if a spark plug wire is fouled and the engine isnt running on all 8 cylinders could this be damaging to the crank or any other parts of the engine (ie due to a fuel flooded cylinder) not really sure about any of this... help anyone?

 

I doubt it. It wouldn't really flood the cylinder; just fuel air mixture flowing in and out of it.

 

i rode with one of my plugs disconected for about 10 miles...i could hear a ticking but nothing happened...so far...it's been about 100 miles later...

 

One concern would be that raw fuel collecting in the cylinder could tend to "wash down" the cylinder walls and promote wear. Most of the fuel will be blown out, but some could collect.

Also, raw fuel blowing into the catalytic converter can overheat and damage it.

Are you just trying to figure out if you've got damage from running a long time on 7 cylinders? Mostly it will depend on how long it ran like that. If no codes are being set and the engine is running OK, you're probably allright. But, if you want, you can run a compression test and see if that cylinder shows up low.

 

a friend of mine had his car running on a bad wire for about 500 miles... wondering if he has something to worry about and if so will he notice the problem or will it go unnoticed causing more problems

best thing would be to hear someone elses story

 

I had my #8 cyl not connected on accident once when I went to the dyno, I did spin a rod bearing on that dyno pull but it was #5 cylinder.

And it still put 320 down!
