How can I tell if my oil change valve cover is bad?
During most oil changes, the technician will inspect the valve cover to see if there is any leaking oil coming from the valve cover gasket. The quickest indication of this problem is when the valve cover/cylinder head is very dirty. Oil collects dirt and debris under the hood and will appear to be “caked” on the valve cover or cylinder head.
When does the valve cover gasket need to be replaced?
There are no maintenance requirements for a valve cover gasket. It only needs to be replaced if it leaks. If a valve cover gasket is old, it’s also often replaced when doing a major engine repair.
How much does it cost to replace a valve cover?
In a simple in-line 4-cylinder engine, the valve cover gasket replacement may cost $90-$175 parts and labor. In a Subaru “boxer” engine with two separate valve covers, a dealer or repair shop may charge $145-$360 for parts and labor. Replacing both valve cover gaskets in a V6 or V8 engine often involves additional labor.
Can a leaking valve cover gasket cause smoke?
Yes, a leaking valve cover can sometimes leak onto your hot exhaust system and will cause some smoke and a possible burning smell. We recommend adding 1 bottle of BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/) to stop your oil loss. You can expect to start seeing results after about 100 miles of driving.
