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 Suzuki Technical Bulletin Release Here Suzuki USA –

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.

New Rugo 100 guide honing machine!!

 

New RUGO 100 Honing Machine

 

We are pleased to welcome our newest upgrade to our ever expanding workshop, the spanish built Rugo 100 valve guide hone.  Capable of honing a wide range of valve guides from motorbikes to small trucks,  as well as small end bushes, this machine gives a uniform, friction-less finish far superior to what can be achieved with old style hand reamers.

With the ever increasing use of bronze and brass in valve guides, valve guide clearance is more critical than ever before, and incorrect clearance can result in valve seizure in the cylinder head as well as premature wear in the guides.  Southside Cylinder heads strives to stay at the forefront of technological advances in the industry, so we can better serve our customers now and into the future.

 

 

 

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 🙂

New Ultrasonic Cleaning Technology

Over the Christmas break we were spoilt here at Southside Cylinder Heads as we too received Christmas presents! We were lucky enough to get a BRAND NEW ULTRASONIC CLEANING MACHINE!

This machine has enough power to clean even the most stubborn Carbon build ups on Diesel and Petrol Cylinder heads/Blocks/Rocker gears and Timing cases.  Especially handy for late model turbo diesel inlet manifolds, which tend to become heavily carboned up and nearly totally blocked  resulting in loss in power and increased fuel consumption.  Dont forget we have a pick and delivery service available 🙂

All About Cylinder Head Hardness

With the advancement in engine technology more components than ever before are being manufactured out of aluminium.  The 70’s and 80’s seen the introduction of aluminium cylinder heads into mainstream family cars and now almost all new engines use aluminium heads and in many cases an aluminium engine block as well.

Digital Hardness Tester

Although both strong and light, aluminium is also a relatively soft metal that needs to be alloyed with another metal in order to have enough hardness to be used in an engine.  Typical alloying compounds are silicon manganese, copper manganese and iron.

When we talk about cylinder head hardness it is basically the ability of the component to resist being permanently deformed when a load is applied. Testing the hardness of your cylinder head is a vital part of the reconditioning process and the most widely used hardness test in the automotive field is Brinell Scale.

Depending on the manufacturing process and alloying metals used, cylinder heads will have different hardness levels from new, so for instance a new Mazda 6 cylinder head may be 125hb but a Toyota Corolla head may be only 110hb.  You would expect a new cylinder head to be in the vicinity of 100-130hb.

The only accurate way to test your cylinder head hardness is with a calibrated digital tester.  Our testing is conducted in 3 spots on the gasket face of each cylinder head and the average result is recorded.  Industry standard minimum hardness is 65hb and any heads with a reading below this level are unsuitable for reconditioning and must be replaced.  Unfortunately many workshops still use the outdated and unreliable manual “ball tester” that relies on a ball bearing in a tube to bounce above a line.  This type of tester is relatively cheap but has proven to be inaccurate in determining a cylinder heads suitability for reconditioning.

What causes the hardness level to deteriorate?

The single biggest factor that effects your cylinder head hardness is excessive heat.  Most modern engines operate at a temperature of approximately 88°c – 105°c.  When your engine overheats and exceeds its normal operating range, the increased heat puts major stresses on the aluminium cylinder head and starts to deteriorate the hardness value of the head.

Once the temperature of the aluminium reaches about 200°c – 250°c permanent softening of the alloy begins and the hotter and longer your engine is exposed to these conditions the more damage is done.  To minimise the damaging effects of overheating be sure to switch off your engine at the first signs of overheating and have your vehicle checked.

What will happen if I use a soft head?

Using a cylinder head that is soft (tested at 65hb or less) greatly increases the likelihood of premature head gasket failure as it has lost its structural integrity and ability to withstand load and stresses that occur during engine operation.  As well as gasket failure a soft head may also be more susceptible to warping and cracking as the weakened component continues to be subjected to the high loads and stresses of the combustion engine.

A key sign to look out for is head bolt recess or indentation caused when the load applied by the head bolts is too great for the soft aluminium and the bolts will start to sink into the head. These bolts pulling through the aluminium will prevent the correct load being applied to the head gasket and failure will be imminent.

If you have overheated your engine and suspect the cylinder head hardness may be affected, or you just want to be on the safe side, bring your head in to us and we can do a hardness test while you wait (in most cases), and best of all its free!
