End of story....we are still waiting.

Good day our Oga/doctor @ GAZZUZZ...i learn I lot from you thanks for the good work God continue to bless you... Please sir.. Mean it's good to you coolant inside can than water right? Do we use it only or mix with water? Also what coolant can I use for corolla 2007 and how much? Did you have for sell?

Thanks in advance

GAZZUZZ:


6-7quartz of this and you should be ok. 14k for this gallon.

radautoworks:


Heh, heh. Finally something I'm cheaper than you on lol. Tell Uncle Yusuf to come back with his English speaking nephew!

GAZZUZZ:


With the combination of abuse, vehicle still carried on for a long time, (testament to toyota builds) the the engine must have developed a sludge buildup, but did not cause an immediate threat because the sludge was sticking to the walls of the engine and other parts, it was not hanging loose, the coolant passages had already started corroding, but did not show any signs of leaks because there was no pressure on the coolant system (In effect the water was sort of sitting in a bucket but the holes where on the cover of the bucket)

The engine was also very in-efficient, and burnt up more fuel.

the reason for the added fuel consumption is centered around ECU programing.

Every car once started in the cold position will receive instructions for higher Rev, and longer pulses to the injectors to enable the engine warm up real quick, this is necessary especially in sub-zero conditions to ensure engine does not stall.

The first 10-15mins of a cold start should be enough to raise the temp of the coolant from -x to between 90-104degrees celcius.

After this the engines rpm will return back to about 700-800RPM and pulses to injector normalize.

Now in the case of this engine, the temp never rose to 90-96deg, infact for a better part of its life, it was stuck at around 65deg celcius. The effect of this is the engine ecu will continue over fueling and keep the RPM higher than usual levels.

To combat this behaviour the roadside tech would have tried Bringing down the RPM manually by blocking off the IACV with a Foreign material to ensure he gets a desired rpm set manually from the butterfly. in doing a manual rpm set, the rpm would be unable to adjust automatically to expected load e.g the a/c next would be a wave of vibrations when ever the a/c is engaged or when the headlamps are set to full beam, or when the steering is turned at any angle.

Trust the road side Mech, he always has a way to counter 1 abuse with another, they incorporate an electronic valve and wire it to the compressor signal, and the vacuum side to the intake, the smart ones connect the air inlet side to the intake air hose before the airflow meter to reduce the hissing sound and avoid a lean mix code, the not so smart ones leave it open.

A combination of all this abuse is Recived by the catalytic converter, it receives Nigerias adulterated bad fuel a rich mixture, black sooth and ultimately gets blocked.

Well again the roadside has a solution to this again there's the smart one, and the outright foo.l. The smart one takes out the blocked catalyst and sells, the foolish one takes out the old catalyst, Sells and installs a wire mesh to avoid the hollow sound. Reminds me of ogyrt who has advertised every abuse I just mentioned here as a way of fixing a car

The effects of overfueling also cause what is called bore wash, which is when fuel from the injectors mixes with engine oil intended to lubricate the cylinder walls and causes poor lubrication and thereby causing rapid wear of rings pistons and Cylinder walls.

long term engine was on a collision course with death.

Mayor is done, Hybrid coolant now in the system, he thanks his Lastma buddies, takes a turn on bariga bridge, and fires back to sangotedo........


The bridge was free of traffic, and they had a long way ahead, Uncle re-initiates formula 1 skills while passing a nissan almera driven by nurey @ 160km/hr....


Nurey gives chase.... Towards the end of the bridge, there is white smoke coming out the tail pipe of nurey's almera, and he has to park.

uncle Grins like Elshanautos, and tells him self "I still got it

I cant remember how I found myself in this thread and got hook with the interesting story. But good I did.

this is a typical example of why you should not pour full synthetic oil into an engine that has been abused.

Uncle places a call to his buddy cosplay.

uncle: ore mi, ah I need your help. He narrates his ordeal to his friend.

Cosplay: Hand over the phone to the most senior officer at the place and let me speak to them.

Uncle: ok ore mi, thank you.


Cosplay and ipfreely talk for about 5min, and after a while ipfreely starts laughing and cracking jokes over the phone

Uncle is now thinking of his 500 naira card but there's nothing he can do. They continue Their Gist until credit runs out, mopol signals Banky3w to let them go with a warning, while he Flags down another Vehicle, a green Volvo without Number plates driven by valarinz. Banky3w smiles mopol smiles as Uncle takes off.

The drive Home was uneventful, and They Get home really exhausted.

Madam Uzuz brings in dinner while they all eat while narrating the events of the day.

this is a typical example of why you should not pour full synthetic oil into an engine that has been abused.

remember we talked about how sludge gradually builds up in the engine, well sludge if left alone, does not cause any immediate harm,in most cases engine death is slow but sure.

Now this is what happens when you pour synthetic oil into an engine with a great amount of sludge.

Full synthetic engine oils have cleaning additives, they work like detergents, and are able to break down accumulated sludge in the engine very quickly. The ability of full synthetic oils to keep an engine clean, in a healthy engine is harmless, the particles get trapped in the oil filter and after an oil (oil and filter change) drain the process is repeated again. sadly in an abused engine it is not the same. You have rapid breakdown of sludge, it overwhelms the oil filter, clogs up the strainer at the pickup screen of the oil pump, on and no time the engine is running on low oil pressure (which explains why the oil light started flickering in traffic) ultimately from low oil pressure the engine gets starved of lubrication, becomes noisy, rattles and finally freezes up.

full synthetic oil should never be used on an engine with long term abuse. Regular and shorter oil changes with mineral oil after returning temperature settings will be a better approach, to maintaining an abused engine, if you are not ready for a replacement or a rebuild.


As to what killed the honda V6 engine.

That particular model has a very sensitive catalytic converter system. In most toyota's, with age and mileage the catalytic converter gets burnt out, but in Honda, with age mileage and abuse the converter gets blocked, a blocked converter means exhaust fumes on that particular bank do not get to leave the exhaust system with ease, the exhaust system is narrowed down to a smaller diameter, a typical example would be drinking water from a cup VS sipping water from a straw.
The effect of a blocked catalytic converter results in overburdened connecting rods, excessive heat in Cylinder head, excessive wear to valve stem seals, and a general loss of power.

It is typical to find such cars smoking excessively (white/blue smoke).

Continuous Use of engine in that state leads to a catastrophic end for said engine.

With this last post I have finally ended this story.
I trust it was beneficial to many, and I hope you are not learning the hard way.

kcbaba007:
Sir, Gazzuzz, you are a blessing indeed, I appreciate other experienced car techs in the house, pls, could u give us some examples of mineral lubrication oils that will be effective as per cars?
e.g, I use a Honda accord 2005 model, I am.presently bringing it back to factory order, but skeptical about the lubrication oil to use, something within was actually telling me not to use d manufacturer's recommended oil

Second question sir, what if the oil strainer is cleaned out and sludge removed from the engine, will it be able to accommodate d manufacturer's recommended lubricating oil?

Third question sir, forgive me of my inquisitive nature, will it be wise to flush d engine to get rid of sludge?

Gazzuzz no story this year?

Toyota Super Long Life Coolant is excellent for newer model Toyota cars manufactured from 2004, but I discovered this OEM concentrate which meets the specs and costs a bit less. The premixed Toyota coolant costs about 11k in my area but this one is a concentrate requiring mixing with an equal volume of distilled water, so yields 8Litres and costs 8K
