I have a sport 500's and they only have about 1500-2k miles on them (bought new).
I broke the motor in using 20w50 regular oil, and then once I hit 1k miles, I used Mobil 1 10w30.The car didnt smoke through out the whole time i broke it in.
Once it was broken in I hit full throttle boost @ 14psi, it didn't smoke until AFTER i got off throttle. A plume of blue smoke
(can smell the oil too...)
Drove it for a few hundred more miles, and every time i boosted - same issue??
Oil pressures were regular, water temp regular, fuel was nice and rich (ash ecu)... I just pulled my motor, oil all around the OUTSIDE of turbos (both sides), just a mess, a layer on everything around the turbos. Also, I found oil in turbo in intake compressor.
No shaft play (aside from the standard minute amount). I assume its the turbo oil seals, how can they fail so soon? One thing I thought of was that when I installed my nismo oil cooler, i deleted the factory hoses, and used -8 an hosing from the cooler directly to the oil tree. Would the loss of restrictors, and the slightly larger hose affect the oiling system? Compression on engine is good... Also, who should i send my turbos to to get inspected, possibly rebuilt.
Anyone reputable besides JWT, i've come across some names over the years, but dont remember any names.
