my h22 wont go in reverse

i have a 91 accord with an h22 and recently the mount bracket on the transmission broke and the whole engine tilted. i fixed that and everything was cool. around the same time, i would grind in either 3rd or 5th gear when i was in high rpm. i put oil in the tranny and got somewhat better. then one time after abusing the engine a bit, thats when i noticed i was having difficulty putting the gear in reverse. if i tried forcing it in, it would just grind so i gave it a rest. the next day i was pissed and forced that crap in. it went in but had trouble taking it out of the gear. later that problem seemed to go away. well, yesterday (nov. 6) i took the car for a spin in the freeway and when i got back that thing would not go in reverse. before it would at least grind if i tried to put it in reverse, now im getting nothing. it feels like im trying to put in gear without stepping on the clutch pedal. every other gear is perfect. i was either thinking the linkage got damaged somehow when the engine tilted, which i doubt, or its a problem in the transmission. anyway, its a bitch pushig the car when im parked so ill appreciate any help info or advice you guys have to offer. thanks in advance.

hows your clutch?

check syncros. I doubt it'd be clutch, linkage, or the motor being tilted; because you said every other gear is fine. Take it apart and have a look. You should never abuse it or force it into gear. If it doesn't go in reverse you should let the car roll back an inch or less and then it should go in gear, this is a commone problem with hondas.
