When your Buick GS 400 left the factory, it was destined for a driver who wants a trusted name in their automobile.
Reducing harmful hydrocarbons and noxious gases that come from your car or truck depends on your use of properly functioning exhaust and emissions parts. No engine is 100% efficient, and each one (even the one on your Buick GS 400) needs a system to control positive crankcase ventilation with a working PCV valve. Usually located on your valve cover or cylinder head, your Buick GS 400 PCV valve is a one-way valve that receives the escaping exhaust blow-by from the crankcase and routes it into the intake. This is much better than simply venting it into the atmosphere, which is what all engines did before they were equipped with a positive crankcase ventilation valve.
