Who's to say whether it will or not, I don't think any psychics surf this board. I know people who have had a rock get wedged between the teeth of the oil pump gear causing the timing belt to slip and their valves to become real friendly with their pistons. I have the top cover off on one of my cars and I haven't had any problems for 2 years, but who knows what tomorrow will bring. Basically if you have the cover why not use it? I misplaced my upper cover and in my laziness never put it back on.

Re: what can happen if i run without the timing belt cover? (RedlinedVTEC)
its REALLY ugly on a sohc...
its like you have metal metal metal and then this ugly gray plastic thing...
im in the middle of a mini me so i'm gonna be changing the belt anyway, and if i dont have to put the cover back on id rather not
plus in the future if i get an adjustable cam gear i mean... they make em aonized blue for a reason right

yeah, i think there is a lot more danger by not running the bottom cover, but as sayd above, its all luck.
i have had my top cover off for like 2 yars and no problems yet

I have first hand experience. SOHC sucked a rock up off the freeway and snapped the belt at 80mph...in the middle of nowhere too.

Maybe, maybe not. Are you willing to take the chance? BTW, I think they look like crap with the cover missing.

Re: what can happen if i run without the timing belt cover?
It bothers me how many people run without their covers, especially lower covers on a b series, with no good reason. If you bought it that way or it broke, I'd understand, but it is usually laziness. This means as a guarantee, if the distributor has ever been touched, your ignition timing is almost completely guaranteed off (even by a little bit). If you ever want to buy someone's "performance B series" and there is no cover, they have not been servicing that engine correctly.
I care more so for the ignition timing. I will say regarding risk of rocks on an integra with factory AC and power steering ETC., the chance of a rock coming up is probably slim compared to any civic b swap (because people usually are not running an AC compressor, PS pump, AC lines, etc.) and there is a lot more room in a civic engine bay for rocks to jump up into the belt than any engine bay with all sorts of pumps/compressors able to deflect more.
The more open your engine bay, the higher chance something can jump up and kill it.
It Also really bothers me that they couldn't design a cover easier to put on like a external only two-piece, and that they kept changing the sizing between decks on the B series. The problem with tweakers starting to remove the covers probably partly stems from the valve cover eave/overhang, covering the top of the timing belt, giving people an extreme sense of overconfidence, simply because the cam gears are covered... The timing belt cover should only be dummy proof and not try to be water tight (referencing D series covers). Having to pull the valve cover off and the cam gears is ridiculous in the grand scheme. LS is different than GSR is different than B-16, etc. I will find out soon whether or not I can make a B18C set work, specifically the upper covers work for LS/VTEC Swap (which seems to have no solution and only one forum even vaguely addressing with no clear proof of a solution). But what really matters for engine safety and performance is that lower cover with ignition timing.
Will report back how a B18C cover works on LS VTEC setup (B18B1 block, B16 head, and I am even using a 1320 manual tensioner so mods will be required I will try to record that as well).

Re: what can happen if i run without the timing belt cover?
Yes, this goes to show the lack of support out there for the LSVtec concept regarding the timing belt cover. It's not like '90s car's advanced really, mods died off after 2015. And the community is definitely dying down a little bit.
