Why are my valve covers leaking?
The valve cover is typically mounted to the cylinder head through a series of bolts and a rubber gasket. Some engines do not use a gasket, but instead, they use silicone sealant. If the valve cover becomes loose or if the gasket material fails, the oil will begin to leak. Most valve covers will start leaking slowly without any effect on the engine.
What causes oil leak from valve cover?
One little crack in the valve cover gasket will cause oil to leak through and fall onto other components of the engine. There could be oil falling onto the exhaust pipes or cylinder head, causing the oil to burn excessively.
What causes valve cover to crack?
The valve cover gasket is a thin strip of rubber or cork that creates a tight seal between the valve cover and the cylinder head. Because the gasket is delicate and prone to damage, continuous exposure to dirt, debris, and heat over time will cause it to become brittle and crack, losing its ability to prevent leaks.
Why are valve covers leaking out bolt holes?
As mentioned before, the most common problem with inexpensive stamped steel valve covers has historically been that they leak. In most cases this is caused by tightening the bolts too much. Early cork gaskets compress quite a bit and that can fool you into thinking the bolts aren’t tight enough.
