I beg to differ. I don't think this whole episode has proven a thing, which is typical of this religion of compression testing and the action taking after you get the results.

First of all, these engines don't normally burn valves. Whoever keeps saying that is flat out wrong. It sounds to me that all that was needed was to blow the debris out from under the valve that was not sealing. Once the compression came up on that cylinder, who knows what the oil consumption would go to.

And the idea of spending $600 and many hours to "fix" a possible non-problem is a huge problem in and of itself, not to mention if it's worth doing to a $1500 car.

What is needed is smart troubleshooting and better advice on these boards.
