Sorry,
EJ25, 1999 Legacy SUS AWD automatic.
I'd pull the motor again. The torque procedure for the heads and the timing belt/cam timing setup would be harder on the car.
Heck, I even changed the spark plugs!!
I don't know if a manual trans would complicate things much.
A note about the oil cooler:
I bought the flex-a-lite kit #3951 from Summit.
It's easy to do, but I had a persistant oil leak from the filter gasket area.
The sandwich adapter is machined for a built in "thermostat". The corners of this squared off machined area is located right at the gasket of the filter. When pressurized oil pushed past.
I tried a Fram first, forget it!! oil poured out! Then I used the old filter, a Valvoline VO61, it slowed down the flow, but still leaked.
Turns out the Fram gasket is even smaller than the Valvolline unit!
Well, I did some investigating, and ended up using a Dodge Colt filter thats bigger all around, but has a gasket that's about 1/4 inch larger.
No leaks, good pressure. Specs are similar except for a slightly higher bypass valve pressure.
