And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Geeez…. Must be from a mid 80s engine when all that smog control shit was recycling exhaust gases back thru the engine…and made the whole engine dirty…inside and out…
Well they are ngk. On the outboard drag engine we go through a bunch, they start leaking at the packing washer at the insulator. Champion ain't no better tho.
The pointy center electrode means they are most likely late model iridium plugs meant to last 100,000 miles for emission reasons. The oilyness is most likely fouled oil control rings from infrequent oil changes or the cylinder cutoff system to conserve fuel. The pistons will cool off when they are deactivated and to keep them up to temperature hot oil is squirted up into the underside. This will coke up the oil control rings so they do not "oil control" but let oil pass to the two compression rings, coking them up. This allows excess oil to enter the combustion chamber and be burned off initially but as the mile add up, the burning off is reduced and voila, fouled plugs.
This is why I am keeping my '16 F150 instead of replacing it. FOMOCO's coyote motor is now doing this deactivation crap. Don't buy one.
I think NGK uses 'PZ' to indicate Platinum tips, I have them in my V8s. The engine they were removed from is running too rich and probably needs the O2 sensors replaced. Al_in_Ottawa
Well used piston rings too, it appears.

ReplyDeleteCan still be used for sinkers.

You see? Women wonder what we are thinking about, this is what we think about.
