I am getting some (minor but annoying) oil leakage around the intake manifold on my '87 300dt and am about to replace the gasket. The leaking is around a couple of the runners where they attach to the head and appears to be the nice jet black goo that is coming from the EGR crossover pipe. It looks pretty straightforward and I did a quick search and found nothing special to be careful about. Is this as easy as it looks or am I missing something here? Also, I don't see any reference to a gasket on the crossover pipe to manifold joint. Should I use some sealant there? Any advice from those who have done this before would be very much appreciated. Thanks.
