If the magnesium wheels thread isn't enough entertainment...
I finally got rid of the gas smell from my MkIV. Simply remove the gas tank and clean.
At one time the connection at the bottom of the tank leaked. It was put back with a different (I assume) washer and a liberal amount of black silicon.
When I removed the rear bulk head there was old, sticky gas along the front bottom of the tank. I hope its remnants from the previous 'leak' and not a coninuous leak.
Tomorrow, I'm raising the tank off the ground, plugging the holes and filling it with water and using a fill tube about a yard in the air. This water column should about triple the pressure seen by the tank (which is nominal), and check the welds (nice aluminum tank and welds, to boot). I'm keeping my fingers crossed for no leaks.
Then I'll empty the water (and the remaining debris) from the tank and swish with acetone.
Any advice???
