I had a front oil leak on my 235 when I first bought the '48 years ago. I was not ready to fix it right so I wired a cookie sheet (the one with 1/2 -inch side) under it. I can't find a picture.
Oil would collect and later during rain it would wash out while driving. Don't tell the EPA but I think the statue of limitations is over.
