Hi Guys,
Was going through other forums, and stumble upon this statement made by a fellow forum-er.
"
The Prince THP engine is notorious of problems. From the carbon buildup due to its less than stellar direct injection, to turbo failures, to depollution error, whatever the f that means."
Can anyone verify on this matter? And elaborate more on the issue highlighted?? I mean, i've heard good things about the new THP163. All the issues from the 308T was rectify and modified on the 408T's engine.
Is he referring to the THP156 engine used in 308T??? Or maybe he still think Pug engine/electronics are still like previous models??? Hmmmmmmmm

Hehehe.....don't get delirious bro. I've done extensive research on the Prince engine and will put an end to all your fears! I think you'll owe me a couple of beers for this info!
The person who wrote this is obviously not an owner of a Pug. I can say this from the statement he makes,it's a cut and paste of the Prince engine problems. If he was an owner and experienced the problems, he'd surely know what depollution problem is.
1st rule of thumb.....don't blow your fuse on what is said by a non owner! These jackos are just cut and paste kings!
Now, is the Prince notorious for engine problems.....yes! I will not deny this and it still is! By now your blood pressure must be rising. Cool,cool bro,the notoriously problematic Prince engine is the THP 140. Premature carbon buildup, takes place as early as 20k km. This triggered depollution error signal. Turbo units on this Prince have failed due cracked pressure outlet. Photo of the cracked turbo unit below. Remember this one was on the THP 140. HP Fuel Pumps have failed.
Then came THP 156, was much improved. ECU was retuned which solved 95% of the problems faced on the THP 140. I believe prolonged passive driving habits contributed to a certain portion of the problems on the THP156. Personally I've not been satisfied on what was done here, since a direct approach was not taken to rectify reliability issues. ( this is only 2cents worth). ECU retuned to solve some issues is actually an indirect approach.
Finally the THP 163, the engine on 408t. Redesigned all components with reliability issues. 8 mods were carried out towards reliability. Here's a summary:
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)
Redesigned pistons make a difference in preventing premature carbon buildup. I did post sometime back,the effect of the new design and how this exactly works. If you need to know more details, just back track. Turbo unit completely redesigned,no more craked units complaints.
EP6CDTM on 408 has proved very reliable. Right now the new 308,3008 and 408 are fitted with this engine. Would not surprise me to see greater use of this engine. I have posted the 8 mods previously,am glad to post again to bring about greater awareness of the reliability of this engine.
Finally
"less than stellar direct injection" is the panicle of nonsense! He obviously has no clue this engine is European Engine of the Year Award winner 8 times! This statement declares those European panel of judges non credit worthy!
You still think this guy knows what he talking about!
