Re: 1931 Pickup Engine Knock
I don't see the backwards dipper. I see the threads on the bolt that may look like a backwards dipper.
There are all sorts of things that can cause a knock. They are listed in Les Andrews' Troubleshooting book (the blue one). It can range from a bent rod to loose bearings. Everything has to be measured and examined. It really needs the engine removed from the car and gone through in detail.
