Strange engine noise I've go a 1998 TI. Anyone had any experience with this problem? In the winter, say below 35 degrees, when I start my car, I hear a 'slapping' or 'clicking' sound - seems like it comes from just under the valve cover in the front of the engine. After it warms up, the sound goes away. Then, during the summer, it starts again whenever I turn the A/C on. And it keeps clicking until I turn the A/C off. I just replaced the secondary air pump - it seems it started around the same time. I also replaced the secondary air check-valve. This clicking sound sound like it is right behind the air check-valve under the valve cover. |
