Ej253 Valve cover gasket replacement
Alright, i'm a complete noob when it comes to boxer engines.
That being said, i'm working on replacing the valve cover gaskets on a 2007 Subaru Impreza 2.5i with the EJ253 Engine. (NOT A TURBO) Questions: 1. Is there a walkthrough on here specific for this engine? (yeah,i have the damn rs25 walkthrough, but its not the same) 2. How do i attack the engine? Top, or bottom? 3. If i take the engine off its motor mounts, how much lift can be applied before structural problems arise (crap starts to break) 4. how do i work around the fact i have less than 1 inch between the valve covers and the wheel wells? 5. What tools are advised to make my life suck less when doing this? I have a full garage (vehicle lifts, jacks, engine crane, air/electric/hand tools, ect) Anyway i just need some help figuring out how to get to this thing without messing it up horribly. The engine layout has really made me hate this car.

Are you sure you have to take the engine out? I didn't have to on my 03 legacy... take out spark plugs, remove bolts (6 per side) holding on the valve cover, pull off, replace gaskets (3 - 2 circular and 1 long thin each side) make sure you have the spark plug gasket as well (2 per side). put everything back on. You will probably have to take of the air intake on the passenger side. batter and washer fluid on the driver side. I was able to do mine with it sitting on the ground and ll from above. Good luck

I've gone at it twice now, and i've been defeated both times.
First time, i didnt realize how useful a 10mm gear wrench was, so i bought one second time, I couldnt get access to the bottom 3 bolts, even with the engine off its mounts and lifted ~2 inches This third time, i'm planning on tearing the whole damn exhaust piping off underneath to get to the bottom 3 bolts on the valve cover. Whoever at subaru thought this was a good idea deserves to be punched in the dick. |

I think if you look up spark plug tube seal replacements you might have more hits since they seem to have more problems failing them valve cover gaskets.
Also have you tried a joint socket adapter? I used this on my 07 and it seemed to work fine for me, I've also used a swiveling ratchet wrench for them Last edited by alt14; 10-27-2012 at 11:23 PM. |

Aww man that sucks. My '03 EJ251 has enough space between the covers and the wheel wells. Even if you could get all the bolts out, you might still need to lift the engine to lift the valve cover past the spark plug tubes. GOOD LUCK!

Yours should be easier, it was the 06+(not sure about the new body style) that you had to lift the engine slightly to get to covers off

I manage to get them replaced on my 06 2.5i without loosening the motor mounts. I had the front of the car up on jack stands and tackled some of the lower bolts from the bottom I think I did need to remove the oil filler neck and also moved the fuel rail out of the way on the drivers side

Someone has posted a very in depth write-up with lots of pics. I thought I had it sub'd for when I change mine but apparently I did not. Search enough and you will find the thread.
