Can You Over-Tighten A Valve Cover?

Yes, it is possible for an individual to over-tighten a valve cover and damage the steel cover and gasket, causing the oil leak. While tightening a valve cover, once you notice that you have hit bottom, you should be careful as any more tightening can break the bolt tip into the head.  

If you have a torque wrench, use it to check the bolts’ tightness; if they seem a bit loose, you may want to tighten them. There are automatic valve covers set at a certain degree of tightness, and when you try to tighten them over the recommended amount, they can cause damage. 

The valve cover also differs in thickness; some require more tightening than others.

After dismantling the valve cover, it is always a good idea to check the valve cover bolts for proper torque. 

You may also find them over or under torqued; if you don’t know how to loosen a bolt and re-torque it properly, then do not try. You could cause more damage than good by using brute force to loosen or tighten a bolt or stud.

Tips for Installing Press-in-Place Valve Cover Gaskets

What Are Valve Cover Gaskets?

Valve cover gaskets are small pieces of rubber or cork that form a seal between the valve covers on an engine and the cylinder head. The valve cover gasket is usually located on the top of the cylinder head, covering the top half of the engine’s internal combustion valves. 

 Valve cover gaskets are essential because they keep oil from leaking down and pooling under your engine. This can lead to minor drips and catastrophic engine failure if left unchecked. 

Valve cover gaskets are also more susceptible to leaks when engines wear out, which is why often it’s suggested that you replace them with other maintenance work done on an older vehicle.

If you’ve ever worked on a car that has been sitting for a while, chances are you’ve had the pleasure of dealing with the dreaded valve cover gasket leak. There are three types of gasket materials used by manufacturers that do not affect performance or durability: cork, rubber, and plastic.
