Clean starts.
Cool oil.
Parked, a 993 Turbo can let oil drain into the engine and the turbos, then smoke on start-up. On my car one-way valves keep the oil where it belongs, and a bigger cooler keeps it cool.
01 / TOP FEEDS
Check valves at the turbos.
After shut-off, the turbos can siphon oil from the engine and push it past their seals. TurboKraft’s feed lines (993-107-030-TK) carry check valves that stop the flow when the engine stops.
02 / ENGINE SIDE
The anti-drainback kit.
FVD’s anti-drainback kit (FVD20799320) puts a one-way valve in the engine-side hose between the oil tank and the engine, so a parked car keeps its oil in the tank.
03 / LOWER LINE
The Rothsport valve.
The lower line carries a Rothsport oil inlet check valve (RS-29B). Rothsport builds it for the 1995–98 993 and 993 Turbo to stop oil migrating from the tank into an engine that sits.
04 / CUSTOM LINES
Made to fit.
The lower lines are custom-made AN lines. They bring the turbo oil back along the factory’s looping route.
05 / COOLING
A bigger cooler up front.
The left fender’s factory cooler made way for a CSF 8119 bar-and-plate cooler in Euro Parts West’s kit. Euro Parts West rates it at 64% more core surface than the original Porsche cooler.
Its -16AN lines run to the factory GT2 cooler that stays in the right fender.
06 / OWNERSHIP
One oil system.
