TS, biar betul. If I hear the signature teppet sound, I know it's a Campro engine nearby.

How many top overhaul due to that? Taxi drivers will be the first to tell you Campro engine is 'weak'.

Campro might just be good enough for those who service and maintain their engines well, but once you use them in high heat environment (like fitting in NGV in taxis) or don't follow maintenance schedule religiously, problems crop up.

Compare that to the older Mitsubishi engines used in the old Saga, Wira or Waja or Toyota engines, especially when NGV is used, Campro has what I'd call, lack of engineering margins.

I'm not an automotive guy but I have both the old Saga with Mitsu engine fitted with NGV and the facelift 1st Gen Persona (with the IAFM).

I really love the Persona, one of the best looking Protons before the Geely comes out, it has really aged well.

When I send my trusty old Saga for tuning with the NGV specialist, I heard a lot of horror stories about Campro engines when using NGV. The money saved from fitting NGV is used to pay for engine repairs, sometimes not worth the hassle or cost, some taxi drivers with Campro Protons would rather use petrol than NGV.
