More metal per $$$

LoL

I think it actually made the ride better. Japanese cars have this wobbly feeling whenever another vehicle zoom past by. Koreans are slightly better at this and also sound proofing.

well here's the thing. ppl exp is very bad statistic for your own information. normally they wanted to defend their brand and purchase decision thus did not tell the full story. i myself is in automotive business, i got my source of info based on statistic from mechanic, and spare part dealers, not end user who tend to be bias.

As i said earlier, besides fuel consumption, i never had any mechanical drivetrain failure with my koreans. yes nitty bitty noise does came out but it can be solve easily. reliability wise, it was consumed with nationwide perception that korean would be inferior and it has been ingrained in their mind that it is true whereas most of the people who agreed dont even own a korean.

btw the city civic is just a quick typo. no need to raise the issue at all. u know what i meant

When you do not change the engine oil, basically those special chemicals in the engine oil that resists heat, does cleaning, lubricating are all degraded or gone. No different to having cooking oil inside.

Modern engines are bad in this department. They are manufactured at high material tolerances that a little deviation can cause failure. For them its accuracy . For everyone means you have to follow service schedule. Else when it fails it will fail.

Cannot think the old way where little failure in engine will result in engine replacement. Almost no company uses cast iron for engine anymore. Everyone is aluminium. Lighter, but prone to fracture than iron.

The point is, the damage is not caused by mechanical failure or defect. It is caused by degraded engine oil that caused the engine not to lube properly and heat killed everything from pistons, cylinder walls, gaskets & warped the head.

It was not caused by degraded engine oil. Semi-synthetic engine oil can last 10,000km or 1 year easily and this may not even be its limit. As the mileage wasn't reached the oil was changed at 1 year.

I have a theory, of course could be completely wrong.

Do you know how when you boil water, there's a lot of bubbles, that is from dissolved gases in the water.
I think the same is happening maybe.

no this was not caused by engine oil. confirmed by hyundai sa. otherwise you will see more uniform damages across the engine instead of just 1 particular part. the piston ring, piston, conrod and others were deemed to be in good condition by SA.

no boiled water will bubbling and burst like in my video hahaha.

Also was there coolant used in the first place? I doubt the car never came with coolant. And you know coolant raises the water boiling temp so bubbles will not form. If you use just water, those bubbles will accumulate air inside the system. And air is proven not to be a good heat transfer medium than water.

Woobly or not can be done by suspension tuning....but have to agree that koreans do have better sound proofing.

+1

Only after really owning it that a driver can appreciate the difference of a korean car compared to japanese peers. It's not to say that japanese car sucks per se, but the value proposition and reliability image is much overstated.

Korean cars get a bad rep due to the low volumes and any breakdown seems to "feel" exponential compared to japanese peers.

Here's the crux, the failure is not caused by overlooked oil change. But the engine oil does have a role to play in this failure.

Actually, engine oil's greatest enemy is heat. With the coolant drying off, the heat inside is crankcase is pretty horrendous as it will be the engine oil that is doing the primary job of cooling instead of the coolant. The additives and the oil chain could have broken down pretty badly. Try heating your cooking oil at high heat for 15 or more minutes and see how it smokes and degrades.


Main purpose of coolant is antifreeze properties, rust/corrosion protection, a little bit of water circulation lubrication and some form of defoaming agent (prevent cavitation, almost like sand blast effect but caused by air bubbles bursting). The 1st 2 plays the greatest role. The cooling circuit can run with straight water and the cooling properties are actually better as the coolant actually has lower specific heat (heat carrying capacity).

Secondly, when the cooling circuit is under pressure, the boiling point actually increases.

i already answered as to why the water look clear.
it got to do with testing the system for leakage before pouring expensive coolant and waste it unnescessarily

I beg to differ.
Engine oil degradation ?
This engine overheating has no relations with engine oil .... or its degradation.

oh not sure if it helps but fyi, i use Pennzoil Velocity 5W30 Engine oil. Fully synthetic

Did the overtemperature warning light indicate the alarm?

If void warranty, TS cannot claim already. Korean car spare parts are expensive in Malaysia....

not really. if compare ori and new, the price comparable wit japs.
if 3rd party then yes, jap cheaper
