    Hi, probably covered before but is it all engine codes that suffer with the cams wearing?
    or just certain ones?
    Mines a AYM, a little concerned!
    Also, got an oil leak from top of engine, very difficult to see exactly where. Any common leaks?
    Thanks.

    Take the rocker covers off and look at the cams, i have had cars with over 200k with no wear on the cams and cars with 150k on long life servicing which had cams changed ! Usually is oil retention valves not keeping oil in the heads overnight and longlife intervals/poor quality oils that kill these engines, they are good with regular maintenance !

    Thanks Chris, will look over next few days. There's no performance loss, just a slight noise from left bank to the rear.

    There are 2 oil retention valves, under the oil filter housing buried deep under the injector pump !
