800 miles the passanger side started smoking, i looked in the IC pipes and there was oil, so the turbo seal went out. I called turbochargers.com and they were trying to say that the problem might occured in the install of the turbos. But i remember that, when they installed my turbos they put new oil lines,gaskets and they prime the turbos. Best thing you can do is buy jwt500s theyre your best options if your on the budget, also go under SEARCH and youll find a lot of useful info on rebuilding turbos, hope this helped.
