4G15 Cylinder Head Gasket

Mitsubishi 4G15 engine is very popular in Malaysia due to the Proton Saga megavalve and Proton Wira 1.3 and 1.5, the original material for this type of cylinder head gasket is normally Asbestos type and after that is Graphite after the asbestos material is ban.

Due to there are a lot of people modified the engine with Turbo spec install into it, the normal material of cylinder head gasket can not stand for this kind of high temperature and pressure.

After that, there are people trying to use metal type of gasket which they try copper and aluminium as well, but this 2 type of metal can't meet the requirement.

Finally they need to use the material which the metal type is use for the 4G6series and 4G9series of engine.

Mitsubishi 4G61-T VR4 1600CC

Nowadays there are a lot of Mitsubishi EVO fans like to install the 4G63 Turbo type of engine for their vehicles, mostly using the metal type of cylinder head gasket.

Before the 4G63 type of engine, the new generation may not aware there are evolution from Mitsubishi very first 4G61 in the year of 1987 to 1990, where by the engine capacity is only 1595cc, and the material of the cylinder head gasket is still using the graphite (carbon) type.

Other improvement you can notice is the exhaust manifold gasket which in the early day their material is using the powerbestos type and the current material already using the multi layer steel product.

Simple knowledge on Waterpump

We found there are some habit from foreman or end consumer when they go to the parts shop to buy the waterpump assembly for their car.

Once the shop give them the waterpump they wanted, first, of course they will open up the box and check the condition on the waterpump, that is normal.

Secondly, they will start to turn the waterpump fan on the pulley side of the waterpump to check if the fan are moving smoothly, we can say that nearly 100% will do this kind of action, and most of us may think it is all right to do this.

For your info, there are mechanical seal install inside the waterpump where the area of the waterpump fan is turning. This type of mechanical seal is to prevent the leakage of water in that area, and don't be surprise that it work more effective when it had water inside.

By turning the waterpump fan without any water as medium in it, will scratch the mechanical seal of the waterpump, hence damage the surface of the mechanical seal which will cause it life span more shorter and leakage will occur sooner than it normal will be.

K3-VE and 2SZ-FE Cylinder Head Gasket

Daihatsu K3-VE engine and Toyota 2SZ-FE engine is very similar, there are 3 type of model which using this engine in Malaysia market, which is Perodua Kembara DVVT, Toyota Avanza 1.3 and Perodua Myvi 1.3.

Since the O.E.M. type of cylinder head gasket for this type of engine is very thin, many of the maintenance personnel is having a problem to effectively seal the oil passages through the engine block. Hence they try to use the Graphite or Silicone type of gasket instead of their original design is metal type of gasket.

So what is the actual problem cause of this kind of sealing problem, as some had commented that the O.E.M. type of gasket, there are additional combustion ring that sitting near the round shape of piston area, which actually made the area become 3 layer instead of 1 layer at other place of the gasket.
