has the timing chain receiver been redesigned ? anyway good luck with your air con compressor and high pressure fuel pump and valve carbon buildup. also keep in mind rebuilt turbine cost 3k .
Tq for the highlights on Prince engine problems.
Just before I bought my 408, had done a lot of research on this engine. Was glad to note EP6CDTM (408THP engine) carries 8 mods addressing reliability issues found on the older Prince. All issues you mentioned have been successfully addressed. The following are the mods:
1) Engine tuned to run on RON 87 petrol
2) Remapped ECU
3) New designed piston with lower compression
4) New designed catalyzer.
5) New engine oil filter housing with heat exchanger
6) New turbo charger
7) New fuel tank gauge unit with lower pressure pump to handle lower grade petrol.
8) A fuel filter to cater for hash atmospheric condition ( third world country)
We've had a few HPFP defects. I believe these were qc issues as this engine carries the modified HPFP. I'm sure you know, qc is not a 100% check. These were possibly those which slipped through the net. No occurrence of failure after replacement. Note, even a fuel filter is added on this engine, to cater for our contaminated atmospheric condition.
Turbos are redesigned, more than a 100 owners registered here in this forum. More than 10,000 postings to date. Not a single complaint on turbo. Below are photos fractured turbo on older Prince. Turbo charger technology is constantly evolving. They are certainly much more reliable now.
Timing chain and chain guide were modified earlier to the introduction of EP6CDTM. Present line up of Prince 1.6THP - EP6FDT & EP6FTDM have been further refined to Euro 6 emission standards. Now that Euro 5 diesels are in Malaysia, I hope we are offered more diesel engine variants soon.
Facelift 308/508 in Malaysia are Euro 6 Prince engines. I believe we'll see more applications of this reliable Prince here in the future.
