In 2014 we drove just 2 rounds of the 5 rounds season of Time Attack. There was a slight cooling issue and it was puffing blue smoke in cold conditions. Compression was on the lower margin of the OEM specs... So maybe the turbo setup was asking to much from the KLZE after 5 years on the track
So on to the engine rebuild.
All assembled
Removed the bumper
Removed the radiator, intercooler, oilcooler and more
Removed the inlet manifold and discover one of the problems with the positive pressure inside the sump and overflow. Leaky valvestem seals...
The oil on top of the valve itself (the greenish bit) doesn't belong there! The black smudge on the sides is normal.
The Turbosmart wastegate, looks nice! No signs of rust of wear
Exhaust side of the turbo, no problems there
Inlet side of the turbo, looks sharp. No feelable wear on the shaft
Were we at..
There she goes
Empty engine bay
On the engine stand
Leaky oilseal on the crank..
Removed some bits
Left head, nice and clean, not dark brown, no signs of heavy wear
Right head
Ready to get the valvetrain disassembled and the heads removed
