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.

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.
