993 Turbocharger Oil Line Update
Porsche 993 Turbo smoking upon start-up?
TurboKraft's oil line update package is the solution to this common problem!
The most common reason a 993 Turbo smokes on startup is the turbochargers siphoning oil from the engine after shutoff. Rarely is the smoking at start-up due to worn out turbochargers, oil draining back into the turbochargers from the crankcase, or worn valve guides / stems seals.
History and Technical Notes:
The 911 Turbos from 1976-92 and 2001 onwards were all equipped with components to counter this problem but the Porsche factory did not originally equip the 993 Turbo models with components to stop oil flow on shut off.
This problem was briefly addressed on the last editions 993 GT2 Evo models, but strangely not on the 993 Turbo road models. Instead, Porsche issued technical bulletins instructing dealer technicians to install specific oil filters to a specific torque value – which does not solve the problem.

We have developed this package to be a complete, direct replacement and highly reliable system for the original turbocharger oil feed lines.
Installation involves simply replacing the original equipment oil line assemblies leading from the engine to the turbochargers.
