Anyone heard of this?

I have a 97 CVPI with 92,000 miles. I put on a 70mm throttle body a one inch spacer, a ported ADTR plenum and an intake. I've had the intake on it for about 20000 miles and recently the motor started making noises so i had someone come get it and take it apart. he told me a piston was slapping the wall of the motor, and the reason was because the car was gettin too much air and gas because of the intake. I think it is BS because it never made noises until recently b/c i didn't change the oil for like 10,000 miles or so. Anyone heard of too much air causing this type of problem?

does your vic burn oil because if it does neglect from checking the oil could have let it eat up to much oil and allowing a cilinder to not get enough oil thus major damage occurs
