Capt Alex,

Can you hear a sticky valve? I changed my oil this morning and when I started the car up after I was listening under the hood. There is a sound under the valve covers on each side that kind of sounds a little rough.

What does it take to fix a sticky valve (I assume its the lifter that is sticking).

Thanks for the idea, and steve thanks for the input. I know without testing I can't get any answers, I was just looking to know what kinds of tests can be done, and trying to get an idea of probable causes.

Thanks again and happy new year.
