BRABUS 3.6-24 engine startup after rebuilt

Hi there.

After a complete rebuilt of my brabus engine M104.980 in my W124

The engine has a very small ticking sound.

I have used 5W/40 oil, but BRABUS have mounted a specification in the engine bay, that states that only 10W/60 RS Oil must be used.
Why is that and could it be the thin oil im using that causes the almost not hearable ticing sound?

It getīs wors as the engine gets hotter.

I was also very much in doubt about the timing if this engine (have read the AMG timing thread) my engine donīt have extra dowel holes to line up with but I know brabus also stated that only Super blyfrei must be used, that means 98 Octane, and I can get the Shell V-Power here at 99 Octane, så that should be fine, but normaly this engine should be able to run also on 95 Octane right??? is has the KE Jettronic.
The resistor on the ignition module is 0 Ohm. = higest timing setting for best performance but this also meen I should run on 98 Octane witch I am.

Så this Ticing noice that getīs worce as the engine gets hotter, is it only because it has been totaly rebuilt or is it the oil 5W/40 I am using even though brabus say only 10W/60 should be used or is it my timing that can be off? please advice me or come with your best input on this matter.

Once my 104 did loud cam sound after oil cooler assemling.

I took valvecover and check each valvelifter by pressin them. Few of them was still empty, even after 2kilometres driving. So I knew wat was makin the soud. I gave little revs and sound was gone.

Thumbs up

I drove it for 10 miles to day, and after that the sound was gone, I pushed it quick up to around 4000 rpm. and the sound was gone.
So I guess that must be fine

But after a rebuilt you are a bit scared that something went wrong under assembly but engine runs veru smoth now and has a realy exelent idling.

Now I just have to adjust the whole ASR / Electronik Actuator as the idle is a bit high.
But that should be an easy job

thanx for the help and tips.
