Come to think of it, the glow plug light didn't come on once, which if I recall correctly is often due to 2+ failing glow plugs.

Might as well replace the fuel filters too. Motor mounts look ok (though one is kinda caked in oil), haven't checked the tranny mount yet.

Not sure of the last valve job. Bought the car roughly 3k miles ago. On my to-do list.

I'll audit the fuel lines too. Miiiight have a slight fuel leak... Car can be a bit smelly at times, and I get about 24mpg, but I attribute that to unknown fuel filter state, unknown valve state, etc.

Thanks for the replies.
