V6 24v camshafts lobe wear
I have seen 4 V6, two 2.5 and two 3.0. In three of them lobes look good, without any sign of wear. But fourth one (3.0) has eaten almost all lobes on all camshafts. I've replaced all camshafts and all tappets and after 40000 km you can see that the lobes are worn again. It's interesting that the lobes closer to camshafts wheels look worse. Both oil level and pressure were always good. Does anyone know, what could be the reason for that? Oil gallery is blocked? I've never had any problem with knocking tappets. Any suggestions?
