Bulletin: BMW N47 Head Gasket Differences

Models Affected: BMW 118D, 120D, 123D, 220D, 318D, 320D, 420D, 520D, X1, X3, X5

Engines: N47D20C, N47D20A-B, N47D20D

Years: 2007 – 2017

The team here at Southside Cylinder Heads have come across a variation between head gaskets on the BMW N47 Diesel Engines.  Both head gaskets look nearly identical however they are not interchangeable and using the wrong gasket will result in oil being pushed into the cooling system.

The information in regards to which gasket suits which exact model is confusing and difficult to decipher, so the best advice we can give is check very carefully against your old head gasket before fitting the new one.  Below is some pictures to help pinpoint where to look for the differences between the two.  It is the area in the middle that causes the problems, there is an oil feed that is blocked on one gasket (bottom picture) and the other gasket doesn’t have this extra piece on the edge to block the feed, and also has a different position for the water jacket holes in that area.

So far the problem has been identified in the N47D20C engine series, however we would also advise caution when dealing with the N47D20A-B and N47d20D engines.  If you need any further information call Southside Cylinder Heads on (07) 33435899.  The cylinder head and engine reconditioning experts servicing Brisbane and Australia wide.

 

Toyota And Subaru Valve Spring Recall

Australian Subaru and Toyota dealerships have sent out a recall on valve springs in Toyota 86 and Subaru Impreza, XV, Forester and BRZ. This effects 5,407 Toyota 86 vehicles produced from April 2012 to July 2013.

The Subaru recalls affect over 24,000 cars including Impreza models from year 2012-2013, as well as XV and Forester vehicles fitted with a 2.0-litre engine (manufactured January 16, 2012, to May 14, 2013). The issue also affects BRZ vehicles – manufactured from start of production to May 14, 2013.

High stress and sub standard material quality appears to be the likely cause, and may lead to fracture or breakage of the spring and cause power lose to your car and cause further damage. Southside Cylinder Heads advise taking your vehicle back to the dealership for a warranty repair to rectify problem.

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.

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 🙂

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

EGR Cooler setup Nissan YD25

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.
