Nissan Skyline GT-R R35 is using the VR38DETT engine, this is the engine using in the GT-R from 2007 until present, this engine also use in the limited production Nissan Juke-R, Infiniti Q50 Eau Rouge Prototype.

This V6 engine consider have a similar design in their rocker cover like those in VQ series, there are 6 pieces plug seal on the rocker cover, 3 each in the left and right rocker cover.

Unlike the earlier VQ series where Nissan had the plug seal to service for the after market replacement, but for the VR38DETT Nissan only come out with the rocker cover gasket for replacement, they didn't actually produce the individual plug seal, but you can see the plug seal clearly in the new rocker cover in below photo.

Since there are customer looking for the plug seal with bringing the plug seal to check the size if any other oil seal can be use for replacement, we found out that one of the Subaru crankshaft oil seal is fit nicely and perfectly on the rocker cover plug holes. 

 

Mitsubishi 4N15 Cylinder Head Gasket

Mitsubishi 4N15 engine is a 2.4 MIVEC engine which can be seen in the Triton 2.4 or Pajero Sports 2.4 in Malaysia market, the details and history of this Mitsubishi 4N1series engine can be found in the Wikipedia link here.

Due to it is an all alloy engine with aluminium die cast block, the cylinder head gasket material may be crucial, and you may find the KP brand cylinder head gasket is exactly same as the Mitsubishi genuine parts which dismantled out from the engine.

Nissan Almera 1.0 Turbo Engine

Nissan Malaysia is launching the all new Almera model with 1.0 turbo engine, from the Nissan Malaysia official website, you may found that the 3 cylinder 1.0 turbo engine code is HR10DET, so is this HR10DET engine gasket will have any similar gasket with the previous HR series of engine.

Of course I don't have the gasket as this is consider a new engine from Nissan, from the Wikipedia introduce on HR series engine, the 3 cylinder engine is mainly on HR12DE and HR12DDR engine code, which is mainly found in Nissan March K13, Micra or Note model.

The photo below is the HR12DE engine gasket kit for a record, let see if we are able to have the HR10DET gasket photo to view as soon as in the year 2021, I'm quite excited to know how their turbocharger gasket looks like.

 

Mazda Bongo 2.2 Rocker Cover Gasket

Mazda RF and R2 engine is consider one of their trademark 2.2 diesel engine range, mostly the RF series of engine is using 1 piece of rocker cover gasket in one engine, interestingly we found this Mazda Bongo Brawny which also install with a 2.2 RF series engine, is using 2 pieces of rocker cover gasket.

And it uses 2 pieces rocker cover gasket is not like those rocker cover which design a such have 2 separate cover side by side, but there are actually separate in 2 different layer at the engine just like what you see in above diagram.

So it is curious why the rocker cover have to design as such need to use 2 pieces of gasket? Is it there are any special function for this engine under this design?

In the latest occasion, we found that this engine is use in Nissan Truck SKF2 model.

 

 

Chevrolet Sonic 1.4 Cylinder Head Gasket

This post is another sharing of cylinder head gasket design from USA which may have a bit different looks when compare to the conventional cylinder head gasket design for the Japan model.

This Chevrolet Sonic 1.4 cylinder head gasket, have a very long and extended part near to the timing chain passage area, and there are 2 holes in this gasket have a very unique, you may find it in the photo above at the bottom left of that gasket, another hole at the second bottom right of that gasket. 
 

Nissan X-Trail T31 Gasket Kit

 

Nissan X-Trail T31 model engine is basically the same family as the T30 model under the Nissan QR series of engine, the same engine code of QR25DE is use in both T30 and T31 model, with the some improvement made on the rocker cover and intake manifold.

Both model rocker cover gasket and intake manifold gasket can't be interchange, for the cylinder head gasket, although it is different OEM part number for both model, and you may found minor different in both cylinder head gasket design, but it seems it can be interchangeable use in both type of engine.  

Mitsubishi Minicab 3G83 Gasket Kit

Mitsubishi Minicab with 3G83 engine actually have the 6 valve and 12 valve version, today we get to look at the 12 valve version which customer already dismantle the top part of the engine.

Above photo is the rocker cover dismantled from the engine, the 3 pieces of plug seal use in this model actually is in use in quite a lot of model in Mitsubishi range.

The below photo you can see the 3G83 engine code stamp on it.

The original type of the exhaust manifold gasket you can see from the above photo is the type which have the wall to block the wind, while in most of the time the after market gasket kit is come with the flat type of exhaust manifold gasket, which you can find the gasket in the photo below.

