Sorry if this has been covered but I’ve searched and couldn’t find anything.
I have an oil circulation problem sight glass stays full when running , unless engine is cold it clears every now and then.
I’ve changed oil, oil filter and attachments, oil cooler and hoses. Been in the sump strainer is extremely clean. Changed oil pump although just remember didn’t change o rings this time. But actually have no idea now like I say sometimes when cold it clears fines but once at running temp it fills back up. If someone has any idea please send recommendations thanks for reading
