Toyota FJ Cruiser Cylinder Head Gasket

Toyota FJ Cruiser (GSJ10/15) in install with 1GR-FE engine, unlike other GR series of engine, which is consider more popular, like for 4GR-FE in Toyota Mark X and 2GR-FE in Toyota Vellfire, the 3,956cc 1GR-FE engine most probably is seen in Toyota FJ Cruiser only in Malaysia market, although there are others Toyota model that using 1GR-FE engine which you can have a look here, 

Interestingly, both 1GR-FE and 2GR-FE have the same bore diameter of 94mm, which their different is the stroke for 1GR-FE is 95mm and 2GR-FE is 83mm, but their head gasket have different part number, they looks very similar, and may need put 2 gasket side by side to check on their differences.  
 

Toyota Nadia Vista Intake Manifold Gasket

Toyota Nadia SXN10 model under engine code 3S-FSE have a very unique intake manifold design if compare to the other Toyota 3S series of engine, it have gasket #1 and #2 as shown in above diagram, this 3S-FSE engine also can be found in Toyota Vista and Toyota Vista Ardeo SV50 model.

 

Toyota Vios NCP and Haval H2 Rocker Cover Gasket

China made Haval H1 is known to be using the Toyota 1NZ-FE as their engine, which is also use in Toyota NCP series model, their engine gasket parts are actually same for each other. And now is the interesting thing to found in the new Haval H2 engine, overall, it can be said it is a minor modified for the 1NZ-FE engine, most of the gasket is still interchangeable between the old and new version.

But look at the above photo which is the rocker cover gasket for Haval H2, you will find that the original design which the plug seal is attached to the rocker cover gasket (refer to the bottom photo on the Toyota Vios NCP series rocker cover gasket design), the Haval H2 design it as such the plug seal is separate in 2 pieces from the rocker cover gasket.

It is unknown that if the old type rocker cover gasket can be install on the Haval H2 or not, other notable change in the engine gasket is the intake manifold gasket, the old version of intake manifold gasket is using rubber o-ring type while Haval H2 intake manifold gasket is metal sheet type of gasket.

 

Nissan Juke 1.5 F15 Rocker Cover Gasket

Although Nissan Juke 1.5 F15 engine code is also HR15DE, but the rocker cover gasket is not same as the first batch of HR15DE engine which use in Nissan Almera and those HR16DE engine which use in Nissan Latio 1.6 and Grand Livina 1.6.

On the rocker cover gasket design, actually it looks similar to the first batch under OEM part number 13270-ED000, this piece with OEM part number 13270-1KT0A as shown in this post photo, have 2 piece small rubber lesser than the old version at its side of the rocker cover gasket.
 

Nissan Navara NP300 Intake Manifold Gasket

The Nissan Navara NP300 model, although still using the same engine code as YD25DDT which also found in their first Nissan Frontier and the previous Navara model, but their gasket kit have a lot of pieces having the new design, rocker cover gasket and exhaust manifold gasket is already not the same parts like previous model, but I feel their intake manifold gasket have the most eye catching changes if compare to previous YD25DDT engine, unlike their conventional style of making 4 ports of intake holes, this NP300 model design is more like those in Isuzu 4HF1 series of intake manifold design.

Mazda 2 ZJ engine Timing Cover O-Ring

The timing cover of this Mazda 2 and 3 under the ZJ engine code, have a very special o-ring at the timing cover which we mark at the above timing cover photo, and we can't find this o-ring is included in the overhaul set gasket kit. Since it is not in the engine overhaul gasket kit set, it may be include in their timing chain kit set but I'm not sure if it is or their timing chain replacement is done by purchasing all individual items.

Anyway, Mazda did service this o-ring for replacement in case the car owner just need to replaced that o-ring, under OEM part number ZJ01-10-673B,  you may find this o-ring design quite interesting in the photo below.

 

Nissan GTR R35 Plug Seal

Nissan GTR R35 VQ38HR engine rocker cover have 3 spark plug holes each side on the rocker cover as like the one in red circle in above photo, but one may notice the plug seal is not a service part under Nissan genuine parts option, although you may change to rocker cover gasket, it may be headache if the oil leak is from spark plug holes area.

In the one GTR forum, we found that some of the GTR owner had found out that one Subaru model crankshaft oil seal size is just fir nicely for the R35 plug seal purpose.

Although the oil seal price may cost higher when it compare to those VQ20DE and VQ30DE plug seal, which is under Nissan service parts, it still worth it if compare to change a whole new rocker cover.
