ONE CYLINDER NOT FIRING!!

K i have a 4 banger dodge shadow no turbo....and i was driving on the highway....and all of a sudden i started to lose power. So i thought i may have blown a plug. I did a tune up and noticed that one plug was real oily. SO i put in a new plug and started the car.... same thing...sounds like im running off 3 cylinders. So i disconnected the wire for that cylinder and started the car ..no differance..so now i know where the problem lies...but i have not figured out the what it is exactly....does anyone know what it might be?? valve problem maybe?? Any suggestions would be greatly appreciated!!
THanks.......

Sounds like a flooded cylinder if the plug was really oily. Are there any external oil leaks around the block/head area? Maybe a piston ring/seal is shot, causing oil to flow in.

Ignore bank he's been drinking and is looking for a fight.

why are u even here if it bothers you?? Go beat off to some japanese bukake vids or somthing

NO exterioe leaks. Yea im thinking an oil ring might be shot... is that possible at 95,000 kms....very low to blow a ring! thanks foir the feedback phenom

Most likely leaking oil around vavle seal! They rot and dry out, doese it puff blue smoke when u first srart it in the mornig?

ANYONE A MECHANIC??

Try replacing the Wires! Might had one burn out

Do you have spark to the cylinder?

No, this deffinately sounds like a seal, although with no external leakage, that leaves a huge question mark that can only be answered by an inspection. Either you drop it and start inspecting, or take it somewhere. You may even want to call and ask a factory that remanufactures engines. Alot of the places will have a customer service department, or someone that is extremely knowledgable and can either narrow doown the cause precisely, or give you a few things to try on your own. Either way by doing this, it will decrease your cost, or the chance of getting screwed at a local auto repair place. Hope something here helped.

do a leak down test and run a compression test...it could be a bad valve...it happened to my ford ranger, when i ran a compression test it would not hold in the number 2 cylinder, so i pulled the head off and i found i had burnt a hole in the exhaust valve...

YEs i am getting spark....and no blue smoke....i think it might be a valve seal gone....well its gettin inspected tomorrow...thanks for the input guys..appreciate it...any one have an idea of cost?? to repair a valve seal?? not doing it myself!!

really oily? definitely some oil getting into your cylinder...prey its not a valve seal ($$$$$$$$$), do a compression test and tell us whats up

i am a mechanic in my real life....the leakdown test is probably what needs to be done....but any competent mechanic with experience on these cars might already have a good idea what is wrong...
