Cool Saikou Michi Catch Can Install

Original thread located here-

So, about two or three weeks ago I ordered myself a set of Saikou Michi catch
cans for my Exige S (it was my first mod) and installed them on my car. The
following is a little write-up, both in regards to the product and the install, as
well as my thoughts.

There are also some pictures

So, first things first: Why does a catch can matter.

Long story short (and please, if you know more, chime in and make it more
concise, etc.)-- the pistons do not fully "seal" against the combustion
chamber. If they did, they could not move.

There is a littttttle tiny gap around the pistons that some of the gases from
combustion get past, and they end up in the crankcase. The PCV system is,
in the simplest terms, a hose connected from the crankcase to the intake
system. When the intake is sucking air in, it also sucks the gases from the
crankcase in (and sends them back to the engine to be re-combusted).

The problem comes up mainly with supercharged cars. Because of the
increased pressure from a supercharger, you have MUCH more blowby
vapor... This vapor from the crankcase also has a good deal of oil in it (both
from the engine and from the crankcase which houses the oil). When you put
it back in the intake system, this oil ends up coating your supercharger and
your intercooler with an oily film that makes the whole system less efficient.

On top of that, if you are revving your engine high, you get more and more
blowby, as well as more suction from the intake, so you get more oil and gas
and gunk coating everything in the intake. No bueno!

So, if you have a supercharged car, or you rev it high often (or both )
it is a good investment to get yourself a set of catch cans!

Now, on to the catch cans that I ordered.

The package got in pretty quick after I ordered it (nothing too insane, maybe
3 or 4 days from the night I ordered it). Here are the contents of the

The package came with the catch can, hardware (screws, etc.) brackets,
and some instructions. Fun fact: I had requested a yellow logo since my car
is yellow, but after installing it I realized the logo would be totally hidden
anyway... Oh well, A for effort!

By the way, the quality of these cans is really top notch, and I love how
they look almost OEM-- very plain and nothing crazy going on. Also, they are
LIGHT. Oh... also, they are MUCH cheaper than all the other catch cans (and
these are made specifically for the Lotus )

On to the instructions!

Step 1: Install the mounting system to the cans. Tighten them so, with a
tad of pressure applied, you can move them mounts, but they stay solid

Step 2: Unscrew the screw on the coolant tank, place the
catch cans in position, and then screw the screw back on.

Step 3: Move the other mount in position next to the aluminum bracket near
the trunk release, make a mark where the screw goes with a sharpie, and
drill a hole (sounds much scarier than it is!). Use the included hardware to
attach the mount to the bracket.

Step 4: Remove the two PCV tubes from the engine.

Step 5: Attach supplied tubes from engine to the catch cans at the inlets
(top of catch cans). Attach previously removed tubes to the catch cans at
the outlets (side of catch cans). You will need to do a little bit of cutting.

That's it! The whole thing takes about 30 minutes or so... and it is very simple. Plus, it keeps the whole engine efficient and working at its best. I haven't emptied mine yet, but I searched google for "catch can fluid" and found this picture of the gunk in one that was emptied :

That will not be going in my engine and intake system!


PS- If you have any questions, let me know. I have a bunch more pictures of
the install, but I tried to make it concise (I know, it's a lonnnng post!)
