Glad to hear that he replied to you with some info and Im sure thought did go into this and he is certainly 100% correct about NOT getting any sealant in this area. The other problem with this though is that there is only a very thin area to seal between this passage and the open into hole under the intercooler, if you have seen the intake you know what I mean-Lee you probably noticed this. Not getting any sealant in the passage means next to none in this area at all, and garlocks need all the help they can get to seal. Take into account oil soaking into the gasket and breaking it down over time, oil "coking" if you will and blocking the small passage off. Not everyone tears their car apart multiple times a year to inspect and clean things and a 5 year run without teardown would really prove its worthiness. As mentioned earlier a bigger passage would be great but they did what they did because there just isnt much room to work with.
