ok the old f22a4(200k miles) has a problem where the alternator belt has rubbed against the timing belt cover and made a hole. i just ignored it since i was gonna replace the engine anyways. the new engine jdm f22a(30-40k miles from tiger) seems to have the same mark on the lower timing belt cover. also the crank pulley seems to have worn into the cover as well.

i have read many other people have this problem but have not seen a definite fix. is the crank pulley on too far? timing belt cover was not installed correctly?
plan to do a full timing belt service since it was obviously run with the whole in the cover

 

There is suppose to be a "seal or washer" behind the tension adjusting bolt-between the cover and the bolt-outside of the cover. Bet yours is gone.......with heat and time without this "seal" the cover will warp. Last time I did the tbelt on the 95 I put an e-clip on there instead of that rubber seal.

 

just ordered a new timing belt cover with seals. not sure of where this bolt is you are describing but ill go try and figure it out

 

You'll see it. Should be poking thru the cover, it is the one for adjusting/setting the tension on the timing belt.
