Hey TECHIES ! just a quick one for my own info, glow plugs, where are they ?? are they accessible?..do you ever have to replace them at some point?.. normal maintenance..tks, bc

They screw into the head, they are just above the exhaust manifolds. Normal replacement is not required.

Is there any chance of these plugs ever breaking internally (as one person with diesel knowlege) so pointedly stated. He recommended changing them periodically. ? Whats your thoughts? Appreciate the info, regards, bc
