I believe many premature turbo failures are because of neglecting to let it idle for a bit before engine shutoff after hard driving. This must've been the cause of numerous problems with Accent CRDi cabs and ignorant cab drivers, the reason why there are so few Accent cabs running around nowadays despite them being relatively new.
Hyundai CRDi's are actually quite successful. Many Starex CRDi's are still running around, most likely with high mileages already, and they are one of the first mainstream CRDi's sold here, besides the problematic Isuzu 4JX1. It hasn't become notorious for any particular problem that I know of besides normal wear and tear or abuse and neglect.
All our gensets have a cool down period of a maximum of 2mins. And out of tens of thousand of units sold only 2-3 was prematurely replaced... Kahit na nga units that are 30years old or units that are made in China... Kahit pa hindi regularly maintained... Lifetime tumatagal...
Sa experienced din namin the moment na nagleak na yung turbo Kahit ilan beses Ka pa magpalit ng repair kit.. Paulit ulit na masisira.. It's suggested na magpalit nalang ng bagong turbo....
oil starvation or complete stoppage of oil flow will result to early break down of the turbo charger. kahit repair kit replacement/repair basta maayos at "balance" ang rotor assy hindi basta basta mag oil leak yan assuming of course na ang casing is good and the repair was done right.
