so ive been helping my buddy fix some boost leaks on his truck and we are still getting a leak somewhere.
his truck is a e99, he swapped the turbo setup to l99.
i noticed on my intake plenums they used some sort of sealant to get a good seal.
when he installed the 3" intake plenums he just put a gasket in.
my question is, is the gasket enough?, or is sealant also required to prevent boost leaks.
we have verified intercooler/manifold boots are good. new int'l up pipes no exhaust leaks. new orings on the turbo (compressor housing, intake horn to manifold).
im stumped at this point, i told him to order a boost leak detector so that will be here soon.
