Short of tearing into the engine and removing the valve springs, is there any way to test whether the valve seals are bad?

 

Blue-ish smoke on start up is usually the sign of bad valve seals. There really isn't a way to test them.

 

Why do you think your valve seals might be bad? What are your symptoms?

 

pull your plugs. it helped my pin point exactly with one was bad.

 

Good suggestion. Thanks.

As to why I think they might be bad, well, I have oil smoke on start up, but, as explained in my other thread on that subject, this happened last winter for a month or so and then just went away. No more smoke on start up and no oil consumption between oil changes. Now it is happening again, 8-9 months later. I do not think valve seals go bad and then fix themselves for almost a year and then go bad again.

This is why I am looking for a way to test them.

Thank you one and all for your input.
