Thank you for the reply, that seems to be the general concences around town, I took off the oil filter adapter and blew compressed air through the oil cooler lines and adapter all seems clear, the relief valves in the adapter seems to be working fine, used brake cleaner to clean up adapter and got the oil pan bolts off and froze my butt off laying on the frozen ground, tommorow I will finish taking it apart didn't know the front drive shaft would be in the way but all well, Thank you again I will keep you posted.
