When I was not using the car for a while I removed the battery and charged it before storing it in a warm room. Batteries do self discharge. That what a battery maintainer is for. The maintainer continuously replaces what the battery self discharges. There use to be a myth that the electricity esca...

The Volvo white block Oil pump is a Gerotor pump. I don't think there is any way to change the geometry and make a higher volume pump that will fit in the space provided. There is rumor that the RNC Oil pump is bigger. You might look into building a RNC block and install it instead of the RN block. ...
