Plugs covered in oil. HELP!!!!
 

Decided to try pulling my plugs to see how they were and....we'll....pictures speak for themselves. First pic is drivers side, 2nd is pass. Dealership, here I come..... with mods.....and 52,000 miles......balls......

Looks like this should be covered under the 100,000k lp warranty. Catch can, flows axel back, and injen. Those shouldn't be related.....right?

WOW! perhaps this is where all the oil is going that is mysteriously disappearing!

Holy cow. That's bizarre. Maybe you're right, Screamin.

the oil appears to be on the outside of the plugs, maybe leaky valve covers. shouldn't be a biggie. :)

Could explain the vacuum leak I've been chasing......

Awesome catch there!

im scared to find out how mine are going to look tomorrow.

Op, did you experience any problems or bad idle that made you want to check your plugs?

Yes. Been hunting the cause of hesitation under light throttle and rough idle for a while. I suspected vacuum leak but couldn't find it. Looks like I finally did. Plugs are healthy - or as good as a 52-53k old plug can. They look a little lean on the pass (oily) side, but drivers are perfect. Really looks to be a valve cover gasket or something like that, not the top end motor rebuild I thought when I first pulled it.

No cel, no sign other than rough idle and throttle hesitation. If you're having this problem, pull your plugs. But pull atleast one from both sides - I pulled a drivers side plug a few months ago because they're less of a 'pain' to get to. Pull both.

Are you routing your Rx catch can line over that area?

Looks like the oil is falling in on top and pooling around that left side plug.

Perhaps you've got your vacuum leak somewhere in that line (hard plastic is cracked?) and its tracking down something and ending up in the sparkplugs hole(s). :iono:

No. No oil outside the motor and my line from the crank to the rx runs in that area, but not that close. It's internal. Spark plug seal/valve cover gasket is my guess. Makes sense. Plugs are in between the cams in the valve cover. Bad seal = hello oil and hello vacuum leak issue ive been having

Pretty sure I just got an epic 4 hour run-around.

Took it to my dealer. They said they couldn't find anything. However, despite me telling them I suspect a vacuum leak and showing them the picture above, they didn't check anything to do with the valve cover or the plug wells. They hooked it up to the computer, no codes..... told them that. Reset ECU.... did that saturday. They said "oil in the spark wells isnot uncommon for an engine with that many miles"....huh?? 53,000 miles? They didn't even pull that plug! My engine bay is fairly dirty thanks to not running the engine cover and a lot of construction on my drive, and I see no sign they touched that side of the motor.

Saturday I'm going to pull all 3 from that bank and figure out if they all have oil. If it's just one, bad spark seal. That shoudn't be too hard to fix.

well, at least you have it documented in case it becomes an issue in the future.

Damn right. :headbang: Saving the service order and the computer results they gave me.
