Is there a noticeable oil trail behind the rear-wheel-drive car? Can the police still tell 10 minutes later that the old Opel drove by? If so, the valve stem seals are often defective!
Depending on the specific engine type and model year, these stem caps are either mounted only around the intake valves or seal both the intake and exhaust valves. These valve stem seals are top-quality products from Reinz!
