난이도 & 준비물

난이도 보통⏱ 예상 60~120분🔧 리프트🔧 특수공구

증상

저속(RPM 2000 이하)에서 연석이나 콘크리트 벽 근처를 주행할 때 소음 발생. 엔진룸을 열고 유휴 상태에서 음원을 특정하려 해도 다른 엔진음 때문에 정확한 위치 파악 불가. 배기 매니폴드 가스켓 누유로 의심.

처리 내용

브레이크가 로터에 마찰되거나 휠 회전과 관련된 문제일 가능성이 높음. 이 이론을 확인하려면 차를 잭으로 들어올린 후 휠을 회전시켜 동일한 소음이 발생하는지 확인하면 됨. 같은 소음이 나면 배기계통이 아닌 휠/브레이크 관련 문제로 진단 가능.

An Aston dealer would have replaced the light and the gasket for £1million but he said a small dab of sealant would probably do the job just as well. He found a bunch of the heat shields around the exhaust were rattling and falling off so he re

Wouldn t feel too secure parking in a city.Good photos of the scenery - 911 going through a puddle! I had look back at the photos to see what you meant, I’d seen the pic but not noticed the puddle, I was far to interested in the Morgan peeping around behind the 911. A lovely looking thing, it would be my choice and I’ve always been a 911 fan.

TV8 said: The car has been locked in the garage for a few weeks as I recovered from some surgery and having to much time on my hands resulted in me buying a new exhaust system. It was fitted this week and overall sounds good but something isn't quite right and reading up tonight, hopefully, some adjustments will improve the situation!It certainly looks good!These "bypass" pipes (assuming they're not Helmholtz resonators) look like a Gundo hack type arrangement to increase noise levels.The whole system looks somewhat poorly conceived, overly complex in its Mk2 guise, and poorly executed, to th
