5 psi? Is that right? Seems ridiculously low.

 

Oil pump pressure and crankcase pressure are 2 different things.

 

I just remember old school engines, seems like they typically had 40-60 psi. So long ago, memory fading....

But then there's this. https://www.chevyhhr.net/forums/gene...c-video-61345/

 

I admit I was making up numbers. But, where can oil interface with water where the oil is higher pressure than coolant? Turbo and oil cooler.
The oil at the head gasket is on its way to the cams with relatively little resistance and it flows in the direction of least resistance. Even if the gasket somehow failed between an oil journal and a water port.

 

Any suggestions on parts to throw at it? What can I inspect? Can I take the turbo apart? Any lines around there going to it? The thermostat housing banjo bolt for the coolant line had no gaskets and was rusted. I'm wondering if there is other stuff along that line on the turbo that needs attention.

Where is the oil cooler located?

 

If it's the turbocharger, it will be internal. So, a new turbo.

The oil cooler is next to the oil filter.

 

And the oil level will be much higher! Is it?

 

I can't rebuild it? At all? Will a different turbo be rebuildable?

It's actually a little low. But there is a slow leak somewhere. I usually see about 1.5" diameter puddle every day. But the oil from the dipstick is yellow colored.

 

Maybe there's a rebuild kit. It's a k04 that's a zero, not an oh. Maybe could find a good used turbo.

 

So oil level isn’t increased by coolant leaking into the engine.
oil is yellow? Did you use Ford coolant? instead of Dexcool?
