my car sounds like a tractor and is burning alot of oil making me think the valve stem seals were at fault.. got a fault code the other day of P0170 - Fuel trim..
previously when it started tapping i just topped it up with oil and it went away.. although last night after clearing the code it came back up again and the car started tapping very loudly.. so
i just checked the oil level expecting it to be empty but its full..
the car is dumping loads of fuel in on idle and when revving.. couldn't be tapping any louder.. its a 52 plate just below 50k..
seeing that the oil level is still high and its started tapping has confused me now.. i kno the above fault code can be one of a few things from coil pack, mass air flow or lambda sensor..
originally when the code came up i thought it might be the steam seals leaking oil onto the lambda sensor which has killed it..
but now its tapping but hasnt lost any oil
anyone got any ideas??
