no i have not mainy becuz i dont know where they areStep 1 is to remove the motor from car; the oil pan can not be removed with it bolted to the mounts and it is very difficult even with it lifted up. Another cause of leaks in the rear main area is the rear main bearing cap. Place a small amount of silicone on the block along the edge where the cap fits so oil can not seep through the space.
Have you checked the oil galley plugs and cam plug for leaking?
Make sure you diagnose it right. It would suck to pull the engine and find out it was the oil sender. Oil leak at the back of the engine is the manifold, valve covers or oil sender more often than it's the rear main or the oil pan. Clean it up real well and try to see where it's coming from before you spend the time or money on repairs.thanks for the pic i really like this stie you guys know your **** and are very willing to help there is no dust shild on the tranny so i looked up in there and i dont see oil on the flexplate or back side of the block so im starting to think its some other then the rear main im going to cheak the oil pan drain plug and oilfilter and oil line to the gauges
