59 AB drain tube in rear main cap

[Bored&Stroked]

I do not believe he should have any issues - given the later rope-type seals of the 59AB. Of course, this assumes his rear-main seal is in good shape and doing its job.

Given that he dropped the pan and reinstalled it and NOW has an oil leak, the most likely cause is that a gasket has slipped or was installed wrong (probably the cork one on the top of the rear-main cap). He will need to pull the pan again, make sure everything is squeaky clean, use a set of new gaskets and use a gasket sealer to make sure the gaskets are correctly located and will STICK where they are supposed to be. I use something called 'Gaskacinch' (sp?) - which Edelbrock and others sell.
