My 305 TBI needs adult diapers...

[LEEVON]

I am on a mission to cure my '87 w/ 305 TBI of oil leaks. I hate them.

I started by replacing the oil pressure sending unit which was definitely spewing oil.

Still leaked.

Then I did the rear main seal (one piece) and the oil pan gasket.

Still leaked.

Thinking it might be the famous back-of-the-intake leak, I replaced the intake gaskets, and the valve cover gaskets too.

Still leaked.

Thinking I might have fouled up the intake install I did it again.

Still leaked.

Then I took it to the shop down the road to see if they could find the leak. He thought it was the rear main seal so I did it again. I found a piece of the old retainer gasket on the block, so I thought for sure I had found the problem.

Still leaked.

Then I found a bolt that was poorly sealed on the intake (there was oil pooled up) and fixed that. Thought for sure this was it.

Still leaked.

Then I replaced the distributor base gasket which had been done with the intake but it was discolored like oil was going out the back.

Still leaked.

Then I removed, cleaned, and sealed the dipstick tube.

Still leaked.

It only leaks after driving, and it's coming off of the starter. The back of the intake, sending unit, rear main, distributor, etc. are all clean. This engine is pretty clean and I should be able to see a leak.

I have had it on a lift, on stands, lights above and below, and the leak cannot be found but it's definitely on the back above the starter. To top it off, after driving it shortly today, when I parked it puked coolant. Could I have a bad head gasket, which is leaking oil down the back of the block, onto the starter, and now could be causing overheating?

Since everybody likes pics, here's the incontinent hunk of junk I'm talking about:
