Bulletin – Suzuki Grand Vitara cracking issues

Models Affected – Grand Vitara JB 2008 – 2009 (2.4l J24B Engine)

Fault – Crack in top of cylinder head, water mixing with engine oil

Symptoms – Milky colour oil, loss of coolant with no external leaks present, water contamination in engine oil.

The first run of J24B engines suffer from cracking in the top of the cylinder head.  The crack occurs from one of the three casting bungs that screw into the top of the head (under the rocker cover, between the camshafts), and the crack will normally run to the nearest head bolt hole.

The symptoms mentioned above may be present along with engine overheating or possible internal engine noise. The crack allows coolant into the top of the cylinder head and mixes with the engine oil, it will look like a caramel milkshake!  A tell-tale sign will be if the engine oil is overfull and the radiator is down on water, most likely that water has made its way into the sump.

– See the technical bulletin here Suzuki USA Technical Release –

Suzuki USA has acknowledged the fault and are repairing vehicles under an extended warranty scheme, however to date as far as we are aware, Suzuki Australia hasn’t acknowledged the issue and are not covering any repairs.

To add to the issue, the engine blocks are also known to crack without warning and without overheating.  Steer clear of the early version of these engines. If you are considering buying one, make sure the build date is 2010 or later.

Volkswagen Turbo Diesel Camshaft Issues!!

Models Affected:

 – Volkswagen Transporter T5 2004 – 2010 2.5 TD
 – Volkswagen Transporter T5 TDI 2004 – 2010 2.5 TD

Volkswagen Transporter 5 cylinder turbo diesels are having issues with the valve train.  Hydraulic lifters, camshafts and camshaft bearings are wearing out prematurely resulting in excessive noise from the engine.  The exact cause of he failure is still yet to be pinpointed but poor lubrication to the top end is likely to be playing a major part.

 

 

 

 

 

 

 

As shown in these pictures the damage can be quite severe and left unchecked will continue to damage surrounding components and engine failure will be inevitable.

 

 

 

 

 

 

 

 

If caught early you can rectify the issue by simply replacing the camshaft, all hydraulic lifters and camshaft bearings.  However if the damage has extended to the valves then the cylinder head will need to be removed for repairs also.  Southside Cylinder Heads have SST timing kit required carry out these kind of repairs on your Volkswagen.  Give us a call anytime and we can look after you 🙂

See our online store for replacement camshaft kits

 

 

 

Nissan YD25 EGR Cooler Issues

Problem:

EGR Cooler corroded or split and leaking Coolant

Vehicles Effected:

Nissan Navara D22 & D40 with YD25DDTI 2.5 Turbo Diesel Engine

Nissan Pathfinder R51 with YD25DDTI 2.5 Turbo Diesel Engine

EGR Cooler

We are seeing more & more problems with the EGR coolers in the YD25 Nissan engine.  The coolers tend to corrode or split resulting in loss of coolant and due to the high temperature of the exhaust/EGR system the coolant loss often goes undetected as the coolant evaporates and doesn’t leave a puddle on the ground.  If the problem goes unchecked the cooling system will run dry and the engine may overheat and require major repairs.

To fix the issue some people elect to bypass the EGR system completely using blanking plates on both the exhaust and inlet manifold & disconnecting the coolant flow to the EGR cooler.  From all reports this has been an effective fix but Southside Cyl Heads doesn’t recommend this because removing the EGR will alter the vehicle’s emissions levels & render the vehicle unroadworthy

EGR Cooler Faults

We recommend simply checking your coolant levels regularly and if you notice a drop in the level, get the cooling system checked and check for stains around the EGR pipe ancooler area.

Catching the problem early and rectifying the issue could save you thousands in cylinder head repairs in the event of the engine overheating.  If you suspect your EGR cooler could be leaking, give us a call and we check over the system and put your mind at ease.
