zeault Posted March 29, 2022 Share Posted March 29, 2022 Hey, I am having an oil leak on the drivers side of my engine. It is getting all over the side of the engine and the 2nd/rear oil filter. It also sometimes leaves a little spot on the ground. At this point I am pretty sure it is seeping past the gasket of the oil filter itself. I have ruled out other areas by cleaning and checking multiple times (if you know a better method let me know hah). This has happened with two different oil filters from two different non-Mack brands. I checked and cleaned the gasket surface but it’s fine. Originally I was just tightening new filters as hard as I could with my bare hands like I do on cars, but then I tried tightening it a little more and it still leaks sometimes. If I tighten it any further I’ll probably have to cut it off because it’s so lubed up on the outside by the time I change them. This doesn’t happen all the time though. I think it is when I start cold and the oil is thick. I don’t have a block heater so every start has been cold. I also must admit that I don’t give it more than a few minutes to warm up. I start it up, pack my bags, check the lights/tires and go. When I drive it cold like that, the oil psi is around 60 at idle and 70-75psi at 1300rpm. Is that too much oil pressure for the filter gasket? Am I causing this problem by being impatient? Or is this an indicator of something wrong inside the filter housing? It only leaks from the filter that’s closest to the cab. The other two are perfectly clean. thank you for your suggestions, Jared Quote Link to comment Share on other sites More sharing options...
