Default EJ22 related, couple questions

Alright, I have a 1996 Impreza L MT EJ22. I have a couple general questions, hopefully this is the proper forum for this.
  1. Would you guys recommend a block heater (coolant) from anywhere other than the dealership?
  2. Anybody have the back timing belt cover crack when replacing the timing belt cover? You epoxy it back together or get a new one? Mine cracked a couple of the ears off cause the screw was stuck in the molded retaining nut. I was thinking of just epoxing the whole thing back together... but just curious.
  3. What kinds of MPGs are you guys averaging with a relatively stock setup? I got 25mpg however, I commited to driving casually for this tank to see what kinds of improvements I could experience.
Thanks in advance.

I've had both the 95 phase 1 EJ22 and the 98 phase 2 EJ22..

1. Can't recommend anything. Is it really necessary? What temps do you see? I've never had a problem in some -10 degree temps.
2. If it breaks, it's fine, just get it together as good as possible. The dealership will charge and arm and leg for a simple plastic cover. Or get one off a junker if possible. Either way, you don't really need it. It just helps keep dust, road grime, and all that away from those components.
3. I'd get anywhere from 19-20 pure city driving up 30 MPG highway once. Usually I was around 26-28 highway though. All depends on driving habits, hills, etc. I did notice a 1-2 MPG jump with 89 octane fuel though... and it helped calm the pinging noises. I'd suggest it.

These are great engines which I never had one problem with running them for years. Just changed the oil.

The rear timing covers have threads that fasten the front covers to the rear covers with bolts. I don't think I have ever taken the rear timing covers off any Subaru without having them snap or break. I'd replace them if I were you.

My mother's 2.2 1995 Legacy Wagon AT gets up to 30 MPG on the highway, which I was pretty impressed with. That is running on 87 octane, but as cmiovino has stated, running 89 octane got rid of the pinging. My mother's wagon pings under load, time for 89!

Other than that these engines are great. Keep up with regular maintenance and it will never let you down.

Covers???....fix as best you can and keep going. Find a set of used if you can though.

Mileage, my wifes 99 Impreza L wagon 5MT gets mid 20's most of the time with low 30's when doing a lot of highway driving.
Currently it gets nothing, my son ran it too low on oil too many times. Sigh. It now has a rod knock and I'm looking at options.
