Ratty tat tat under the valve cover.

Good morning again ??

Rick and Gary, you hit the nail!

After an good cup of strong cafe I moved to the snake nest.

Checked the replaced roller rocker and desmantled it. Not much amused about the resulte.

This means, I have to controlle all the rockers on the engine. Nice sunday morning work.

Yes, thought so.

Now you need somebody to help you rebuild the valvetrain correctly, with better quality parts.

No way to wait until Sunday - full of curiosity!

Mounted the better rockers back into the engine incl. one spare I got.
Adjusted valve lash and started the engine.

No more noises, but at higher engine temperature noises were starting again fortunately with less "chin chin chin"-noise.

So I took the rockers out at the passengers side. All rockers have a light diagonal movement in the trunnion bearings. One of those in a bad condition.

The two bad rockers were at cyl. 5 exh. and cyl. 1 int.

This would make sense regarding the noise located at front around the distributor area.

I think it will be time to think about what has to be changed and replaced.

I might need some help, as I have to order the right parts because of the high transport and Spanish custom / import taxes. 35-40%! depending on the day, if it is sunny or rainy.

For now I want to thank you all for your kind help and I will be back with this topic lateron...
