The perfect design of some flywheel oil seal which the oil seal is come with the steel housing, due to the price of this kind of oil seal is higher than the normal oil seal, it normally not included in the overhaul set gasket.
Picture showed the flywheel oil seal for Nissan VQ series engine model vehicle which currently have Cefiro, Teana, Murano and Elgrand in their list.
The other model which have the similar oil seal is Daihatsu JB-DET engine which is modified into Kancil model in Malaysia which they usually call it L5 or L9.

Apart from the engine gasket, there are some important gasket for those engine which have the turbo charger install on it.
For example, the Mitsubishi EVO type of engine, which mainly comprise from 4G63 engine type, have their own Turbo Charger gasket as shown on the picture.
As the place which needed to install this type of gasket, their temperature and pressure is extremely diffrent in the place like at the engine side, hence, if one is using ordinary gasket material to mede this type of gasket, you may see the gasket may totally burn away after one round of runnng the car.
This is the beuty of the Japan technologies as the art of making this gasket is hardly able to follow from others.

Start from Proton Tiara, which at that time Mitsubishi still one of the shareholder of Proton, they had put in Peugeot TU1 engine on this model, but Proton Tiara seem is one of the failure vehicle in Proton.
Than they come with a replacement for Proton Tiara which they name it as Proton Savvy, this time they use the Renault D4F engine.
And some may notice that there are one series of Proton Waja 1.8 which also using Renault engine, with this kind of continental type of engine, their parts had become not cheap when compare to the Japan type of engine, for example, the overhaul set gasket for Waja 1.8 may cost near to RM600 when you buy it from Proton parts centre.

The type of engine on this Daihatsu Copen is JB-DET which is 4 cylinder engine, this is a powerful engine for the small car as Daihatsu normally design 3 cylinder engine for their below 1000cc capacity vehicle range.
Due to this type of engine is imported from Japan, sometime it is quite hard to source for their engine parts, especially when JB-DET also come with 2 type of design, although there are same for their Cylinder Head, Valve Stem, Exhaust Manifold, there are 2 diffrenr type of Valve Cover and Intake Manifold.
To diffrentiate this 2 type of engine, most of the Malaysian will call the first type as Kancil L5 Turbo and the other type will be Kancil L9 Turbo.
But still some of them will confuse with L7 and L9 type of engine, and actually L7 Turbo engine actually is EJ-DE/EF-GS type of engine, which their design is similar to the Perodua Kenari/Kelisa engine, which their valve cover gasket is difficult to source in local market as well.

Some using traditional type of bolt and nut, but there are quite a number of the design is using valve cover bolt, (some may call it valve cover seal or valve cover bush).
The picture show the type of vlave cover bolt that use on Nissan Cefiro V6 engine, which is in the VQ series engine type. This may applicable for Nissan Teana, Murano and Elgrand.

It is known that in the early day, quite a number of Korean passenger car is using the Japan made engine, such as the old model of Hyundai Sonata use dffrent type of Mitsubishi 4G63 engine, Kia Sephia is using Mazda B6-D type of engine, and old model of Kia Sportage is using Mazda FE type of engine.
With the improving of automotive technologies in Korea, their research team start to design their own engine, but most of them still modified from the existing type of Japan engine, they might modified the Valve Cover design, or design in Intake and Exhaust area.
Please find the article below from http://www.paultan.org/ which introduce the newly launch Naza Rondo 7 seater SUV, which have some interesting point in their engine specification.
Naza Kia Sdn Bhd has launched the new Naza Citra II Rondo in Malaysia. The Naza Citra II Rondo is essentially the Kia Rondo which is the replacement model for Carens that the Naza Citra is based on. The Citra will continue to be sold as a budget 7-seater SUV, and the new Naza Citra II Rondo will be positioned between the Citra and the Ria, bringing Naza Kia's 7-seater offerings up to 3 models.
According to Naza Kia, the new Rondo is built on the D-segment new Kia Optima platform and also share the Optima's sweet new GEMA-based 2.0 liter DOHC CVVT engine producing 145 horsepower and 189Nm of torque, mated to a 4-speed automatic transmission with sequantial manual shifting. The GEMA engine is a joint project between Daimler Chrysler, Hyundai and Mitsubishi. The 4B11 in the Mitsubishi Lancer is also based on the GEMA family.

