Some background: Had my engine (4g63 NT) overhauled since Oct 2021 due to leaking gaskets, for the following months I keep getting back jobs since the shop was very incompetent (Wrong belt timing, blaming parts they purchased etc.). So after my 3-4 back jobs my Galant became an embarrassing smoke machine that spits enormous white/blue smoke on idle and every rev, the incompetent mechanics said that it's just spitting the last few remaining oil stuck at the exhaust, but boy did I not believe their terrible lie.
The valves were bent, the head had clearance issues and the piston rings were leaking! (They even broke off my trunk badges, scratched my paint and broke my gauge RPM!)
Forward to Feb this year, I found a better shop that fixed the last job's crappy mistake, they machined the head, resurface valves, adjust valve clearance, replaced valves and seals and replaced some of the piston rings, (I didn't had the budget to fully replace all rings and the piston sleeve since they said that the pistons had some play but said it can be solved by just replacing some rings), the car smoked a little bit then it was FINALLY gone.
BUT the timing was off (bucking when off throttle and pressing 1/4 of the pedal) so the next 2 days I gave it back for them to adjust the timing, they fixed it thankfully however THE SMOKE IS BACK and it's just as bad as before!
So the question is, did the wrong timing caused the engine to break the valves and the rings again?
