Well i have only a few first when m driving and im really punching it with boost (90 tsi) at about 4500rpm i can hear a kind of crunching noise comeing for the tach and the higher the tach goes the louder it gets (last time i tested out the noise my timing belt jumped and burned holes in 2 valves) so i dont really want to test it and the weird part is it only happens when i get to 7psi at 4500 if i stay under 7psi there no noise. Next problem is im blowing smoke at start up (blue/black) as well as in first gear (black) im guessing it is the valve seals but i just replaced them with all new one back in may( by a professional machine shop) so how could they be going bad now, lastly i think my turbos on its way out but not sure i dont hit full boost until about 5grand and usually with a mbc installed i still cant get over 12 psi on a cold day (hot days cant get over 5psi) so i think the turbos dead but not sure (before my timing belt jumped i could get 18psi at 5000 so could it be a timing error) PLEASE I NEED GUIDENCE.
