On my 89 5.0, I have BBK Headers and the dipstick is all bent, just barely can get it out. This one doesn't seem to be reading any oil, and my friend said I would need a Ford Racing Dipstick, which is like 20 bucks or more. Is this true, or would a regular dipstick be fine?
A Ford Racing dipstick is bent just like the factory one. In fact all it is is a factory one that has been chromed. I can't see why yours would be so distorted either, most if not all aftermarket headers allow plenty of clearance for the tube. Worst case, try a used one from a yard before you buy new if thats your preference. This way you know it works and that somebody screwed this one up.
