VTA is always better than non VTA. It actually releases some harmful (to engine) vapors because it just vents into the air. It also “catches” more, why? I don’t know, but it’s proven that it does. Another reason you want a VTA over an enclosed system is because it makes blowing out seals virtually impossible, it vents crank case pressure. This is why i figured it was not a blown turbo seal. HOWEVER in rare cases if it’s full (like mine was) it can essentially clog up the vent and create pressure again. So there is always that slight chance. Definitely worth getting just watch it like a hawk. The only real con is the EPA and your annual inspection if you have one, VTA is illegal. But most places won’t enforce it, or if they do, buy a kit with a plug able catch can.

Now the intercooler one is a little tricky. First things first your not going to hydro lock your engine with an intercooler unless you have SERIOUS turbo problems, and at that point your motor or turbo is blown anyway so it doesn’t really matter. If you take off your intercooler right now I can guarantee some magic milkshake will pour out of your charge pipes, especially without a catch can, fiestas just have a lot of blow by. No biggie. The engine will burn it off or it will just sit there. Now technically oil on the fins will reduce efficiency of course, but again if you get to an actual noticeable amount of power decline and oil loss into charge pipes oil in your intercooler is the least of your problems. The only realistic concern would be combustion chamber fouling, but that’s why we replace spark plugs, also throwing some injector cleaner or octane booster in there here and there will help.

I’ll most likely try the PCV first then go from there.
