Bad cylinder

[FMF300EX]

Did a tune up on my woods truck Jimmy (new cap, rotor, wires, plugs) and noticed one cylinder is bad (unscrewed the plug and quite a bit of oil came out). I know this means the rings are blown or whatever in the cylinder, but are there any thing to atleast help it somewhat without tearing the engine apart.
I have seen a ton of emmissions and other liquids that are supposed to help seal up scorns in the cylinder, but would any of them help any for bad rings? Just wonder, I do not mind running on 7 cylinders because it is just a woods truck, but thought I should atleast check.

There's no real miracle additive that will fix something that serious to be honest. However since it is just a bush truck and it's not a big deal you can -try- running some "Engine Restore" through it every oil change (maybe double up the mix the first time? I don't know if that'll be bad or not). I ran it in my jeeps beatup 4cyl and it did wonders for it, I'm not a big "miracle in a can" guy but this stuff helped that old engine out. I did a quick review on it on my YJ forum, I don't know if I'm not supposed to link from other forums but here we go:

It's still something that needs a mechanical fix but if you don't want to do it you can try that stuff.

Thanks for the reply.

I am 16 and purchased this truck for 300$ with the intentions of a woods truck/ road truck when I get my license in September. I realized it would be best kept in the woods where it belongs, so I am not looking to do that extensive of work to fix the engine up for something I just beat around. Also, I would prefer to spend as little money as possible on it seeing how I need money for a truck on the road.

Anywho, about the Engine Restore stuff...

It seems to be worth a try, even if it sealed it up a little bit and cut back on smoke cloud some, it would be worth it.
Do you just pour this stuff in and that is it? It just had a recent oil change, so I do not want to drain good oil and spend money on more if I do not have to. So just pouring it into the existing amount of oil would be best.

Thanks again

No oil change necessary, just add it the same way you add oil. If you plan on pouring "lots" in make sure you drain out some oil to displace the amount you are pouring in. Adding 1 6cyl can to what oil is in there already will be fine, but if you add 2 or 3 cans (I don't even know if that's recommended) make sure to drain a bit of oil so it doesn't "overfill" the crankcase. I've always added 1 can to my jeeps engine each oil change in ADDITION to the oil already there. hth

Alright thanks man. I am going to try and pick up a can this week at PepBoys, but I do not get down to where my truck is until the weekend so I will try to get results after running it with Engine Restore. Thanks again

It might not be your piston rings that are bad. It could be the valve's o-ring seals in the cylinder head that are letting oil into the cylinder. In that case, some of those "miracle in a can" solutions may work out better than you think.

Yea Engine Restore is great, I even used the fuel additive but for some reason cant find it locally. Dump some in and let us know...
