Changed timing belt on 2003 Kia Sorento 3.5 ,Timing marks are lined up.Engine starts up and runs smoothly BUT has no power..? If the timing was off by one tooth,Would the car start and run smoothly and...


Being one tooth off on many engines will allow them to run well but lack power. In most cases you will find that the cam timing is retarded which changes the valve opening timing. When that happens, the engine will have gobs of low end power and will idle smoothly but will fall on it's face at higher rpm's. Race engines utilize this phenomenon to gain horsepower by doing the opposite and advancing the cam. That takes away some low end power but increases it at the top end. That needs to be done by "degreeing" the cam and is dangerous to do if you go too far as valves and pistons can crash into each other.

Hi i have a 2004 vwlt 2.5tdi when the engine gets warm theres a tapping/rattle from top of head i seem to be worse as you let of the throttle,no smoke or lost of power any suggestion cheers jeff


MOTOR IS NOT GETTING ENOUGH OIL TO THE TOP END TO LUBRICATE VALVES AND LIFTERS. POSSIBLE SOLUTIONS; OIL PUMP NEEDS REPLACED, ENGINE NEEDS FLUSHED, OIL AND FILTER CHANGE. BAD RESULT MOTOR WILL EVENTUALLY BLOW UP IF NOT ATTENDED TO SOON.

I have a 97 tracker that lopes at idle bad any ideas what it is


Could be a vacume leak. Need a vacume gauge. Hook up to a vacume port should be around 17-20 inch pounds of mercury (steady). If not this check your emissions system
