Puffing White Smoke, any help would be much appreciated

Bill,
Understand. I'm making a relationship between white smoke, ruff idle, high oil, coolant level. Historically thats a HG, but from what I'm reading here the intakes are more likely than HG's. Suppose these symptoms could also be an oil overfill causing oil foaming leading to a ruff idle, and the smoke is actually on the blue side.
 


I'm not disagreeing at all. I think the possibility of the oil overful/possible air is something he should address tonight.

HG's without a very serious overheating are almost unheard of, experience points me away from it most of the time. Intakes do leak,... experience on that to leak externally you will hardly ever see oil unless it seeps up the bolt and sits on the LIM (which doesn't cause smoke) and coolant would do about the same. Coolant might make its way into the lifter valley. To do that though..would cause frothy oil. Most of the time though..the gaskets just look bad and we make a big deal about nothing too large.

Let's say it's an HG and list out how the failure could effect things.
HG isn't going to leak oil 99.9% of the time because it's only there to lubricate and isn't under pressure. Being that it's splash as I'll call it and then draining back to the crankcase, it shouldn't be enough to cause any issue and he's high not low.
Coolant could go into the cylinders and he'd be seeing smoke out the exhaust pipes, not engine bay.
Coolant could leak externally, he'd have a leak/puddle from it. Shouldn't be any smoke because it'll run down the block and not hit the exhaust.

Next thing we should probably ask is.. Last tune up, last TB cleaning etc.

I'm totally on board with you though.
 
Like I said I had planned to do a tune up this weekend or so, waiting on a check to come to have funds for the car. Was planning new plugs/wires and throttle body cleaned
 
After letting vehicle cool down, I did what you said let it run for a minute, checked oil on dipstick, looks the same as it has every other time, not milky or frothy.
 
Sweet smell indicates the presence of antifreeze being burned. Next time your under the hood. Look to the right of the engine by the intake side and look down towards the bell housing. Looking for the presence of any dampness or staining from antifreeze. If you look into the valley between the 2 heads, you'll see the intake. Chances are you have the LIM failure and coolant is making its way out and dripping on to the exhaust manifold. Here is what mine looked like when I pulled it off.

Also look for signs of wetness around the intake manifold bolts.
