Need help guys. Don't seem to have any vacuum. Just reads zero on the gauge. Haven't tried boosting it. Hotpipe on turbo isn't getting hot either. Any ideas? Could it be a vac leak (no whistling noises though) or a sensor?
This issue is not always apparent. Sometimes OK, other times not.
Did a quick search, but couldn't find anything on this. Are ARP head bolts different size tool than stock? Are there any markings to determine if they are indeed genuine? Anyone ever reused a stock set of bolts? I believe they're torque to yield, so have to be replaced?
Looking for recommendations for replacement stem seals, or are Toyota ones still the best? Prices vary massively online, from £15 a set to £60 (Toyota)! I know you get what you pay for, but on the other hand, OEM prices are massively inflated.
