Default Oil around TOP of plugs

Hey guys i have an 07 impreza 2.5i. I have 61k and i just did all the maintenance. There was one problem i ran into tho. When i was changing my plugs and wires i saw that on the right side #2 and 4 had oil right near the top, by the valve cover, but not really of the plug itself. I looked around and i see that it could be the tube seals in the spark plug tubes. But the car is burning a little oil maybe a qt every oil change and wonder if it could be a bigger issue. I already had the valve seal replaced when i got the car at 45k. It was still under warranty so subby did it for free. But wouldnt they see this when they did that job, or could they have ****ed something up? Thankd for the help, i have pictures but i dont know how to post them

The valvecover gaskets and the spark plug tube gaskets just like to leak on the SOHC engines. Replace them and you should be good to go.

I have had mine done twice; once under warranty. They started leaking again after the warranty was up, but my dealership replaced them a second time for free because i had them done already. They called it a "good-will" repair, or something like that. Might want to check with your dealer they may do the same thing for you. I also have a 07 2.5i with 82k, mine where place around 65k

Is replacing the tubes hard to do yourself? You have to pull the engine, right? Do they normally change the tubes when they change the valve cover gasket? I just hit 63k do you think they will still replace them under the 60k warranty? Should I just ask them to do it under the good will warranty or what do I ask them. Thanks guys and hope I can get this fixed. Also is this why I'm loosing oil or would that not contribute to it?

On the cars up to 05, doing the valvecover gaskets and the spark plug tube gaskets yourself is pretty easy. On the 06 and newer cars, it's pretty damned hard. You're 99% likely to have to pull the engine. A few people have wrestled the engine around in the engine bay and gotten it to move enough to allow them to do the work but honestly they worked so hard at it that I think they'd have had an easier time by just pulling the engine.

So i took my car to subaru today and they said it was my right head gasket. The gasket i had replaced before was my left head gasket. So because i am 2000 miles past my 60k warranty they cleaned the oil off and said that i have to wait a week and come back to make sure that is the problem. They said that they will sign off on it if that is what it is. My only issue is should i see if i can pay for having the tube seals by the spark plugs while they have the engine apart just in case those fail and i have to take it apart again. Or should i just leave it and risk it? Thanks for all the help guys!

They only changed out one head gasket before? Yikes.

valve covers are pretty easy on SOHC just get yourself some ratcheting crescent wrenches. when you go to torque the bolts back on thighten them till they bottom out then give them an extra 1/4 turn

Ya they only replaces the left one last time and now the right is bad. I dont think they will just do the tube seals if they didnt before... Dealerships are ****, and i think they just do the minimum and nothing extra. Do they usually do just one or all of them when you pay for the job?

Don't be stupid. Dealerships don't do just the minimum, they do what they will get paid to do. Under warranty SOA only pays for the head gasket that is leaking. Your dealer could have lied to SOA and said both were leaking and done both sides, ethics be damned.

If you were given the opportunity to pay $1000 to fix the one head gasket that was leaking, or $2000 to fix one and replace the non-leaking one, what would you have done? Many people say they'd do both, but when it comes down to pulling out their wallet and actually handing over a lot of money to replace something that isn't bad (yet) they have a hard time actually writing the check.


When they do the head gasket, they'll also replace the valve cover gaskets and the spark plug tube seals, as they have to remove the valve covers to do the head gasket.


SOHC cars are stupid easy to do in the car, and pulling the engine is just an added line item on the invoice.

The kitty cat up there above me works at a dealership and ends up on a the wrong side of a lot of these arguments. There's a bunch of us that constantly try to remind him that the rest of the world doesn't work like the festering boil that is a dealership service department.

I have never once had someone decline to pay for both HGs at once. Without fail, they always want the second one done just so they don't have to deal with it again in 6 months. No one ever seems to have a problem writing the check to cover both. I suppose having people trust you not to rip them off helps.

I, along with a lot of other people, also don't feel the job can be done to an acceptable quality standard with the engine in the car. Sure, you can do it with the engine still in the car, but you're doing a half-assed job if you leave it it. Some people are ok with doing half-assed work. I'm not. If someone's paying me to do the work, I have an ethical obligation to do the best possible job.

He's also wrong about the HG replacement reliably leading to dealerships replacing the valvecover gasket, spark plug tube gaskets, and valvecover grommets. From time to time, I get to clean up the local dealership's messes when they neglect to replace those sales and then, to no one's surprise, they leak because they're age-hardened and don't re-seal when everything is put back together.

There should be no need to replace the tubes, but the orings that wrap the tubes and the gaskets can leak, causing oil to "pool" around where the plugs are

Default Leaking valve cover gaskets...

I found oil around the top of one of my spark plug tubes and I think I need to replace my valve cover gaskets. No one seams to recommend using the OEM replacement head gaskets for our engines, what gasket do people recommend using for the valve cover gasket?

Use the dealership valve cover gaskets... but I see you have an 07 like mine which as Ty mentioned (along with the 06) is different because of the AVLS and the resultant change in the valvetrain design... the trick to doing it yourself with the engine in the car is to unbolt the engine mounts and jack the engine up (and to the side slightly, if you put the jack sideways you can 'bump' it when you need the clearance). The passenger side you can get off without doing this but getting it back in with the valve cover seal staying in place is a royal pain, it's still challenging with it jacked up but doable. The drivers side is fairly straight forward with it jacked up and I had no issue. One trick I did find was using the 3M weatherstrip and gasket adhesive (this stuff: http://solutions.3m.com/wps/portal/3...beQH8HT14PGTgl ) in the valve cover to ensure it stays in place during assembly. I picked some up after the frustration of getting it all back together and finding out the passenger side had become misaligned during reasembly and was leaking. This stuffs super tacky, I suggest using a small flat head screw driver to 'paint' it in the groove so it only holds the back of the gasket.

While I agree with Ty that it would be easier to do out of the car, for those of us working in home garages without his experience where he can pull engines in his sleep this is doable and for me would have been much easier had I not been forced to do it outside in the winter during a particularly bad cold snap where I couldn't work for 15 minutes WITH gloves on before I had to go inside and get warmed up...
