This is the first FB I’ve heard that’s had a dripping problem. Over the years I’ve done 3 of my EJs’ VC & spark plug tube seals but haven’t had any issues with the FA/FBs yet.
Not saying it won’t ever happen, because flukes happen, but now that I’ve switched over to a certain oil, I know that the seals & gaskets have their best shot possible at a long life!
Cam carriers and covers on both sides. Passenger side got to the point it was dripping pretty bad. One of the worst ones my dealer had seen. It definitely had plenty of undercoating on that side
My '99 Legacy GT Wagon with EJ DOHC engine unsurprisingly developed weeping cam carriers at about 10 years old/ 100k miles. Switching from regular Mobil 1 to the HM version mostly stopped problem; after that, consumed about 1 quart per 2000 miles. That car is still in service with a young relative.
Old joke: "If your Subaru isn't leaking any oil, it just means that there isn't any left in it."
I have a 2017 OB with the 2.5. When using Mobil 0w-20 it uses a quart about every 3500 miles, with Castrol Edge 0w-20 it uses a quart every 5500 or so. Doing 6K oil changes (miles) but will start doing 5K.
Guess I got lucky with my 2017 Outback with the 2.5and 62k on it. I have had mine for little over 2 years put a little over 40k on it. Burns or leaks no oil. Have been running Castrol 5w30 Edge or Edge ep in it for 3-4 k oci.
