I need some information about a top end knock. Can anyone tell me what to look for or what could be causing the knock. I think it’s responsible for a oil blow by as well.

Hello Mitchell803, welcome to the forum.

Have you checked your engine oil level? You may have a bad injector, putting too much diesel fuel into one cylinder? Where are you seeing the oil blow? Out the crankcase vent line? Or out the exhaust?

Get the engine knocking..
While it’s running, loosen the injector line AT THE INJECTOR.. & see if the knocking stops.. if not, tighten the line up and move to the next.. keep doing that until you find the cylinder responsible for the knock..
Then pull that injector out and have it tested or simply put it in another hole and see if the noise follows the injector or stays on that original cylinder..
Good luck.
