Im going to change the glow plugs on my car soon, as I have an intermittent fault popping up, for cylinder 2 glow plug.
it all looks pretty straight forward to change them.
My question is, in the haynes manual, it says when replacing the cam cover back on to apply a bit of sealant in a couple of spots. I just want to know what sort of sealant i should use for this bit or if its actually needed.
