Karl, Tracy -
when I first reached out to a Gadgetman about getting my truck done, I was in contact with Aaron Knorr here in Canada.
If memory serves, he explained he has a grooved 4 cylinder version of the Ranger/b-series, and emphatically encouraged me to put a condensator/AOS/catch can on mine. I don't think he's active here on the forum, but an email to him was answered with a return phone call in literally minutes. Really, Really nice guy, from our chat. I encourage you to reach out to him, Karl. He'll have more engine-specific insight than I into your groove and your issues.
