I have a 2006 passat 2.0 turbo. When the engine starts it makes a rattling, pinging noise rough idle but the idle on the tach is fine. I replaced the PCV valve and the valve cover gasket was leaking so I replaced that to, but I still get that loud noise what could this be???
it's more central. sounds close to the rocker arm but I've checked that and nothing looks loose or broken
yes. after replacing the breather crankcase it was better for about an hour. then driving cause it to start periodically again. now it seems to be more when i'm driving and will try to smooth out when i'm stopped or parked
no possibility its the oil pump for the turbo??
