Can anyone help please. We have a TD5 on a V plate. It has a genuine 50k miles. Been running fine until a couple of days ago when it started to misfire and run really rough. Have read various bits of info on the net and have spoken to Landrover Mechanic who says it sound like the wiring harness.
We have taken out the connector that clicks into the the front left hand side of the rocker cover and it was full of oil. There was also a lot of oil on top of the rocker cover appearing to be coming from where you top up the oil. However the cap to this was screwed down really firmly. We have sprayed the connector with a carb cleaner and it does seem to be a little better, but its still not running properly. We cant get the rocker cover off as one of the bolts has been rounded. Could there be oil leaking inside the rocker cover and into the connector. Or as we have cleaned the connector out could it be something more sinister such as an injector. We are hoping not. We are not mechanically minded but dont need a big bill at the moment.
