    Default Engine optimization Corolla 2.0D

    I am posting you 2 pictures. These were taken at higher resolution but have been scaled down by the website.

    Engine optimization Corolla 2.0D - amcolian1097 albums mycar picture6532 2


    https://www.pakwheels.com/forums/mem...ture6531-1.jpg



    In the first one you see 2 plungers one is that of CSD (the one in depth) and I wanted to know the function of the second one. Both were marked by me as plunger1 &2 but due to resizing the font is too small to read.

    In the second picture there is an adjustment screw which is lying loose and I want you to please tell me its function and what to do with it?

    Fiinally of course please tell me the the correct way to release the CSD.

    BTW my mechanic is far from competent. That is why I want that I should be aware of what needs to be done and how is that to be done. I will just ask him to do what I would learn from you.

    Thanks.

    <B><BIG>White smoke</BIG> occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include…<O></O></B>
    • Faulty or damaged injectors<O></O>
    • Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway).<O></O>
    • Low cylinder compression (eg caused by leaking or broken valves, piston ring sticking, cylinder and/or ring wear, or cylinder glaze)<O></O>
    When white smoke occurs at cold start, and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing.


    From above your problems seems to be incorrect timing set after pump and nozzle job,also one thing keep your Fuel tank full as with half or less level in the tank will cause condensation as this is cold weater so that moisture or water content will enter in combustion and will cause white smoke, also jerks as you feel. your nozzles might be leaking before the pressure limit those should pop.
    Let us wait for the Reply of Mr.Xulfiqar as me personally know the theoritical things but He has hands on experience.

    Thanks for the response.
    I have already read yours and almost all the threads related to Diesel engines and especially 2.0D engines.

    Specifically speaking I am not having any problems at all. There is no problem with the cold start or warm start, nor is there any with the consumption. After going through the threads I learnt that the cold start device should be working properly, so I tried to check it but could not move it so I wanted to know the proper way to check it. This measure is to ensure proper functioning of all the devices and parts just to avoid any future issues.
    Further guidance that I require is related to tappet adjustment on the following points:-
    1. How would I know that the engine requires tappet adjustment?
    2. What is the correct way of doing it?
    3. What are the adjustment shims called in the mechanic language? I mean what should I ask for if I require the shims?

    I uploaded the pictures and these are visible to me but everybody else says that these are not showing. I am unable to understand this phenomenon. can anyone guide me on this?

    Actually I have hot starting problem as I like to see a very quick start but I still have not seen it as I am outside country very soon I will check Cold start Advance plunger as Mr.Xulfiqar guided that on pump there are two coolant pipes connected,under that part plunger can be seen. I will update you guys about it.and regarding tappet adjustment do you just hear engine sound when it is cold and when it is hot,If you hear some beating noise as lifters are beating the valves because of clearence, Also if the car has mileage more than 100,000kms then we should get this done.

    I think both the signs you mentioned do exist in my case and my car would definitely require tappet adjustment. now I await guidance from experts especially from Mr. Xulfiqar.

    Still can not see the pictures, can you upload in the right format for example jpeg.

    Just for your reference pls. read this and make sure what you see from Exhaust of your 2.0D

    Black Smoke


    This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for :
    • Faulty injectors (injectors need attention at about 100.000 to 120 000 miles)
    • Faulty injector pump
    • Dirty air cleaner
    • Turbocharger or intercooler faulty
    • Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)
    White Smoke


    Normally means that the fuel injected into the cylinder is not burning correctly. The smoke will burn your eyes.
    • Engine/pump timing out
    • Fuel starvation to the pump causing the pumps timing not to operate correctly
    • Low engine compression
    • Water/petrol in the fuel
    Blue Smoke




    The engine is burning engine oil
    • Worn cylinders or piston rings
    • Faulty valves or valve stem seals
    • Engine over full with engine oil
    • Faulty injector pump/lift pump allowing engine oil to be mixed with the diesel
    we should be proud of safe driving.

    As such there is no issue of any black, white or blue smoke. Engine Compression is good. Not reducing oil. only this tappet adjustment might be required for which I seek the valuable guidance from experts.

    It is a general rule that every 100,000 kms tappets be adjusted for shim/bucket tappets like the 2C diesel has. It greatly helps in keeping fuel consumption good, easy starting and good engine torque.

    The smoke analysis is shown very good but the biggest problem with diesel engines is that they dont actually blow blue smoke when they consume oil, they actually completely burn the oil like fuel and the exhaust is black - the telltale sign is over oily exhaust and high oil consumption.

    Dear Xulfiqar Bhai, I have no idea about the 2C pump specifications and pressure and flow etc also have no idea about injector opening pressure, so If you remember pls., share us though If I do this I will consult Toyota diesel Lab and also I will ask that if they set the engine timing with dial gauge inserted in the pump.
    we should be proud of safe driving.

    You can ask a toyota dealership for a copy of the spec manual for the diesel injection system, its only one page long. Offer some money for it.

    If your diesel lab also installs the pump then they should use the dial gauge and make sure the CSD is operational and all injectors are balanced to an error of 5 bar between any two injectors.

    If they dont - look for another lab just use the lab for pump calibration and a proper shop to install the pump.

    I picked this picture from a nissan diesel forum to show you the placement and shape of the CSD on a Bosch VE type pump which is the pump used in many many diesel engines.

    This type of thermally activated bellcrank type cold start device is found on the Toyota 2C engine. On your 2C diesel it faces the front of the car.
