Looking at a 73 cruiser project trail rig. Owner says that the engine lost power and appears to have little to no compression. Mileage on the truck is around 90,000. Is there anything I can to do get the compression up short of a rebuild. Does anyone know any tricks? Engine restore? 90Wt gear oil in motor? How bad is it to replace the piston rings on this motor.
thanks
