I recently found a leak between the downpipe and turbo I assume it is the gasket, and I am also smelling some sort or exhaust/oil smell on startup it only smokes every now and then but not alot, also I am burning about a quart of oil every 2 weeks I use syntec 10w30, Im wondering if all this can be caused from this leak between the turbo and downpipe and if that is robbing me of boost?
