Rb25det Clouds Of White Smoke

[pergolaman18]

Hi all

My rb25 in my 31 is blowing white smoke and it pours out if you revv it abit.

Has perfect compression
Just replaced head gasket, head was machined, pressure tested, vacuumed tested
Inlet manifold gaskets replaced
No milky oil in sump or head
Turbos in good condition ( I doubled checked by unbolting it at the manifold and you can see the smoke and some liquid coming straight from the right port on the exhaust flange on the exhaust manifold so it's not coming from the turbo )

I'm out of ideas can someone please shed some light??

Do a warm dry and wet compression test. Also do a leak down test.

If you're saying it's coming straight from the exhaust ports then I would definitely say it's got nothing to do with your turbo unless it's leaking through the seal into the compressor side!

Also check your breather setup - make sure your pcv isn't blocked or any parts of your crankcase ventilation setup!
