New hhr owner. How big of a job is it to replace the valve cover gasket
 

I would like to replace my valve cover gasket myself of it's a job I could do in maybe 5 hours or less....has anyone done it? Was it easy?

Easy 10 minute job. But why? Tightening the bolts should stop leaks.

If you’re gonna do it, don’t go cheap the gaskets, get a kit with the grommets included. It’s not a hard job , you’ll need a 10 mm socket 1/4 or 3/8 drive a 6” extension and ratchet. Some wrenches a 12, 13 and possibly a 15 mm .
