I had warranty issues with a few WAR engines. Pull them out and send them back to be checked. Get them back stating no problems found but still knocking on a rod or main or burning oil. That is when I pulled them apart and found cranks ground 0.005" to 0.008" undersize. So the clearances were way too much. The Ford dealer had found the same problem and we decided not to use WAR rebuilt any more.
Had problems with the engine machine shop in Yorkton also, so ended up taking dismantled engines to either Saskatoon or Regina to get machined. The Ford dealer could do valves and guides.
I do agree there are many wannabe mechanics with just enough knowledge to be dangerous. Like brake shoe leading and trailing shoes installed in the wrong positions or both leading on one side and trailing on the other.
