I'm not sure what "low miles" is... but mine was in the 20Ks I think when I noticed it (might have been 30s, I'd have to look it up)...

I would say 20-30k is respectively low amount of miles. I don't know if the warped theory would work with such a minimal amount of miles, but I don't know enough about the subject to say anything. My baby is almost at 100k and it has olympic size pools in each one haha.

Sorry for my noobness on the subject, but what are some visible signs of leaking valve covers/o-rings?

I have never noticed oil consumption w/ my motor--levels are always b/w H and L between 3k Amsoil oil changes.

I do see some minor condensation on the top of the valve covers though. Revup engine with ~25k mikles, ~4k miles boosted.

other then obvious oil consumption and check engine light with mis-firing, its hard to tell unless you pull out all the coil-packs individually. if any of them are leaking you will see the oil at the tip of the coil-pack or shine a flash light down the tube. we usually discover this when we are performing spark plug changes on cars with anywhere from 70k to 100k. we would advise you that have someone take a look before your warranty runs out.....

^^thx for the input. I have an 05 so no more warranty. Only time my cel flashed for misfire, water likely got on filter/maf after a wash, but went away after time to dry. Just changed out plugs for a retune. Might take a closer look next plug change. But I don't have noticeable oil consumption or or obvious oil pools around valve covers. I do have an arc oil pan that adds an extra qrt of oil.

yes, you do have to remove valve cover to perform this repair...it is same as if you were to replace valve cover except with our o-ring kit you don't replace the whole valve cover. there are two ways to do this. either we just sell you the kit and you replace the o-rings out yourself or we sell you ready to install valve covers and you return your old valve cover to us.....detail on prices and procedure is posted on early section of this thread....if you have any questions please feel free to contact us...thank you

Pics of said o-rings? How is this possible? Do you just place the o-rings over the top of the OEM O-rings?

lol....what some people should know is that even when you change out your rings (which you should do if you do have a leak in the spark plug hole) is that the new ones are just going to go out as well (depending on the severity of the situation).

what happens is the positive crankcase ventilation system isn't working properly. So when there is an issue with the system then it sucks oil up from the VC into the intake manifold which then gets sucked into the combustion chamber to be ignited and blown out the exhaust. But when oil starts to accumulate at the top of the VC (on the inside at the top where the rings are) because of inproper PCV it will eventually eat away at the O-rings and causing a leak into the sparkplug hole, which then can also lead to misfire due to a damaged coilpack. High heat mixed with oil and rubber/plastic (O-rings and coilpacks) is a bad combination.

It could be bad PCV hoses (cracked, deteriorated, ect.) and/or it could be a blockage in the hoses. What you need to do when you do get new o-rings or VC is service your PCV hoses. Ensure they are in good condition, flush them of all excess oil, and check/clean the PCV valve. Or else the new O rings or VC or coilpacks are just going to go bad on you again in time. Fix it at the root of the problem first then work up.
