Pumpkin Cover leak

The cover will straighten, the cast will very likely crack if you try to straighten. Its probably already got a hairline crack in it which is where the oil is coming from. Spray it down real good with carb cleaner or laquer thinner until it is dry. Then watch and see where it wets at. If the housing is cracked you can grind a V notch in with a grinder then fill with JB weld.
I agree on the price, I sold an 8 1/4 about a year or so ago for $150. It was 3.55 suregrip.
