I have a 1984 Toyota 2.4 L (2366 cc) 22R engine in my Okanagan motorhome. I need to change my exhaust manifold gasket as it ticks rather badly when I throttle it up. I can feel the air leak with my fingers. Any tips? Anyone done it? Pretty straight forward? Any potential gotcha's? I am trying to decide to tackle it myself vs getting a shop to do it. I purchased the gasket already.
