So since I had some spare time on my hands, I decided to tackle the PCV valve, new Cobb heatshield, clean MAF and replace the cabin air filter......
All I have to say when it comes to that PCV valve to Subaru is
.....it's not very servicable on the 07s. Tried heat and all with 2 of us, no go, just cleaned and re-installed.
Forgot that some of the brakets for the heatshield are in my storage unit.....so no go today
And that irritated me enough to not bother with the cabin air filter.
Did clean the MAF though
Another day another try
