All turbos are cooled and lubricated by the engine's lube oil.

You don't have to install an oil cooler.

does it mean that my turbo is both Watercooled and Aircooled. may IN-OUT kasi yung water and oil paths sa Turbo...

and does it need a turbo timer?

An air intercooler may help. This is located between the turbo's air discharge duct and the engine's air intake manifold.

thanks, may spare toyota 3c-tdi engine kasi kami, baka puwede ilagay sa aming 3c-td. hehe..

Oil is primarily for lubrication, water is primarily for cooling.

Oil is primarily for lubrication, water is primarily for cooling.

I'm still a bit confused sir Otep, other peeps differentiate the two... is there a Watercooled Turbo only and an Oilcooled only?

As all turbos are always oil lubricated, they would therefore be oil cooled as well.

However, not all turbos are water cooled.

See my post to Rion regarding water cooled turbos.

does the starex TCi hav both?

[Dieseldude]

I'm not sure if Starex TCi is both oil and water cooled. What is TCi?

What's the year and engine model of your starex?


I can check this out when you send me the above info.

Bye

yung Innova D4D ng brother ko -- oil cooled lang yung turbo

yung Everest ko naman -- oil and water cooled yung turbo nya

i'll post pics later para makita nyo yung difference.

If your turbo has oil and coolant plumbing, it is oil and water cooled. Oil primarily lubricates the turbo. Oil has a secondary function of cooling the turbo as heat energy is transferred to the oil, and further dissipated to the engine. Water cooling is sometimes integrated into the turbo design if it is expected to be used on high hp engines (more hp = more fuel = more heat).

and does it need a turbo timer?
A turbo timer may help. However, if the original design doesn't have it, you don't really need it. So why spend more?

Pwede rin if you want to try.

Hi Dieseldude,

A year ago every time my speed reaches 60 kmph, I can already hear my turbo whistling. But now, even I have already reached 120-140 kph di ko na naririnig ung dati nya na tunog. Is it because sira ung turbo? or may kailangan ako na check?

please advise.

Thanks.

I will not be concerned about this as you are hitting 120 - 140 kph. Power is good...........turbo is working fine.

Sir,

What's your take on the Bosch CRDi system Foton uses on their 4JB1 turbo motors? Have you had any experience with them already? Anything to watch out for? Are they expensive to service?

The View passenger van is available only with the CRDi engine variant.

I haven't seen a Foton, and have no experience on this vehicle. Things to watch out for would be the CRDI system installed.......is it a Bosch. Denso, or a China system.

I would next look at riding comfort and noise level. Without mentioning vehicle brand/s, I've seen some new China vehicles with excessive vibration and unwanted in-cab noise. Some even had poor transmission gear ratios.

Best thing is to test drive the vehicle.

The system is a Bosch branded system. Everything from the computer box to the injectors has Bosch logos on them. Are these systems reliable and easy to fix should anything go wrong?

I've test driven the unit. The extra long wheelbase (even longer than the View ambulance) really helps soak up the bumps. Vibration is a bit high. Sort of like riding a Crosswind. Shifter feel is not very sporty but tolerable.

25 years old ang FX. Bakit mo lalagyan ng new engine ang very old body?
Wala akong alam na makukunan nang bagong 2C. Try mo kaya sa Toyota.

sir ask ko lng po. ngpcheck po aq ng injection pump ko kc mlkas n s diesel (TD27 turbo engine) tpus ang sbi ng ng_aayos mlki n dw butas ng nozzle ng injection pump ko kya dpat ng plitan., sir dun po b tlaga un?! if ever un nga problem san po b ko pedemkbili nun. TIA & GOD BLESS

[junver]

sir dieseldude,
may nabasa po ako dito thread tungkol po sa mga diesel owner adding 2t oil sa fuel and they claim that the engine runs smoother. ano po ang masasabi po ninyo about this? makakasira po ba ito sa injection pump and fuel injectors in the long run? or talagang makakatulong po ito?
maraming salamat po and God Bless

Wala akong experience sa paggamit ng 2T oil. Hindi ako maglalagay ng 2T sa common rail diesel.

Meron kang bara sa fuel line mo between fuel tank and filter. Baka barado rin ang breather sa filler cap ng fuel tank.
