No symptoms that I know of, but I didn't buy the car new so I don't have a benchmark for that. I did it more because of what I've read and it was time to replace the valve cover gasket.

Now I do notice a difference after the change. More low end power around town and I swear it seems to rev smoother. I will have to wait a few weeks to measure gas mileage, but I will do this and report back. So far I've only done about 40 miles in town so the seals still have a ways to go before they are fully bedded in.

Cheers,
Donovan
