One of the most often neglected easy and inexpensive maintenance items I see on gas engines. Why do people think that spark plugs will last forever or that it doesn't matter what type of plug is used! Aren' they all created equal?
This is a VERY common maintenance item on the older Mercedes V8 engines. If they are too old they will leak. If they are not put on properly they will leak. If you do any maintenance (ie, valve adjustment, clip replacement, timing chain, guides, etc), you should have this kit on hand.
You can not believe how many problems Kent has seen over the years as a result of the camshaft oiler tube falling off inside the valve cover! It is held on by inexpensive small plastic clips and guess what happens after 15 to 20 years? Yes, that is correct.
Kent will show you the proper way to remove and replace a V8 valve cover gasket so you won't have oil leaks after installing a new one. This is a common maintenance item.
