Hi Ric,

        Others will be able to help more. 

Describing the sound, and also any other changes like loss of power or not might help. 

I did have my rockers on my 1.9 come loose after some work was done on it back in 2018.  We had to replace some push rods and a few other small parts and tighten correctly.  

I hope you find it. 

Eric
