I have been fighting a oil leak for a while however the last time at the track the monza stayed dry.What I found out was the milodon pan I was running is not engineered very well for a merlin three block. There is an indexing hole on the pan rail of a merlin three block that the milodon pan does not cover very well due to a tab missing.The fix was to buy a cheapie stroker pan and a good fel pro stroker gasket the stroker pan has the extra tab for the indexing hole. So far so good, now the track personal don,t have to swear every time I make a pass LOL
