I need to replace leaking valve cover gaskets on the wife's 02 Yukon (5.3). How involved is this and is something I can handle in the driveway in an afternoon or weekend?
If you can put injectors in an lb7 5.3 valve covers will be a walk in the park.. They are pretty simple. Just unplug and remove coil brackets, remove valve covers.
I haven't had the pleasure of replacing LB7 injectors yet, but I have put on a y-bridge on my LBZ. I have pulled and replaced an engine and am inclined to tackle it.
