84 Sunbird Leak when hot

[Paul94Z28]

Hi-

My 84 1.8 turbo leaks profusely from the oil pan/block/pump joint when it gets to 180. It does not leak if the temp is below that. I run 20w50 oil.

I have done the pan gasket 4 times and that does not appear to be it. I recently replaced the oil pressure sending unit and the pressure is normal. Sending unit is dry.

Any thoughts would be appreciated.

Thanks,

Paul

It was the Oil Pump. Once it heated up, the seals let go.
