Mitsubishi EVO Cylinder Head Gasket

Talking about Mitsubishi EVO series engine, its predecessor should be the 4G63 VR4 type of engine, but for the VR4 model, their cylinder head gasket material originally is just using graphite, as the engine need to coupe with the more powerful turbo pressure demand, the EVO series had modified the gasket material to metal type.

The requirement for the cylinder head gasket not just stop at this point, after it become the metal material, user starting to demanding for the thickness of the gasket which it go to 1.5mm to 2.0mm range, that's not all, there are also user demanding for a more bigger diameter on the cylinder head gasket piston hole. The original size of the gasket diameter is about 86.2mm but due to oversize of the piston modification, gasket diameter of 87mm become their new request.

Toyota 1G Valve Cover Gasket

Previously, I'm always think that to differentiate Toyota 1G engine rocker cover gasket is just ask if it is 12 valves engine or 24 valves engine, whereby 12 valves engine of 1G-EU will use 1 piece of gasket but 24 valves 1G-GEU or 1G-GTE or 1G-GZEU will use 2 pieces of gasket.

Recently, just found there are another 24 valves engine 1G-FE which it only use 1 piece of rocker cover gasket, and for those which using 2 pieces of gasket, there are 2 types of it as well whereby one of them uses 2 pieces of same gasket and another uses 2 pieces of which this 2 pieces are diffrence from each other.

Toyota 3S-GTE Engine Gasket

Toyota S series of engine can be consider one of their most popular engine among other, from the earliest 1S series to their last version of 5S (Don't know if it got 6S onwards or not).

Among those S series engine, 3S category is most interesting in my view, as the powerful Turbo engine mostly showcase in the 3S-GTE series.

The 3S-GTE include those Celica and MR-2 Turbo which having model such as ST165, SW20, ST185 and ST205.

Kelisa Engine Mounting

When talking about engine mounting, there are more problem heard from Perodua Kelisa, Kenari type, which there are a lot of speculative explanation every way.

First they stated this Perodua Kelisa and Kenari type of engine is a 3 cylinders engine which if difference from those common 4 cylinders engine, and the design of 3 cylinders engine tense to vibrate more than those 4 cylinders design.

Another thing is this engine only have 3 engine mounting to support on it which also difference from those using 4 engine mounting.

And one of those commonly talk about is the rear engine mounting (as shown on photo) which is the biggest among 3 mounting, need to use the O.E.M parts only, which the cost of this O.E.M parts is always far costly than those normal after market parts.

There are also some mention about installation prosedure, is it change one mounting at one time or take out the whole engine and change 3 together? And some mention after installing all the mounting, which it should not be thighten fully, the engine need to be start and let it vibrate to a perfect position, than only the mounting to be tighten fully.

So anyone can give a better comment on this?
