ARC Calsonic and Greddy Intercooler review, PCV Oil blow by issues RB26dett

My ARC intercooler was delivered crushed from Japan. FED EX and BlackHawk Japan will not cover the damaged and I may be screwed on this deal and have to eat the cost to purchase another intercooler. My car had lots of oil blow by in the system from over boosting and PCV blow by. I comparing the Nissan Skyline GTR stock calsonic intercooler vs the ARC brazing intercooler and Greddy intercooler. These all fit the Bnr34 bnr32 bcnr33 intercooler. The ARC intercooler appears to be built with the best craftsmanship and quality. When you turn up the boost on a Rb26dett PCV oil blow by can be prevented with a oil catch can. I have a NISMO oil separator coming from Japan in December. My Gear #rhd
