Welcome aboard. Reference your leaky situation, go on my page. Look at the thread i created a few months ago, i think back in September of last year. My 97 had the same issue, you have to remove your hood. Its the vent where the fresh air comes into your car. I like your exhaust. You & i have the same 97's. I bought all new trim & painted to match. Kept my originals in the event i want to sell the car i will just take everything off & go back to chrome. Enjoy your car i& welcome to the forum.
Note: Please, please get rid of the decals on the side of your car. I love decals but you gotta try to keep it tasteful man. It has to match the luxury & the sport that goes hand in hand with these cars. Those decals simply don't go with the car. Sorry for the bashing but bashing is normal on forums.
