Use mineral spirits (Stoddard solvent), MMO or Berrymans..do a couple of soak/run cycles (oci's) and see what that achieves? Let it soak for a day or so.. just be sure to change the oil out. Plus I would use a HDEO or some Rislone (abt $5usd) + PCMO during the oil change following a soak..the higher detergency will help clean things out better than an off the shelf PCMO.
