There's a guy up in 04-08 stating he built up oil pressure before starting a new engine. Anyone know what he's talking about? Oil can be pre-loaded to the top end with air pressure but that needs to be disconnected before starting. That leaves zero oil pressure when starting.

 

The only way I have seen a modular pre-load is by putting it in flood mode and allowing it to crank over a few rotations. It's crank driven, so that is the only way I can see it is possible.

 

Flood mode is new to me. Can you explain this?

I use the Engine Quest version of this because it costs about 25% of this:

 

Maybe Ford has a different name for it. But I've always known mashing the accelerator to the floor while cranking as "flood mode". It won't allow the motor to start.

I have a 302 (1/4") and a 351 (5/16") oil pump primer that you use a drill to prime/charge the system. Works great!

 

Ok, that I get. The pressurized pump like the Melling is used for modular. With gearator oil pump they are the only way to pump oil in to the top end of the engines so they aren't started dry of oil. Seeing as the OP's question is in 04-08 he's not getting oil up with a drill through the distributor. He hasn't answered how he got the oil pressure up like he said he did without turning over a dry engine. If there is a way, I'd like to know what it is. lol

 

How does the gearator deal even work? I'm intrigued.

 

Wikipedia explains it better than I can.

Edit: As far as I know all modulars use a gerotor oil pump. I could be wrong about that though?

Oh, OK. I took apart the stock 3V pump, so I've seen that before. Just didn't know the name. I thought that Melling unit you posted was tapping in to something on the block to circulate oil or something.

 

The Melling canister I posted is used to pre-lube the engine. The oil pressure sensor is removed. The cannister is filled with oil and put under pressure with an air line. Open up the line and oil is blown everywhere in to engine. It's suggested to take the valve covers off so oil flowing at all the cylinders can be witnessed. Once oil is at that point it's gone everywhere in the engine. With the Coyote having oil cooling jets on the pistons the pre-lube is even more critical.

 

Although the terms often get mixed up there are also engine pre-oilers. The WRC cars had them. It's an electric pump that brings the engine to its required oil pressure before starting the engine. They are also available that will bring the oil to running temperature before starting the engine.
