In my naive opinion i think it is not a fair observation. Even on a new plane the engine will not just be installed on a plane without being throughly tested. The heat generated by the exhaust and the afterburner will definitely change the metal colouring.

Nobody noticed that the J-10C is carrying a PL-10 WVRAAM and the J-10B is carrying a PL-15 BVRAAM?
My hypothesis is that since J-10Cs have more powerful AESAs (as opposed to J-10B's PESAs), the former need the more powerful Series 3 engines to more efficiently power the AESAs.

The thrust differential shouldn't make a difference when it comes to generating juice for the avionics. The upgraded engines were installed to improve its kinematic performance, plain and simple.
That is also why I suspect the J-10C, along with the J-11D, will receive the 145-kN WS-10B variant once it gets certified.

My apologies, Deino; I didn't see the file names.

I was not implying that should be the case. New planes will certainly be equipped with new, or re-manufactured engines.
To me, China has not ordered as many new batches of AL-31FNs engines as would be required for building new J-10s, maintenance work and replacing old, worn-out ones. So there must be re-manufacturing going on to maintain the number of engines at the required level.

Deino are you sure this is PL-15 in the second pic ? Because i remember when pic of 207 in Nov 2015 cameout with the exact missile hanging, you were unsure that it is PL-15 and you thought most probably it would be the folded SD-10 for J-20.
P.S. Your posts on Page 47.
Yes, I remember my posts then but now I think it is indeed something new. If it is the PL-15 or a PL-XX I don't know, but if You look at the nose section of both missiles and the size of the radome, I have the feeling, that it is a bit different to a PL_12.
