1991 Acura NSX: Make It Rain

November 14, 2011

So, remember when I said I was "given" the NSX for the weekend? Well, here's the reason.

As it was supposed to rain quite a bit here this weekend (it didn't, natch) I was given the task of driving the NSX around in the rain and then inspecting the hopefully wet trunk to come up with a possible source of the leak.

On Saturday, armed with my smart phone and an ever refreshing Doppler radar image, I did my best to hunt down rain. As I didn't want to smell like Magrath did after all his clothes got soaked and then baked in the heat of the trunk, seriously, the man smelled like mulch, I decided to leave the trunk empty and go into full storm hunter mode.

As luck would have it, all I had to show for 200 miles of Doppler guided driving was a smeared windshield and frayed nerves. I'd be surprised if I encountered more than 5 minutes of light rain. Click on through to see what came next.

On Sunday, I turned the hose on the back of the car and let it rip.

Before you get all bothered with the idea of me blasting away at some unsuspecting rubber seals, know that every new car goes through far worse leak testing before it makes it out of the prototype phase - Corvettes and F-Bodies excepted. Those cars should have come with a complimentary poncho.

Anyway, after tracing the seals around the trunk for a few minutes, I popped open the hatch and saw that, low and behold, it was leaking just above the tail lights on both the left and right side. To be fair, it wasn't much, but, to be fair, it shouldn't leak at all. You can see the compromised seal and the water droplets in the picture, below.

As I noticed the trunk's reluctance to close easily on Friday, I figured that the bumpers might be out of adjustment. Sure enough, the right side was cranked down significantly farther than the left one, so I adjusted the left one to match the right, shut the trunk (it shut perfectly) and did the test again.

Unfortunately, the trunk still leaked on both sides. As reader huyracing (who seems to own an NSX) suggested, we might need to replace the tail light seal. Will this keep me from driving the car again? Not a chance. This car is cool.

Stay tuned for the fix.
