Exactly. It is both. External moisture more than the pcv but both combined.

It is oil droplets forced out of the crankcase. Other content in the crankcase vapor can form condensate, but the oil droplets are just falling out.

Frankly, I don't care or expect everybody to get every little detail right. It is still possible to follow the train of thought without nitpicking about such things.

QwkTrip

Yes, sir.

The downside of the oil is it just doesn't go away. At least water will evaporate and clear out in short time. The oil just accumulates in a pool and then some day causes problems. I can see why some people prefer to add a drain hole to intercooler. I would prefer not to, and given my history I won't need to. But if I was a person with chronic issues I would probably take that step.

No. I had little to no sludge in my factory IC, maybe a tablespoon at best. I plan on removing and cleaning my Wagner once a year. My driving habits and climate fortunately for me are not as conducive to the moisture issue as it is to others.

That may be the route I take. I had zero water in mine but did have some oil.

Doesn't matter, all engines with a PCV valve burn the oil vapors from the crankcase, the path they take is immaterial. The ecoboost does not make more vapors than any other engine.

The intercooler is a big damn catch can.

The problem is that one of the flow paths (while under boost specifically) is for the vapours to hit the CAC and condense.

Plus the engines of old were port fuel injection that cleaned the valves. Not direct injection. The ecoboost is not the only company with this problem. Look at the BMW forums.

Sorry the last bit is off topic and this isn't for agetech per say . But the condensation is an issue and with a couple solutions it becomes an non existent problem. You just have to get over the mentality that if Ford wanted the hole/can there they would have put one on from factory. Aftermarket products are used to enhance a product. Majority of people will trade off their vehicle before any valve coking becomes an issue and most will never make the near perfect conditions to cause a shudder. Even the way you drive can prevent the shudder, be aggressive on the gas regularly and don't cruise at a constant speed for a long period.

Out of curiosity how is the stock intercoolere constructed? Typical construction is air passes through tubes and cooling fins are external. I've not seen a cutaway of Ecoboost intercooler though.

vozaday

Not a cutout but gives you an idea. This is why I replaced mine. Lol
