    Can you not avoid ethanol laced fuel? It will corrode your fuel system and clog the injectors eventually.

    In M50, the valve cover gaskets go bad, these can cause oil to leak adn air to get in- also, many pipes and connectors under the intake can go bad over time. I replace all mine on both M50s, was well worth it.

    Perhaps injectors or FPR. Is drivability perfect at all times?

    Ethanol is everywhere here in kY with no labeling-no choice. Valve cover gaskets only had a small leak when I changed plugs. No vacumn leaks. my indy and I checked and repaced at least one hose. No help
