I have a 1995 civic hatch vx. It's a d15z1 motor with vtec-e. while driving when motor is hot or cold it makes a scraping noise through acceleration at 1500rpm and stops at 2000 rpm. If you smash on the gas or are climing a hill the noise will proceed to a higher rpm. It doesn't feel like the car is effected by the noise. It started about a year ago and as got worse. If someone knows the issue please help its my daily driver. Thanks
