Yes Hello to all V6 drivers and of course all other Audi drivers. 🙂 I have in small problem that in the training run at 850 rpm and only when the engine is running warm my Ventiele clackers oil pressure is available enough 2.8 bar in the training run as soon as the speed is raised to 1000 rpm it is a little quieter but still available. I tried all possible oils from 0W-40 to 15W-40 with VW Audi standard of course. I also made the hydro-punch all new. n suspects about the thing that I can hardly imagine…. is that the camshafts have gone so far that the hydropumps can no longer make up for the game because yes the guide sleeve at the bottom of the hydropump is only up to a conscience measure with me it comes out about 1.5 mm through the oil pressure and thus the game compensates. and if this becomes too big it does not manage and it clacks. with a mechanical one can set it with adjust screw or insert Blättchen etc. someone already had such a problem or is there the possibility that these have entered or is there a measuring procedure for this engine? for wear limit of cams etc? with diesel engines there should be also such problems???? thank you in advance 🙂
