| Per Garretts comments to me from their tech that is normal to have air get into the "casing" of the CHRA. There is only a ring and gap to seal and if direct pressure is passing through and over that ring you will get air going up through the CHRA and out of the in and out feeds. This again is coming from Garrett..not my thoughts or views on it. They specifically told me that he feels that 95% of the problem is due to crank case pressure. No matter if your bench testing or not your going to get air in that casing. That is what was told to me today on the phone. Again I have no problem in having Garrett inspect the turbos as they will do that for me for free so if you want that done get ahold of me. But it is VERY unlikely that BB turbos will blow in under 100 miles.
