alright guys heres the situation. I just a 99 ram 1500 ext cab 4x4 with a 360. its burning oil pretty bad and the guy i just got it from was running 15w-40 diesel oil when its a gas engine. the gasket under the intake manifold have not been replaced yet so thats the cause of some of the oil burning but its burning a lot and a lot of smoke comes out when its revved high. its blue to black and when i start it white smoke comes out till it warms up. it sounds like a slight tap or noise under the passenger valve cover. it also makes a loud almost grinding noise around 2000 rpms. I posted a youtube video of the grinding noise
Im doing a compression check and running the codes in the morning to check whether its a worn piston ring, or a valve stem but i dont know a whole lot about engines so what do you guys think?
