you should do a compression test

Did you tune the idle , adjust injector offset, battery offsets? and play with IAC settings

No, but will try this morning. injector and battery offset? what's that to do?

Did you try replacing the pcv valve????????????????????

what pcv valve?

If I unplug IACV, rpms are 1-1.2k, but rapidly bouncy, no white smoke for 1-3min, then heavier. When plugged, rpms stay 2-2.3k, and gradually heavier`white smoke from exhaust. I'm thinking since new HG, and head with ARP HB's, disconnect coolant lines from TB and IACV and check start engine?...

What dou YOU mean what pcv valve? The pcv valve is a little valve with an elbow that connects through a vacuum hose from your block to your intake manifold. It's almost like a check valve. It relieves cranks pressure directly to your intake manifold(having a catch can would be better). On my most current setup, I had the same issue. Installed a stock Type R and it was idling high and smocking, a lot of white smoke. I would unplug the iacv and it would idle lower still white smoke coming out, but not as much. It's a $4 piece, most every auto parts places sale them. That would be a good starting point..............

Thanks, that was it!

What did the trick for you?

I thought the piece that goes through the IM was just a fitting that would easily come out. well it was previously broken so I took it out, not knowing, and ran a strait hose to the breather. I now know what a pcv valve actually is. I blocked off the intake mani, that brought idle to normal, and no more white smoke! I ordered a new pcv valve, thanks for your help! Ectune support is the best!
