark plugs and they are bent again use a bore scope
to see if there is something in the cylinder, or if the piston top has damage. If
the spark plugs are not bent, check for your petronix. In general i´m happy
with them, but they can go bad too. Had problems with one after two years of
flwless driving. Found out I was running a coil with wrong ohm resistance,
killed the electronics. But it took a few thousand miles. As
said make an effort to check a few things and isolate the problem – than we
might all get closer to the problem. Good
luck Lars PS:
if you dont hear any knocks your rod bearings should be ok. If the compression
is ok, the likelyhood of having a broken piston ring in your cylinder is very
small. Also chances would even be reduced as it apears in two cylinders at same
time. Von:
