I heard its called hydrolock when the engine is overfilled with oil. As bad as having no enough oil in the engine. Im not sure how much you would have to overfill to cause  this to happen though??

 

a LOT of Oil would be needed for this to happen, I've never done it, but I'd guess in the order of 20 litres.

It's a bit of a different case, but my car has a 3 quart accusump oil reservoir attached, which stores an extra 3 quarts of oil at ~80PSI (there's tube with a piston with about 80PSI of air pressure on one side, and oil on the other).

 

When I flick the ignition on, the thing releases oil into my engine so it's at around 80PSI, before the car even starts. As oil pressure comes up, it forces extra oil back into the reservoir.

 

In some cases, if I leave the ignition on and don't start the car, it could push an extra couple quarts into the engine.

That's pretty cool!

I could do with something like that. My cold start ticky noise wouldn't occur if I could just get a bit of a squirt of oil down the push rod holes early on. More of a workaround than a solution in my case I realise, but I would take that!
