i have a 88 crx w/ a b16a swap and the car runs great, but when i shift into forth gear it grinds everytime. i know i have the clutch down all the way. the only time it doesn't grind into forth is if i shift really slowly, way slow. is my clutch going bad? i never replaced the clutch when i put the new motor in, but there is only about 1,000 miles on the motor since i have had it. i purchased the motor from hmotorsonline.com and they average 30-35 thousand i think. what could be the problem?
