Its a good thing to listen to your mechanics advise, After my engine was built, It developed a oil leak, Its a plastic oil sending unit that take 2 minutes to replace, After I drove home and saw a oil leak in my drive way, I was upset, when i called coyote engine rebuilders, They said to have your engine properly diagnosed to find the oil leak, Autozone has oil dye to determine where the leak came from and ziggy took the UV light and showed me. These guys did a great job on my diesel and im very pleased with how they handled my vehicles engine rebuild.
