Hit the 150k mark and it a clear sign that im losing way more coolant than I should and the mix of oil and coolant is apparent at the rear of the engine. At this point of time my gen 2 is my daily driver but in a few days I'll be able to have the luxury of driving a spare car while my OB can get worked on. the question is there any brand (felpro is a brand I off the top of my head) that will exceed OEM specifications? thicker material etc. I don't mind a shop charging me labor for installing the hg. Don't have the time to work on it. Also is there any other parts I should replace as well?
