Changed oil to penrite HPR 15w 50 and knock disappeared however it looks as if it may have been a prelude to a larger problem. Last friday while on the freeway in Sydney the pajero came to a grinding halt with a loud scraping noise coming from the clutch area, later when at workshop it was suspected that a spring may have dislodged from the clutch plate however this was not to be, the pin holding the clutch & pressure plate in had seized and could not be removed, hrs later and with much persistence & (swearing) the mechanic managed to remove the whole assembly with gear box in one piece.
What was found was that there was rust or corrosion on the pressure plate & pin that held everything together, Oil had been leaking into the housing from a rear engine seal. This can be checked by removing the rubber inspection cover on the clutch & pressure plate housing & putting your finger in & finding a thick greasy mix of oil & dust. The next discovery was that the flywheel has a bearing thats like (we think) a one way clutch or bearing, were not quite sure because its totally cactus and has 2 large rivets holding it in place hopefully we can acquire the bearing only and not the whole assembly also it looks as if the clutch & pressure plate will need to be replaced as thy have been cooked with the aid of oil leaking in. This after the vehicle was in to a mitsui dealer for a recall to re direct the a/c drain from top of gear box to the side. The ramifactions if not attended to may be total malfunction of clutch.
Has anyone come across this, coments would be appreciated especially regarding the bearing in the flywheel which seems to be odd especially if it doesn,t have a long life, Vehicle k's 244000 however this problem could have been going on for a while and the bearing in the flywheel is not easy to diagnose.
