Hello, I have such a strange problem with the 1.9tdi bls engine.
I decided to replace the hydro tappets and the roller bushings.
Everything went fine.
Timing on the foot locks tightened 8Nm + 90 degrees and the axis of the injector levers 20Nm + 90 degrees.
And unit injectors are adjusted, i.e. the lever is pushed in as far as it will go.
INA glasses and new camshaft bearings.
But when folded, it knocks more than before the exchange. The engine was idling for about 20 minutes and about 10 minutes at 1800 rpm.
The timing is set well and the synchronization is
-0.89 as well as before the exchange.
Do you have any ideas why he is knocking?
The sound comes farther left from the valve timing. I would like to add that the frequency increases with the revolutions but does not knock louder
