Should I replace both valve cover gaskets?
I've got a leak that I'm dearly hoping is just a valve cover gasket, and not a cam shaft seal (yay vvti). Based on a clean up and diagnosis, I'm pretty sure it's a valve cover gasket (the bits of gasket coming off of it didn't hurt that conclusion). However, only one side is leaking.
My question: is it better to do both sides, or is it better to let sleeping dogs lie on the side that's not currently leaking? With. A lot of the older engines I've worked on, the answer has been to not disturb a gasket until it failed, but wanted opinions on the toyotas.
