So what are your guesses?
I wondering if the oil rings are fubared on #8. A quick visual would confirm the spring ain't broken & did we check the seal? I was thinking we did. but if #8 blinks differently than the rest of em, plug wire or check the underside of the cap, the # 8 brass terminal. didn't we replace the plug wires?
Yep brand new plug wires, brand new plugs, brand new cap and rotor.
And number 8’s plug is never oil fouled it’s always fuel and it even smells like fuel.
I’m seriously thinking valve spring.
Something is letting more fuel into cylinder 8 which is causing the plug to semi fuel foul.
