Consumer Description

the vehicles experience excessive oil consumption because the defective valve stem seals allow engine oil to leak into the combustion chambers. This concern usually occurs when the mileage reaches approximately 2,000 – 3,000 miles (5,000 - 7,500km) and may also occur again after replacing or topping off the engine oil.
