After reading all the posts about air leaks,i decided to tighten all the turbo,intercooler hoses etc,some were very loose.The hose by the firewall,all the way in the bottom,i believe air intake hose was fairly loose,i had to use a 8mm socket and a flex because such a tight area,after getting my arm out by valvecover,under the coils noticed some oil on my arm,anything to be alarmed of,car just hit 10k.
