> Hi all:  I had a cylinder head gasket leak, which pressurized the water
>tank.  The engine had 20,000 miles on it since it had new heads.  I've torn
>the engine down and didn't find any serious looking problems.  Now, while
>putting it back together, I noticed a keeper is missing out of one of the
>hydraulic lifters, and a chip is missing out of the top of the lifter body.

>        My question is:  Since the keeper was gone, would it be possible
>that this is what caused the head gasket failure?  My thinking is that
>because the keeper was missing it allowed the lifter to pump up way too far
>and pushed on the valve far enough to cause the spring to bind; thereby
>pushing out on the head, causing the gasket to leak.  There was no piston
>damage from the valve hitting.
