I had my car at the mechanic for a burning smell and was told the valve covers are leaking (again.) I replaced the gaskets a little over four years ago for the same reason. I'm surprised they are leaking again so soon. Is it normal for these gaskets to give out after only four years? If not, how long should they last? I know I've got to get them fixed, so what is the recommended brand of gaskets and that other stuff? I forget what it's called but I remember there being some kind of sealant that forms another gasket that has to be scraped out and reapplied. I found a guide on here for how to do it myself but given my ability, I'm leaning towards letting the pro handle it.

But that leaves me with a couple of questions, as well. The estimate I got was for 2.8 hours of labor at $125 an hour plus parts. Do those numbers sound reasonable, or should I be looking for another shop?

I think I'm posting here for advice as much as I am peace of mind.

Thanks in advance.
