It is not uncommon one or both of the exhaust manifolds to crack resulting in an exhaust leak. Symptoms will begin as a ticking type noise noted on acceleration when the engine is cold.
An abnormal noise may develop from the timing chain area, Our technicians tell us it may be necessary to replace the variable valve timing camshaft shaft sprockets to correct this concern.
A clunking or popping noise may develop when driving over pot holes or rough roads, the front coil springs may be the source of the noise. Our technicians tell us updated parts are available to address this problem.
