In the last three months I have noticed a leak on my garage floor. I installed the H55 a year ago and had the oil galley plug fixed at the same time. It is leaking more and more. I got under the truck and took a picture. Can anyone tell me what part numbers I need? In the posted picture the oil drain plug is opposite where I circled. The plastic part circled is half broken and the oil is leaking out of there. Thanks!
