My rocker gaskets are leaking something terrible. They weren't really leaking at all, but I got out of the motor one day and could see smoke, plus it was absolutely reeking. Opened the bonnet in a state of mild alarm, to find oil trickling down from the back end of the rocker gasket onto the exhaust manifold heat shield, from which was burning off to great effect. It uses hardly any oil, so I guess it looks worse than it is, but for good practice I need to do the replacement.
Still, I'll miss the way people turn round with that "is it going to explode?" look on their face.
