Default Timing belt guides

I just bought this 02 wrx wagon. As with all used cars I decided to replace the T-belt among other things ( seals, valve adjust, etc). I do have the FSM and noticed that my car does not have any of the T-belt guides. I can see where they bolt up, but they seem to be missing. I'm sure someone has been in there before doing a t-belt.

So my question is, is it crucial to have them? I see there are a few non oem places that sell an aluminum main guide.

Also I broke both rear covers behind the tbelt and cam gears, is this common? The bolts where so tight that instead of loosening they just turned the molded in nuts and would eventually bread out of the cover. I ordered both rear covers but have not yet ordered the guides.

ok, mine is a manual trans. Looks like there is one in each corner and then the main one above the crank gear.

Personally, I would put them on in a manual car. My belt had marks on it from contacting the guides when I took it out to replace it. In manuals, when you let off the gas abruptly, the belt slacks up and that's when it can jump. The guides are there for a reason.

It's tough to get them perfectly spaced. I took an old (long) hose clamp and cut the metal into two pieces. I put them in between the belt and the guide, pressed down, and tightened the bolts up. One thickness of the hose clamp was too thin. 2 was perfect. Without something in there, the guide can tilt to one side when you tighten the first bolt. It's just a nice easy way to quickly make sure they're spaced properly and evenly.

FWIW, I also did the belt on my girlfriend's WRX. Her belt did not have any contact marks. She drives like a normal person. I'd guess that the belt slacking up is a direct result of quick lifts from WOT, such as what I do to my car at autoX.

I read that the reason they are on the manual is it the engine could turn backward and the tensioner will not take up the slack when being pushed that direction.
