Toyot 2.0D Hot Starting Issue

I mean DISPOSABLE car lol

3000 km oil change?? who told you that.

any engine oil of today will work for 5000 kms. I am seeing such silly comments on PW everywhere that people change their diesel engine oils every 2000 or 3000 kms because it gets black. Oil colour is not a gauge to verify the oil condition. If you do wish to check via colour then drip some onto a white porcelain tile and see if clean oil bleeds to the edges of the oil drop, if it does not then the oil is bad.

to keep black soot level low in the oil - it is vital to time the engine properly and keep the engine at operating temperature.

^ Really???
Then it will deficiently cost very less then a petrol engine as the mileage of properly timed and tuned (I don't understand it well because i'm class 1 student in diesel engines :P) Daihatsu charade gives more than 22 kmpl. If it's true, then it's not very expensive.

They say pakistani diesel is very dirty, change your engine oil after 5000km in UK and maximum 3000km in Pakistan. My col (r) uncle owns a Hilux (new shape) and he changes his at 3000 kms and happy with performance. Here the diesel turbo charade is an older engine and can work better with dirty diesel they say.

I used to own a 1.6 turbodiesel VW Golf in Pakistan, that car used to return between 22-24 km/lit easy, engine oil used was usually caltex Delo 400 15W40, changed at every 5000 kms along with its oil filter.

Even at 5000 kms the oil still was clean by the tile test. The running condition of the engine was that it had the oriignal 89 degree thermostat in place, filled with coolant, original Victor Reinz Headgasket with new bolts. The original crazy powerful cooling fan setup. The gauge was always at 60% of the sweep no matter if I was in Karachi in the summer or Quetta in the winter.

If you fulfil all operational requirements of the engine it will run like its supposed to, So if you are running your engine with no thermostat and complaining of low power, oil sooting up and expensive running you yourself are to blame.

I still drive a diesel here in the US, its a mercedes benz E300D, 3.0 6 cyl DOHC 24V diesel and I get about 13 km/lit from it. oil changes every 3500 miles along with filter and 85 degree thermostat in place cooled by Valvoline Zerex G-05 (MB coolant), the engine only makes its smooth quiet power when its hot, running it cold literally feels harsh.

Now when I read that a toyota 2C in a corolla returns 10 km/lit I find it hard to believe unless the engine smokes black all day long.

Dear Xulfiqar Bhai, I am at home now and checked cold start advace plunger and observed it that when it is cold it extends about 3 to 4 mm and I feel increased RPM and when engine coolant temp rises to its limit then this plunger retracts back and RPM are reduced. so I feel that it is working, Also I flushed my radiator and filled it with caltex extended life coolant and distilled water (50/50) as I got your suggestion on Radiator related thread, so now what else needs to be looked at regarding hot starting issue as the problem persists when it is hot I have to crank almost 3 to 4 turns as I feel then engine starts. but very nice when it is cold in the morning.pls., advise

Good!
Today I talked to a mechanic in cha sultan, he said that you need to repair front suspension after every three months :0 if you put diesel turbo engine in it. And it'll cost 6 to 7 thousands after every three months because diesel engine has more weight :o
What do you say about it?

[Xulfiqar]

3 or 4 revs of the starter are considered OK for a diesel engine, my mercedes does that too, it starts on first turn every morning but takes 4 revs of the starter when warm.

Good that your CSD is functional - make sure that you keep it that way.

Thanks a lot! Now I feel that the engine is in good shape, I will check tappet clearence when I will find time to visit Toyota.
If your Benz starts like this then it is nice as mine is not a turbo and very old as well. Thanks I got many ideas from this forum

[Xulfiqar]

my benz is not turbocharged.

The weight of the charade petrol and diesel engine is the same, the only problem is that the diesel one virbates and needs stronger mounts which the G10 chassis does not have the provision of. The G10 charade is pretty solid IMO and is about on the same level of complexity as the G11. So the suspension rebuild thing is pretty silly IMO.

I would suggest you keep the diesel in good shape if it starts up correct, revs nice and is not noisy from the bottom end, you should make sure the crank timing belt gear is not loose on the crank nose because it can literally destroy the complete engine if the belt loses timing. Meanwhile look for a good CB23 engine from a G10 complete with original gearbox and axles to put in your car if your diesel engine shows signs of torture. Because Im pretty sure for 70,000 you must have got a car on its last legs.

Thanks 4 help I'm not getting this car because it's in very bad shape too much body work I don't have time to do this. However, if I find a good condition G11, diesel in good condition around 1 to 120,000, I'll consider it.

my benz is not turbocharged.

Alright, but Xulfiqar bhai do you see the starting of Ford super duty how fast cranking it has, I was expecting the same from 2C when it is hot but It takes little hard cranking when hot that was a question for me.

[Xulfiqar]

the starting up of an 8 cyl engine cannot be matched with a 4 cyl engine, there are twice as many firing pulses per revolution and the Ford also has quite large displacement per cylinder compared to the toyota 2C

Just like when you hear a V12 start - it sounds like the engine has no compression.

Thanks, Agreed, I start now my 2.0D without any fear or hasitation without waiting for preglow timer to finish. I will keep writing and asking on different Diesel related threads and would like to meet you if our leave schedule matches as my brother stays in Karachi and sometimes I visit karachi. Thanks a lot for your great and detailed help.

Hi Zulfiqar,
I bought this 2002 diesel car of Toyota corolla with 2.0D engine.
my car give 8kms per litre and car pickup is bad the engine shuts off if car speed is 20km and I try to pull in second gear. I live in quetta and uneducated, hit n try mechanics are all around us. Please guide me what need to be done in my cars engine and who is good for this job
thanks,
Malik

diesel pump need adjustment

[noumanzia]

Sorry I didnt get your question.

I have Toyata Corolla 2.0 D , Model 2003-4.
i have few questions. it has some sort of black smoke while starting in cold state.
Some one said me that it needs complete overhauling, which cost about 50 K.
Now the questions are
should i replace it with petrol engine and install CNG?
If i overhaul it, what u suggest, what thing should be done?
what parts should be replaced?
also tell me about some good diesel lab for all sort of testing , like fuel pump, nozzels?
Thanks

[th3_f1]

thanks I have noted down your advice but let me hear from Mr.Xulfiqar that who can check all these things in Lahore or if he himself can do this job I will consult him, engine is weak but not at that stage,no smoke good torque the max speed on meter is 200km/hr but I can achieve upto 145km/hr or 150km/hr as the engine is 12 years old.

What u sure u can achieve upto 150Km/hr???? o:o
I really doubt that bcoz my 2007 model 2.0D Saloon's top speed is 110-120Km/hr MAX!!!

[th3_f1]

Condition of my car engine is also 8/10 and odo meter reading 100K km's...

read my signature line - gather data & post here again. have some patience and follow instructions from Xulfiqar for corrective measure. For heaven's sake have heart do not act stupid by replacing a diesel Bull with a CNG monkey
