Hey I appreciate the help. I change the oil and looked at the oil for filings. I dragged a rare earth magnet through the oil and found nothing. The tractor is relatively new to me. The weird thing is is when you turn at the right front wheel rubs against the oil filter and spins off the filter . So I知 gonna have to devise a guard to protect that from happening again. I gave the engine another complete oil change end it seems to be running smooth without any issue at all. This is my first diesel engine and I知 not that familiar with the clocking noises. After dumping 4 L of oil on the ground and driving about 50 feet before I knew it I was fearful of a destroy the engine. It seems I may have been very very lucky. Again to all of you thank you for this blog.
