Do you need a Hyundai iLoad specialist mechanic who knows the common iLoad engine faults inside and out?
All these problems can be avoided with proper maintenance!
Expensive engine faults have plagued the D4CB engine for many years. Time and time again we see situations where a mechanic will fix the obvious fault without finding and fixing the underlying cause of the issue.
Replacing a blown turbocharger or broken timing chain, without repairing the fault that caused the turbo to let go will get you back on the road for now. Unfortunately, you will soon find yourself back in the same position with your van on the back of a tow truck when another turbo charger bites the dust!
The D4CB engine (2.5L turbo diesel) in the Hyundai iLoad has one major flaw. After many years of faithful service, the diesel injector seat washers begin to leak. It happens gradually, bet gets worse and worse as the km’s rack up. Eventually the seat washers blow out completely. The situation you are left with is that a large amount of your combustion gasses, pressure and unburnt diesel (soot) ends up leaking past the washer and into the crankcase.
At this time, many mechanics will mistakenly tell you that your engine has excessive blowby and needs a re-build, but that is usually not the case. When the injector seat washers leak, the exhaust gas and soot mixes with the engine oil and forms hard lumps of carbon that go down to the sump and build up to eventually restrict the oil pickup. With reduced flow comes a reduction in oil pressure. This reduces lubrication to the turbocharger and timing chains. It also reduces the effectiveness of the timing chain tensioners.
This is the BAD NEWS!
These problems are mostly avoidable by following these 2 rules:
1) Replace injector seat washers every 100,000km
Every 100k we recommend the following…
2) Change your oil more regularly and don’t skimp on the quality!!
We recommend 10,000km service intervals as an absolute maximum and insist on a fully synthetic engine oil. This will keep your crankcase cleaner and will lubricate all those fine moving parts so much better.
When we inspect the injector washers in step 1 it is super important to make sure they weren’t leaking, if they were, there are a few more steps we need to take!
If the injector seats or injector washers are damaged and have leaked, it is essential to remove the engine sump and check the oil pickup for debris and blockage. In most cases, we will replace it completely if there are any particles stuck in there. Better safe than sorry!
