After $2000 spent, looking for an educated ear or opinions on a highly frustrating issue with the timing/balance shaft chain on my 2003 95 Aero.
I had these replaced back in April and since only drove < 1000 miles. The main issue was from a broken balance shaft tensioner.
It appears the problem came back. Very noisy rattling under timing cover.
Seeking a consensus opinion before I take it back to the Saab specialist.
Below are two videos, before and after (note they are the same engine; I just repainted the valve cover and accessories since fix)
Before (check 1:17 as its more audible):https://photos.app.goo.gl/fXy1gEDGAwVfMeu57
To me, they sound similar, only now the noise is much more audible and occurs immediately at start-up.
I've checked the tensioner and its good, well within tolerance as expected.
I've run without the serpentine belt and noise is still there. Source is from timing cover somewhere middle down where it's most audible.
As this may require a repeat removal of the engine to fix properly, I'd like to exhaust all possibilities and avoid a possible confrontation with the mechanic. Hopefully it wont come to it, but this appears to be a redundantly costly proposition.