 

Subaru FB20 Exhaust Pipe Gasket

In the Subaru F series (FA20 & FB20) engine, their exhaust manifold gasket is actually design same size as the EJ series (EJ20 & EJ25) engine, but in the exhaust pipe side, the gasket as shown in the photo for the F series, is slightly bigger compare to the EJ series type.

But when we looking at the FA20 (Subaru BRZ) gasket kit, this gasket didn't seems under the content of the gasket kit, but it can be found in the FB 20 for the Subaru WRX model gasket kit. Even the FB20 for the Subaru XV model don't have this piece in their gasket kit content.

 

Honda CRV 1.5 Turbocharger Gasket

 

We seldom come across with Honda turbocharger stuff previously, only when Honda Malaysia introduce the Honda CRV 1.5 Turbo few years ago, I'm starting to find out how will the turbocharger gasket looks like.

This CRV 1.5 turbocharger is also use in the Honda Civic 1.5 Turbo FC1/FK7 model, the turbocharger is looks like the above photo with the gasket in the photo is the items #18 and #19 in the below diagram, currently we have the #18 in stock which is show in the last photo which we believe it should be the main gasket to replace whenever the turbocharger is dismantle at that area.

Nissan 350Z Upper Plenum Gasket

 

Nissan Fairlady 350Z have a very unique design above the engine which it have a plenum design, the upper plenum gasket have total 18 screw holes, so how would you like to tighten the bolt in the correct sequence? 

An I found this tighten sequence from Z1Motorsports website which it may useful for those who try to install the new plenum gasket on their 350Z engine. 

Below are the photo of the plenum gasket, the plenum, and the plenum with the cover open up in the engine bay.

Nissan Navara NP300 Rocker Cover Gasket

Nissan Navara NP300 is using the Nissan YD25DDTi engine, which it seems same code as the previous Nissan Frontier model, but overall there are some modification improvement of the engine which made quite many gasket in the new model can not be interchange with the old model type of gasket.

Of course the first common gasket we noted the difference is the rocker cover gasket, as it is tend to be the first gasket part need to be change in the engine for most vehicle, as apart from the Nissan Navara NP300, the new Nissan Urvan NV350 is also using the same engine, may be it is time to study the whole gasket kit after we already made the rocker cover gasket available in invventories.

 

 

Nissan Juke 1.6 Gasket Kit

 

Nissan Juke 1.6 which is using the HR16DDT engine, have some interesting design made on the gasket, most may thought that HR16DDT should be in some kind of relation with the HR16DE engine, that's not wrong, with the cylinder head gasket is basically get a modification from the HR16DE type of cylinder head gasket.

But the rocker cover gasket, it is surprisingly using the MR18DE/MR20DE type of gasket, and the intake manifold gasket is also a bit modification from Nissan Serena C26 which is MR20 engine. The exhaust manifold gasket is with the heat insulation design, which is different from the flat exhaust manifold gasket design from HR16DE or MR18DE engine.

Ford Mustang 2.3 Full Set Gasket Kit

In the earlier post we show what is the design of the Ford Mustang 2.3 Rocker Cover Gasket, this post we share a photo of Ford Mustang 2.3 Full Set Gasket Kit.

The rocker cover gasket is pack in a plastic bag in the bottom left of the photo, so you may refer to the earlier post on the photo of rocker cover gasket.

As you can see, the cylinder head gasket also have the design looks alike those in Mazda LF, L3 and L5 engine and also those in the Ford Focus III, but still this gasket is design specific for the Mustang model which the gasket from other model can't interchange to this engine.

The gasket in the centre of the photo is the exhaust manifold gasket which also have different design from the conventional exhaust manifold gasket which normally have 4 exhaust holes for this 4 cylinder engine.

The flywheel oil seal looks like same with those Mazda LF, L3 and L5 model but it is still not sure for me now as I don't have this physical parts to compare it with the Mazda model. 
 

Ford Mustang 2.3 Rocker Cover Gasket

This Ford Mustang 2.3 Rocker Cover Gasket looks very much like those Ford Escape 2.3 or Mazda 6 with L5 engine type of gasket, the differences from this piece of rocker cover gasket is that it have 2 curve at one side of this gasket but the other version is flat all the way.

The centre par is same have 3 pieces of gasket which 2 pieces is a bit square and 1 piece is a bit rectangular in shape, but it have extra 2 piece of oil seal like gasket which the other version don't have it in the rocker cover design.

