some days ago, my Baja starts to have a loud knocking noise from the engine, also to feel on th clutch-pedal, occuring while accelerating. I took it to my subaru-shop and they found some metal-chippings in the oil and for sure there are one ore more bearings broken, probably crankshaft, as ist is feelable through the clutch...

So i hooked up a new shortblock and oilpump and let it be swapped. After starting the engine, the camshaft-sensor failed too, and has been replaced meanwhile.

But there is still a problem: engine starts fine and also is fine while cold. But when temperature reaches about 70° Celsius, it starts to idle bad, CO reaches 10 % and cylinder 1,2 and 4 are much to fat. Nobody in the shop and at Subaru Germany has any idea what the prpblem could be!

Everything possible, esp. ignition-parts and IAT has been changed without result.
Any idea? Anyone?
Regards and thanks for answer,
