done a boost leak test today. found 4 leaks. huge leak on intercooler coupling, one on my bsh pcv fix, one on my maf, and one on a little pipe next to the pcv. i also found one on my rocker cover gasket. should i replace the gasket.
now the car still peaks at 23psi and holds bout 17-18psi till bout 5500rpm then drops down to about 12psi. does that sound normal or should it hold 18psi to redline.
also after i done my boost leak test and started the car up it smoked loads. i didnt block the rear pcv off though so thats proberly why. hope it hasnt done any damage.
