my c.r test is not related to the oil pressure or noise issue i was simply by coincidence going to do the c.r test before i removed the engine when i discovered this other issue

the idea was to check it before i go buying glow plugs filters oil belts etc and pull the engine to do a swap

no it wont start easy from cold because all the gp are dead... hence the c.r test
but now i have this odd oil issue

and i diddnt want to mess with it if the oil issue is a known,common big deal
