thank you guys for your ideas

filters are ok, I cleaned my intercooler that is under SC 3-4 months ago, I dont think it would get such clogged for such a short time. besides the cooler no leaks. yes I've taken off my manifolds for several times, but I tested them carefully when putting on and when searching for leaks. I'll test them again these days with another method and I'll post if I find any leaks.

what is your sc rpm and what boost are you making?
