Vehicle: 1996 Legacy L wagon EJ22 (soon to be Frankenmotor)
2nd owner, just passed 200k miles (mostly highway grandma-style driving. Never overheated.)
Very regular oil/filter changes; Mobile full synthetic 0w-30
The motor has developed a lifter tick. It is sporadic yet consistently there. Mostly does it while at opperating temp. So since I'll have the motor out to service the valves, I figured I'd drop in a 1996 2.5l block that has 171k on it.
My main topic of interest/question.. I ordered the ej25/22 hybrid cometic gasket yesterday (100mm x .040" I hope that's correct...Those are the specs I've read everywhere for this application). This is before I've serviced the heads. I plan on resurfacing the heads via the shop bench-glass-sand paper-wd40 method. Did I just waste +$100 buying the gaskets first? Will I need thicker gaskets because of the loss of material during the resurfacing? I thought I'd be fine because 1.) motor has never overheated, 2.) this is the first time the heads will have been removed, ever.
Let me know so I can either relax or sell these and order a new pair...
