Question what to check...

what would be the first things to check if i am suspecting there is radiator fluid getting into my motor and burned up... causing white smoke out of the head filter/vaccumm hose...?

headgasket maybe bad?

Are you saying that white smoke is coming out of the valve cover?

Head gasket failure typically results in white smoke out the tailpipe, as it introduces water into the combustion chamber. I can't imagine how water could get from here into the valvetrain area.

How does your oil look? Is it at all cloudy or milky? Any slimy gray residue on the underside of the oil cap?

oil levels have been constantly giong down...most likely due to bad turbo seal, that problem is in the mail as we speak...

as for the underside of the oil cap everything looks normal...

kinda frustrated with this.

dip stick. Is it milky looking? Radiator do you see oil in it when you take the cap off?

burning oil can look white in some cases....are you saying you shut the engine off and you see smoke exit the breather filter and oil filler hole?

Didn't we already cover this:
https://www.miataturbo.net/forums/sh...ad.php?t=10044

If you suspect that you're burning radiator fluid or have a leaky headgasket... THEN JUST CHECK YOUR RADIATOR FLUID LEVEL!!! If it's low, then fill it up. Drive it for a day or two and then check again. If it's low... THEN IT'S LEAKING!!! If it's full, then it's not.

If you want to know if the radiator fluid is somehow getting into the crankcase and mixing with the oil, THEN JUST CHANGE YOUR OIL AND LOOK AT IT!!!

You also said you're blowing oil past your turbo seals with just a filter on the crankcase.
You should ventillate your crankcase to just after the AFM/MAF to reduce pressure in the crankcase so you know there is no resistance in your oil drain.

i've already done hat cjernigan, i am awaiting my turbo rebuilt kit because my turbo is effeedddd...

so as of now yes, i am running the breather hose to right before the turbo helping to seal the seals better.

to be ordered....
mazda 323 PCV
i'm tired of waiting to get one of these, i'm gonna do it.
new headgasket... how long does it take to take the head off and install one?
i'm almost positive that it's bad, and this will help me rule the headgasket out of possible radiator fluid in oil.

why not just do a leakdown test then....you can be 100%, some sort of smoke out of the valve cover is probably ring/valves or something letting the combustion into the crankcase.

You're going to need a leak down test kit. I don't know if the parts stores that let you borrow tools have them to loan out or not... But look around, perhaps someone like Harbor Freight carries an inexpensive kit.

The procedure is straight forward. You introduce pressure into a cylinder @ TDC and see if it holds or not. If pressure leaks, sometimes you can hear where the air is escaping from.

did you test them wet and dry, at normal operating temps, with the gas pedal at WOT.

Depending on the failure, it's possible. Bad HG will more likely blow air into the cooling system. You'll hear the radiator bubble up.

I don't know, I've never had to do it. The question is WHY did the HG fail? And if it did fail, is there additional damage? If it's just a HG, you'd be lucky. Unfotunately the block is iron and the head is aluminum--which both expand at different rates, usually resutling in the head warping.
