Valve Cover Gasket replacement Subaru WRX:
This is a step by step guide on replacing the valve cover gasket on Subaru flat four engines. This guide will work for most Subaru turbo cars 02-07+ and most other naturally aspirated Subaru cars.
1.) Jack your car up and drain the oil. Remember to put the car on jack stands. You don’t want the car dropping on you.A lot of people do this job with the oil still in the pan, but its better to rather play it safe and drain the oil completely.
2.) Remove the front air scoop. It takes two 10mm bolts.
3.) Remove the nice Cold Air intake box.
4.) After removing all that, you should see this a total of 8 outer bolts and the 2 inner which holds the spark plug coils.
5.) Unscrew them and label them. You don’t want the bolts going into the wrong place. It was a very hard to get any decent clearance so take your time.
