Thanks NGoma, I noticed the bubbles thanks to some very very small stain-spots (engine oil?) on nearby dry parts that were a bit dusty too, so they showed a couple fresh `dots`on them.
When it comes to leaks, I`m OCD+paranoid,
so I immediately searched for a while then tracked down those bubbles being at the base of first injector.
It did look like there was `boiling` going on. Nothing crazy, just 2-3 small bubbles visible. I should have taken a sample onto a paper towel but I was on a long trip and there were no wet injector lines involved (nor a hard fuel line being loose). By the time I got home...I forgot to re-check.
You are right, it can be some liquid `boiling`. Good point -- because recently I had to realize that my engine oil cap seal is not perfectly sealing. There`s no other liquids there, like coolant etc, car hasn`t been washed etc. I need to check another connection though, as i do have occassional atf dripping below the PS which could* `travel/fly` to inj when vibration&speed combine with winds. Also, minimal amount of motor oil finds its way down on the passenger side of the block; coming from the cap on top. I guess.

I found what you wrote,thx.
You will want to perform the troubleshooting routine at idle where you loosen one-by-one the injector line nuts at the injectors and see if any do not lower or worsen the idle. This to find if there is a particular injector, line, valve, distribution valve, cylinder, etc. that is the problem. Do not over-tighten the injector line nuts when closing them up. 25Nm / 18ft-lbs.
What`s the best injector removal tool?One day it`ll be needed anyways so I searched this:
