got a oil leak on my 67 camaro equipped with a 05 ls2. oil is leaking between block and bellhousing, because it has a keisler hydraulic clutch I ran a dye test in the engine only.The dye showed up in the leak so I pulled the tranny,bellhousing,clutch and flywheel thinking it was the rear main seal or cover plate,they both appear to be ok and there's no oil on flywheel although there was sign of wetness on front of the tremac and hydraulic clutch bushing also a pool on oil in bottom of bellhousing. but the dye test shows engine oil,no sign of oil from valve cover gaskets or anywhere else on back of block any suggestions?????
