Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hello, my name is***** you tell me how many miles are on the vehicle. Has the timing belt ever been replaced?
Thank you. If the timing belt is still fine then most of the time the issue is either from the lubrication system or the cam timing actuator. I am sure that you have done this, but make sure the engine has a new, good quality oil filter and the correct weight oil. If that is fine then it is more than likely a bad actuator. I usually monitor the cam and crank signals to see if they correlate as one or the other, usually a bad cam sensor, will read incorrectly and cause this.
Yes. If the computer commands a change in valve timing and the oiling system is not functioning right then this will occur.