Nissan Serena C26 Intake Manifold Gasket

The Nissan Serena C26 is using the MR20DD engine, it seems their engine gasket should be roughly interchangeable with the MR18DE or MR20DE engine, but the manifold system in this MR20DD engine have little modification from the MR20DE type.

As the Nissan HR and MR series of engine, is design as such once you change the rocker cover gasket, you may need to change the intake manifold gasket as well, the MR20DE and MR20DD engine is sharing the same type of rocker cover gasket but not the intake manifold gasket.

The photo show the intake manifold gasket for Serena C26 model which carry the OEM part number 14035-1VA5B.

Honda Transmission Linear Solenoid Gasket

This piece of gasket which found in quite a number of Honda model in their transmission linear solenoid area, for the whole transmission there are 2 solenoid which another one using a bigger gasket, it may be not belong to the engine area, and is fall under transmission parts, since we are in the gasket field, sometime we also need to source some gasket at the transmission side for customer.

Is it really the rocker cover gasket for Toyota Vios?

This piece of rocker cover gasket is belong to the Toyota 1NZ-FE engine, which in Malaysia market mostly the first few generation of Vios NCP model are using, but this piece of rocker cover gasket is not really for Vios, the plug seal connection area with the rocker cover gasket, the traditional Vios rocker cover gasket is straight to the plug seal holes, and not like what you see in the photo have a U shape connection on it.

In the website, we can see some of the Toyota Corolla Fielder which having 1NZ-FXP engine on it is using this type of rocker cover gasket. Or there are one generation of Vios is Malaysia is using this type of rocker cover gasket before it change to the 2NR type of engine.

Honda CRV 1.5 Turbo Rocker Cover Gasket

Malaysia have their smallest CC Honda CRV with a 1.5 Turbo engine, this engine also found at those Honda Civic 1.5 Turbo version, the rocker cover gasket with Honda part number 12341-59B-013, they design a hole on the rocker cover gasket there, which should have some special purpose function on the rocker cover side, anyone know what is the purpose of having that hole?

Proton Campro CPS engine Valve Cover Seal

For the Proton Campro CPS engine, which can be found in Preve, Exora, Suprima model, which at the car bonnet will have the CPS emblem on it, their rocker cover gasket is different from those in first generation Proton GEN2 and those later Proton BLM, and their rocker cover tightening method will involve the rocker cover bolt like in the above photo.

You can find a washer like of bush in the bolt, which normally we call it valve cover seal or may be rocker cover bush, it is interesting to find that the size of this seal is actually same with those use in Nissan old VQ series of engine, like Cefiro, Maxima, Altima and Infiniti G20, I30 and Q45.

Although for Nissan V6 engine it may need total of 20 pieces of this seal for one engine, the Proton CPS engine only need 8 pieces of it in one engine.
   

Toyota 2JZ-GTE Exhaust Manifold Gasket

For the inline 6 cylinder engine, which the exhaust manifold gasket will also have the 6 main exhaust hole, some of their gasket may design as such to separate it to 2 pieces so that the gasket will be not too long, but normally they design it as such the 2 pieces of gasket are same.

But that isn't  the case for Toyota Supra 3.0 2JZ-GTE exhaust manifold gasket, the gasket is design as 2 pieces separately for one engine, but that 2 pieces are with different design.

Mitsubishi Triton Rocker Cover Gasket

Let's have a look on the 2 difference design of the rocker cover for the Mitsubishi Triton model which currently common on the road in Malaysia, the above photo showed the Mitsubishi 2.4 MIVEC 4N15 engine rocker cover which is consider a bit new in Malaysia, their rocker cover gasket is more straight forward which attached together with plug seal.

The photo below is the Mitsubishi 2.5 4D56T 16V engine, or some call it as KB4T engine, which when one time of rocker cover servicing, you may need to change a piece of rocker cover gasket, 4 pieces of plug seal, 4 pieces of nozzle seal, and a set of o-ring which consist of 3 pieces same design of o-ring and 1 piece o-ring which is different from others. So should consider this rocker cover design in quite complicated manner.

Subaru IHI RHF4 Turbocharger Gasket

This 2 pieces of gasket is use on Subaru IHI RHF4 turbocharger gasket should be found on those Subaru EJ20 series engine model, but it is quite common to found some Daihatsu K3-VET and JB-DET owner is modified their turbocharger to this Subaru type of turbocharger.
