OK...I must fess-up.
When I was a stuggling college student I had a 911 that had this anoying oil leak. Being a bit mechanically challenged and poor I came-up with a $5 solution that worked.
Sorry no pics, but...
I took a small flask about 6" long and 1" thick and installed a flip valve instead of the screw cap. I then put a dent on one of the flat sides with a hole in the middle. The flash was then mounted in under the car in just the right spot...
Because my oil leak was real consistent where it dripped, the flash would collect the oil drippings and about once a month I just opened the valve and drained the flask. Worked pretty darn good-my 911 no longer left little
wherever I went. The flask was my little secret, and if someone did look under the car it looked like some type of performance gadget bolt-on...too funny. Now I'm an older fart, and I don't care what other people think.
