Doing a bit of maintenance on my recently purchased NB8B
It had been serviced by Mazda dealers exclusively until I bought it.
It started when I fitted some front mudflaps.
Pulled away the rear part of the front innerguards, I found the guards packed with leaves and gunk.
Used an air compressor, I pushed some air through the drains from the front windscreen and in and around the guards.
Remove a pile of crap from both sides.
This got me thinking about the soft top drain holes
If you have never cleaned these before, I recommend you grab a vacuum cleaner before you start pump air down these holes.
Give them a good blow with the vacuum nozzle close by to catch any blowback.
Also recommend you do it before you clean your car as it can (did) make quite a mess.
There is an article on the Miata forum on finding and cleaning the soft top drain holes using a long brush if you don't have access to a air compressor. http://forum.miata.net/vb/showthread.ph ... ight=drain
If you use a brush, check the rubber check valve is correctly positioned once you have cleaned the drains.http://forum.miata.net/vb/showthread.php?t=178793
If you don't do it, Mazda wont.
