Toyota D4D engine woes

[larshell]

As I just found-out, this is exactly the case why you need to idle turbo diesel engines after long drives... But, the D4D problems are injection pump related and not turbo related, as per owners affected.

I agree wd you my problem wd my Innova is not related wd Turbo i also ask my SA just to be sure.

is that the reason why they recommend letting the car idle for at least a minute after running at high speeds? to release pressure in the intake? isn't the car engine doing that always, also through the wastegate?

isn't it that the main reason is to let the turbo cool down by using the oil circulating in the turbo's bearings to carry heat away from the turbo? if the oil cooling the turbo bearings kasi get hot, it sort of degrades and will eventually gum up/coke the bearings, eventually destroying the turbo diba?

Idling the engine for sometime before switching it off, the main purpose is to cool down the engine including your turbo especially if you have just subjected your engine to high speed. In fact, a minute for me seems not enough. Should be at least 3-5 minutes to allow the oil and cooling water to circulate more and absorb more heat generated on all moving components of the engine, The oil lubricating and cooling the engine internal parts and for the turbo bearings are all coming from one sump. Oil degradation will not only be caused by the turbo but by all engine components as well. Most turbo failure is due to insufficient lubrication caused by poor quality of oil being used.Some oil tend to lose their viscosity when subjected frequently to high temperatures.Synthetic oil is the best for turbocharged engines due to it's high temperature resistivity, oil like mobil 1 synthetic oil which can withstand temperature of up to 250C as they claimed.

So every D4D has to idle for 1 minute at the gas station before killing the engine & fill up.

Yup! For turbo diesels, dapat pag malapit ka na sa gas station, coasting ka na lang at below 1500rpm, para kasama na sa 1-2 minutes count yun. When you reach the gas station, stay muna sa may tabi while you idle. Once satisfied that you've cooled down the turbo, you can then approach the pump and turn-off your engine...

Ang hassle naman. Parang may ritual pa bago mong patayin ang makina.

well... talagang may pros & cons ang diesel engine.

you get huge gobs of torque down low with the help of a turbo... and in return you must make these small sacrifices to maintain the turbo.

Yan ang trade-off for getting a more powerful turbo diesel engine...

[BlueBimmer]

having an intercooler helps though

[bilog]

get the vvti na lang kung ayaw nyo ng hassle...

I went at Toyota Balintawak yesterday to fix my garnish problem and my agent talk to me about the CRDi parts. Good news my agent told me, Thousands of CRDi parts have already arrive and distributed to sub-supplier.They are aware of the problem, i think. I call Toyota QA and there still this one tube na kulang pa sa mga parts.My unit is not included wd the allocation.They also told me that they are expecting this problem wd CRDi w/in 120K ODO reading it so unfortunate daw it happen so early Meaning i only have 120,000km. before my CRDi will have this problem again after they fix my CRDi. Warranty expires at 100,000km. or 3yrs w/c ever come first. Also they told me that in other countries earliest that this problem occur is 20,000km. on ODO reading.
I suggest to all D4d user to use it daily at least if problems occur w/ur D4d under warranty pa and you have another 120,000km to run.

tama ka bro, its better to use the unit as much as possible so that any crdi damage can still be replaced under warranty

or sell the vehicle kaya lang nakakaawa naman yung buyer and i guess it is up to the seller who knows about this problem to level with the buyer

thanks again larshell for the info. waiting na lang ako for my 2.7vvti, next na raw ako.

re d4d problems, mahirap din kung abutan ka ng engine trouble sa malayo at deserted na lugar. i usually use my car 70km/day, 90% highway driving so i need a durable and worry free engine. also, baka mamaya may makisabay na client sa new car ko tapos ayaw naman mag-start. diyahe na, perwisio pa...

I talked to a friend of mine from Isuzu Philippines Corporation. The same problems occurred with the initial release of the Commonrail Diesel on the Trooper. Injector problems caused several units to malfunction din daw (they attributed it to poor fuel quality). I asked him if, with a different engine displacement, the same injectors can be used. No, daw... I'll have to confirm this with someone from Toyota, but, I guess magka-iba ang fuel injectors and denso pumps ng 2.5G & 3.0V. As, there is still no actual 3.0V owner complaining, I will assume (for now) that the problem is limited to the 2.5G fuel injectors and pumps. But, as someone here suggested, I'll have to be wary of my D-4D engine's behavior and where I go.

Hindi injector ang problema ng D4D.

[vicoyski]

It isn't? So what's the problem then?

Di parang sinabi na rin ng Toyota na gamitin na ng gamitin ng mga D4D engine owners ang ride nila kasi mag se self-distruct yong mga engine nila at 120K ayon sa toyota. Loko din ang Toyota ano? Binigyan pa ng alalahanin ang mga D4D owners dahil isipin mo ang range na binigay nila na pwedeng masira ang D4D engine nila, from 20K-120K. Ba, mahabang palaisipan yan para sa mga D4D owners.Baka payag silang palitan ng VVTi na lang yong mga nakabili ng D4D. Haba ng pinila mo tapos ganoon pala ang mangyayari. Magaling palang maghuhula ang Toyota motors eh. Kaya sa mga nakapila, VVTi na lang kunin nyo, ala pang 20K-120K na palaisipan. Sabi ko na at may alam ang Toyota Indonesia kaya di sila nag benta ng D4D engine sa indonesia maski mura ang diesel sa Indonesia. Haayyyy

Thanks for the said info.

It looks like my Fortuner pull-out was a blessing in disguise.

it would seem that the problems (as of this date) in the d4d occured mostly on innova owners. Meron na ba isa sa inyo who owns or knows someone who owns a hilux na nagkaproblema na sa d4d?

Ang problema ,ngayon okay pa D4D engine mo, pero sabi nga ni larshell at toyota mismo ang nagsabi, may range na binigay between 20K-120K expected nila magkaka trouble ang D4D engine.Kung di ba naman loko yang Toyota. May peace of mind ka non?
