Default 07 impreza- oil on spark plugs

I have a 2007 subaru impreza 2.5i with about 47k and while I was changing my spark plugs i noticed that they have oil on the top of them. The wire caps as well. Any ideas as to what is causing this? Maybe valve gaskets?

There's not really anywhere else it could be coming from.

I've had this same issue before at 80K.If you search on google for impreza valve cover gasket kit there are some websites which sell everything you need as a kit.The kits include the valve cover gaskets,the spark plug tube gaskets and grommets needed to be replaced while your in there.I inserted below a link you can take a look at.http://www.google.com/gbproducts/...ek+Google+Base

Definitely tube seals. My 04 had this too when I bought it at 44k miles.

How many miles do you have on you 07 2.5i? I'm just wondering when I should expect something like this on my 09.

My 06 2.5i had the same thing at 98k miles. At 108k I did the timing belt and water pump and replaced tube seals, valve cover gaskets and adjusted the valves while it was apart.

Seals are moderately easy, there are good write ups on here on how to do it.

BTW anyone who is less than 5yrs/60k miles should still be under warranty. Oil seals/gaskets fall under Subaru Powertrain Warranty. You should not have to pay for this repair.

I noticed this when i bought my car at 79k...I thought this was normal on these types of engines since it was my first subaru. Wow do i feel like an idiot.

oil was on the threads of the spark plugs

is this something I can do myself if I just buy the kit?

yep..I have an 07 2.5i as well that had the exact same issue. The dealership found it actually when I took it to have my 60k service done. Should have been covered, however I took it in at 61k and got fuc**d.
They did replace my cat. converter at 74k when it kicked the bucket. It was warrantied to 75k..LOL. Would have been a nice $700 to replace it if I hadn't of been pissed off about another thing going wrong with this car with such little mileage and bothered to ask if that was under warranty still.

I figured since the 60k warranty was up nothing would be covered, but it paid to ask.
They really need to up the warranty coverage like everyone else has. I drive 30k+ miles a year and that warranty is pathetic.

I found the same exhaust kit on Amazon for less.

Amazon.com: Fel-Pro Vs50561R1 Valve Cover Gasket Set: AutomotiveAmazon.com: Fel-Pro Vs50561R1 Valve Cover Gasket Set: Automotive

It's cheaper for me because I have amazon prime. Free 2 day shipping

I had this same problem on my 05rs, I think my post got skipped over. Just wanted to know if this gasket set is something I'm able to put on by myself before I order the set.

#1 You could have called Subaru or had the dealer call Subaru and request goodwill repair coverage, since you were only 1k out of warranty. Not a guarantee you would get it, but a very good possibility it would have been covered. SOA is pretty good about that.

#2 Subaru's standard warranty is reasonable and very comprehensive. The 100k warranties that some brands advertise cover very little and with alot of stipulations. If you really wanted more warranty coverage, Subaru offers it as an option, up to 7 years/100k miles. I got that on my Baja and it only added about $10 month to my payments over 5 years. Really a drop in the bucket. Other manufacturers do charge you as well, including the "standard 100k warranty" and just including it as part of the MSRP. Either way you're paying for it. With Subaru, you dont have to pay for it if you dont need it.

I would call it a mildly advanced procedure for a novice mechanic.
Some of the lower valve cover bolts on the '06 are a pain to get to and almost impossible to torque with a torque wrench.
The Valve covers are a little trickly to remove, you have to rotate them 90 to get them out.
Replacement is pretty straight forward just make sure the valve cover gasket remains seated during reassembly or you will pinch it and get an oil leak.

Take your time, follow the directions, have fun, and in a few beers it will be done.

Its your valve cover gaskets and seals like mentioned above. It is actually a really easy job to do yourself. I did it with a mechanic buddy of mine and took about an hour. make sure you have extra oil and check the seals before you go for a drive.

Is it necessary to drain the oil first? Need to do mine soon. Dripping onto my uppipe and smokes and smells. Figured if oil leaks out now, a lot more will come out with the cover off. Lol. Just want to make sure though.
