ok this one has got me stumped !!! 10mins of driving at no boost (ok you know thats hard to believe but it is the truth) 2500rpm ALL of a sudden there is 911 of Thick Blue smoke rolling out of the tail pipe 3000 rpm ok 1500 rpm ok 2500 rpm not ok any boost no smoke . now this all started after i parked the for 3 weeks do to freezing temps (didn't want to drive it in the salt) . and i can induce it by pulling hard left hand Gs. . This motor was a full performance rebuild and has less than 7000 km on it . it was broken in on 14psi boost for 3000km and now live it life at 22psi for street and 25-27 track . the S60 center was not overhauled but was ans still tight no sings of coking at all but it did see some wicked high Egt's and survived 3 CAC pipe blow offs before i did the over haul
Things i have done
1. pulled the plugs and inspected normal
2 pulled the hoses on the intercooler and inspected for oil none
3. revamped the PCV system for better oil collection and better Crank case breathing/ventilation no effect but now i gained 2"vac at idle for total of 20"vac
4 removed the plugs again and put bore scope down the bores and inspected cylinders look good but there was oil in the piston dishes all 4
5 remove header dump plate of shoved my bore scope up to the turbine blades some oil but not that much (might be burning it off)
Things i still need to do
1 leak down test
2 remove my Fm 475 cam and swap in my roller s60 cam (this was going to happen before this ) and inspect my valve seals
3. see if i can get my bore scope down the TB and down the ports of my 2 piece intake and look at the valve stems for oil
4 see if can get the turbo out for a possible overhaul(need to try and do this last as i need this car bad right now)
