Once again, a complete load of BOLLOX!!!! Fact is, a turbo will still give 100% boost even if the oil seals are shot. Its only when the bearings collapse that both the seals AND the compressor wheels/housings suffer - at that point forget a turbo recon - its new turbo time... All a catch tank will do is separate the oil from the breather system - ie masking the problems! Catch tanks were designed predominantley for race cars that threw oil into the breather system under hard cornering... Do you drive a race car???? Didn't think so...
