About Josh Fields Expertise I can answer questions related to the BMW e30. These are the cars produced from 1984-1991 (1992 for convertable) in the United states. I am more fluent with the six cylinder models, although few things changed for the 4 cylinder cars. I know most of the problematic areas of these cars, and have found ways to fix them.
Experience I have owned six different E30's over the last 10 years. I do all my own work, and know about ever nut and bolt on these cars.
Question Recently had a thunderstorm. Found that the passenger side of my 325is ('90) was full of water. I know it's coming from the outside vent just below the windshield. What can I do?
Answer Albert,
If you are talking about the vent beside the wiper arm, then this is a common problem. It's obvious that water can get in this vent when it rains, so BMW designed a drain in this vent. Most of the time the leak is because of the drain getting clogged. Those vent covers just "pop" off, so you could take a water hose and spray out this vent to possibly dislodge the blockage. Sometimes when this drain gets blocked, water will sit in the cowl and finally rust away, leaving a hole(s). If you clear the blockage and are still getting leaks, you probably have a small rust hole that is letting the water run down that way. Try to locate the hole and close it. if it's a small hole you could use silicone or some other sealant for a good fix. If it's a large hole, you might have to replace some metal to fix it right.
Good Luck!
Josh
