My 514 had been leakless for a long time but has recently sprouted various leaks. As I plug one up another shows up. This seemed to start after the intake manifold gasket (which was a mess) was replaced. It seems as though there is too much pressure building up in the case but I'm not quite sure what to do (or if this is the real problem). At this time I also changed from Royal Purple
Synthetic to mineral based Quaker State Racing 5W30. I have a dual
oil filter set-up and 9 quart pan.
Any suggestions would be welcome!!
Regards,
Josh
