Re: Collapsed Lifter Syndrome

Dear Gator:

Before you condemn lifters, consider these additional causes of your symptoms:

a) Sticky valves caused by corroded stems and guides.

If you think you have a lifter problem then pull a valve cover and check the action from underneath the fender. If you have a lifter problem you should be able to get a feeler gauge under the fully closed valve. Also lifter collapse will be visual.

Somewhere in the Packard manuals they state that your compression readings are most likely caused by to little valve lash, thus I would suspect a sticky valve. Even when hot.

Good luck with your car
