Good guess as to cause. When they drop off a short block you probably will have to use your oil pan. Take a moment and check the crank end play. If excessive I thought you might have heard it but these diesels are noisy.

The BS seems everywhere today. I have a pending litigation issue myself to the tune of 100k+. The more they tried to rectify the original situation they created the worse it got.

They also did it on one previous job but we were able to work around it. These regulatory people actually scare me as to their negligence and incompetence.

They have no actual hands on experience but make decisions that over ride common sense and convention. Give idiots power and you produce powerful idiots and proficient lie fabricators.. An average guy off the street would be more competent.
