Both reports could be true.

The Indians could be importing the turbine blades and the hot section from Russia while making the cold section in India from the metal.
Turbine cases are forged as well. So do not assume forgings are for the high temperature part.
The hot section is the difficult part since you need high temperature alloys, crystalline blades, and precision manufacture.

If you cannot make proper high temperature parts you can still try to make a jet engine. But the engine lifetime and performance will suffer.
Remember the Germans in WW2 made engines for the Me-262 which had like a 10 hours lifespan.

From what I understand the Indians had a license to make several engines. Not just the MiG-21 and Su-30MKI engine. But also the SEPECAT Jaguar engine and others. But I do not know how much of each of those engines was natively manufactured.

Unfortunately, making some parts vs. making the whole engine are not the same at all. For MiG-21, the Sino-Soviet split meant China had to pursue the R-11/13 on its own. India always had great access to USSR assistance. China was never granted any license for Al-31 and limited technical assistance. India was granted the manufacturing license. China had licensed the Spey from the UK, which is from a similar era to the Adour. What have they been doing all these years?

Makes me wonder if China had the same privileged access to Soviet and later Russian miltech as India had, would the indigenous ecosystem in China still be where it is today? And conversely, has India been hampered by the fact that it never was forced into a position where they had to innovate for themselves to the same degree?

To illustrate the superior quality of Indian defense firm HAL, I present you the evidence provided by this OSINT and fellow Indian himself:

It is easy to ignore this but up to and including the 3rd generation of aircraft the airframe losses were way more frequent than they are with more modern airframes. Engines were more unreliable and fly by wire was not available.
This is also the reason why the Soviet Air Force chose the dual engine MiG-29 over a single engine aircraft. High MiG-21 airframe losses because of flameouts of the single engine it had. MiG-27 is another single engine aircraft with similar engine family.
Add to that the fact that a lot of these Indian aircraft are being pushed way over their design lifetime and accidents happen.

Blaming HAL for this is kind of ignoring the facts.
