A few days ago your engine was ticking and we helped with that.It has also' clunked' and now it has new noises? But you have never acknowledged resolution of any noise we helped diagnose or suggested remedies for.Perhaps I missed it?
For the current/previous noise, you posted no video/sound, no other diagnostic info as requested , no part number as requested previously, no details of the engine rebuild. We may be able to help with diagnosis but we need data .Otherwise our suggestions are mere clairvoyance.
A very useful tool for these problems is an "Engine Ear" -no, not a long screwdriver or a piece of rubber tube nor a stethoscope - a purpose-made electronic tool to locate noises precisely .
