Hello Tim,

The three most common sources for oil that leaks onto the exhaust manifold 
or into the lower shroud are:

1) Pushrod tube O-rings
2) Top cover gasket
3) Oil cooler

You can find out which source(s) is the culprit by removing the lower 
shrouds.  You will want to thoroughly clean off the leaked oil.  It may be 
necessary to do this first if there has been a long term 
leak(s).  Hopefully you have an easy fix and not too much mess.