We may start to know the existing of Nissan VQ35DE engine after the Murano 3.5 V6 is entering Malaysia, but the earlier type of VQ35DE vehicle that already driving on Malaysia soil is the luxury van of Nissan Elgrand.
In Japan, there are also Terrano 3.5 that using VQ35DE engine, the other type vehicle may be Maxima.
Although the engine specification is all putting as VQ35DE, they may be have some slight modification on the Cylinder Head Gasket and Rocker Cover Gasket for diffrence vehicle, hence before buying any VQ35DE gasket set, it is better to check the exact part number for their Cylinder Head Gasket and Rocker Cover Gasket to prevent of wrong purchase.
Also don't be confuse of this type of engine with VQ35HR which mainly use on Nissan 350Z Fairlady sport car.

A version 2 model, applicable to exhaust side VTC.To meet modifications to inlet valve seat internal diameters and ports, two versions Spec-1, diameter 31 and Spec-2, diameter 32-was created.
Easy increase of compression ratio
Compared to a genuine VQ35 head, the combustion chambers of the genuine VQ30 are used as the base for casting a processing, providing the compact combustion chamber required by an NA engine. The volume has been greatly reduced. With the combustion chamber volume reduced from 56cc to 46cc, the compression ratio is increased without head milling (using a genuine piston, from 10.3 to 12.0). In addition, by changing the piston crown shape, a compression ratio of 13.5 is also possible.
Easy increase of intake port potential
While this head uses the dynamic valve system of the VQ30 engine, the intake port uses the high-potential port used in the VQ35. Spec-2 uses an intake valve seat diameter of 32 to modify the intake port inside R to realize performance that greatly exceeds that of a genuine VQ35 engine (please see the table at the VQ35 Intake Port performance comparison).
* The VQ35DE engine is a V6 engine using VTC. Do not use simple milling of the head to reduce combustion chamber volume.
Spec-1 secondary spec

Understanding why a relatively inexpensive head gasket costs so much to replace means first realizing what it sits between. In the engine block are pistons that travel up and down in cylinder bores. The pistons are connected to rods, which in turn are connected to a spinning crankshaft from which the vehicle takes its power. Bolted to the top of the engine is the cylinder head. Inside the cylinder head are valves that open and close to let air and fuel into the cylinders and expel the spent exhaust gas.
The head gasket is compressed between the engine block and the cylinder head. The head gasket seals in the internal combustion process and also keeps coolant and oil from mixing together as the two fluids travel from the engine block to the cylinder head. Head gaskets themselves are not very expensive. What ends up costing big money is getting to it. Removing and replacing the head gasket means undertaking the major operation of removing an engine's head.
A head gasket can fail for a number of reasons, none of them good. Engine overheating is the most popular culprit. The metal of the engine block and head expands beyond limits during overheating. This expansion can pinch the head gasket to the point where it will fail. The next major causes of head gasket failure are engine pre-ignition or detonation. The crux of these two conditions is out-of-time combustion occurring in the cylinders. Internal combustion is supposed to occur with both valves closed and with the piston at the top of its power stroke. Out of time combustion puts extra strain on the valves, pistons, and head gasket. Ironically, engine overheating can also increase the likelihood of pre-ignition and detonation. The sound of an engine pinging or knocking is the insidious sound of damage.
Head gasket replacement is not a job for the average do-it-yourselfer. While a head gasket expiring due to old age is rare, it usually means everything else is worn out to the point of replacement as well. Cracking the head off the engine and peering inside may reveal that everything else got fully cooked, too. The best way to prevent head gasket failure is to keep the cooling system in top working order and make sure the engine is in tune and running correctly. The failure of a $5 thermostat or $3 coolant hose can cause thousands of dollars in engine damage in a hurry. The following are a few general tips for replacing a head gasket. For vehicle specific head gasket replacement procedures always consult a service manual.
Step 1 - Getting down to the head gasket can be an involved process. Always mark and index everything before removal. In this case, it was easier to remove the exhaust manifold, head, and intake as a unit. A service manual is the first and most important tool in the toolbox.
