Oil for GM 3.6l famous for timing chains.

It's what makes a Subaru a Subaru.

But actually -- it needed a rear main seal and valve cover gaskets. Doing valve cover gaskets on one of these cars with the engine in the car is a fools errand when the engine is so easy to pull.

I wonder if all that PYB super cleaning ate through your gaskets.

No idea but I've never personally seen heads that clean that weren't fresh out of a parts washer/hot tank or brand new.

As long as it doesn't eat through the RTV or whatever gasket is on the timing cover! I have nightmares about all the little tiny bolts that hold it on and how many I would end up breaking off.

Why is a 96k mile engine out of the vehicle?

To change the spark plugs!
