: Installed Saikou Michi Dual Catch Can tonight (PIC)

08-10-11, 11:17 PM
Got the can today. Installed it and I now have tapped the fresh and foul air lines. Too tired to take more pics of the hose routing or to even add clamps. Not necessary to have clamps but plan to add them anyway just to make sure there is no possibility of pressure loss. Sorry about the pic quality, it was from my blackberry.

I will say there is an in and out for each can and one can is for fresh air (off the valve covers to throttle body( and one can is inline with thevalley cover port (foul air line).

I will take more pictures with my D90. If anyone is interested in the routing of the hoses, just ask and I will respond tomorrow with additional photos.

For now, I like the can alot. It is very light and the quality is terrific. you can do a search for Saiku Michi if you want to look at the product internals. Alot of corvette and camaro guys run this.

I probably won't cat much off the valve cover (fresh line) still wanted to filter both fresh and foul lines.

The can came well packaged and had great instructions. It was a pleasant surprise from the other can's U have used over the years on different vehicles. I didn;t need them cause I already knew where to tao what. Great price too....

I may have to rename the engine bay to WORM BAY as it is starting to look like a container of worms. Don't care though.

Looks great Curtis I would like to see more pictures of the install if you have them!

I will in the next few days. Next is to install the nitrous dedicated fuel system

Vetkilla let me explain the routing

You have the fresh air line which is the hard plastic line that comes to a tee off the valve covers and then goes into the CAI tube.
I removed the connector from the hump hose on the the tube as I wanted to leave it only connected to the tee fitting hard hose. I then attached a 3/8 hose to it and routed it to the foul nipple on top of one can. I then inserted a straight connector nto the hump hose and rand a 3/8 hose from it to the side nipple on the same can,

For the foul line. You will see a connecting ribbed tunbe about 6 inches long that is located on the valley port. I cut this connection in the middle and clamped a
3/8 line to each end. The end that exits the valley port was routed to the top of the other can and then I routed a 3/8 line from the side of that can to the other end of the spliced 6 inch ribbed foul line. So basically you are putting a can "inline" on the foul line and the fresh line.

I hope this helps a little unitl I can get pics up.

My engine bay looks like a can of worms.

You opened it.

Thanks Curtis!

Ok, here is what I did:

The foul line is a small 6 inch or so ribbed tube that connects to the valley port. If you are facing the engine, look just below the supercharger on the left front of it and you will see the connecting tube. I cut this and attached a 3/8 hose to either side. I ran the bottom of the hose to the dirty inlet or top of one of the cans. I then ran the top part of the connector to clean or side port on the same can catch can. So in essence the can was just put in line to filter the foul line.

Next was to address the clean line. The clean line is the stock configuration of hard tubing the runs from either valve cover to a "T" then into the CAI tube just prior to the throttle body. I removed the connector from the cai and replaced it with a straight connector. I then ran a hose from that connection to the clean or side port on the other can. I put a hose on the "T" line and tan it into the top of the can. So in essence I again put the can in line.

This is the foul connector I cut and attached 3/8 hose to either end

This picture shows how I connected to the fresh line, where the valve covers "T" into the cai tube

I hope this clears up the routing questions.

Thxs. For all info. What part model of catch can and does it have drain lines?

08-12-11, 03:50 PM
Do a search for Saikou Michi catch can and you will see the site. It does have drain lines at the bottom of each can. The internal schematics are on the site as well.

The only thing it does not have is a dip stick, which my old can had and I thought was genius. I ordered the LS1 dual can.

I do not think I can put their website up or I would. I have bought my share of cans and thought I'd try it as alot of the vette and camarro crowd love it.

I am pleased.

08-12-11, 09:20 PM
It's obvious you're not shilling for them, just a private buyer so I don't think you'll have a problem poasting the site...

In that case:




What was great was I contacted them and had them switch the side that the mount was on and switched the side of one of the filtered outlets.
They can customize it any way you need it for your specific mounting location. The can was designed, ordered and received in 10 business days.

Let me ask the dumb question, what does this do?

08-13-11, 07:34 AM
Fairy good answer from WikiAnswers

An oil catch can is used in turbo applications, or high-performance race applications where excessive blow-by (leakage past the piston rings) of air and fuel vapor occurs. This creates a positive pressure in the crankcase. Engine manufactures have placed a valve on the engine block which releases this pressure. This valve is known as a PCV (Positive Crankcase Ventilation) valve. During engine operation, blow-by gases, as well as oil mist from the rotating components of the engine, pass through the PCV valve and are routed back into the intake for the engine to burn off. However, some of the oil mist and other products settle along the engine intake and over time form a "gunk." The oil catch can collects the oil mist and condenses the fuel vapors while allowing "cleaner" gases to be passed back into the intake. Typically the blow-by gasses are passed through a wire mesh, which give the vapor droplets something to adhere to. Since the oil catch cans condense the vapor portion of the gasses, they will need to be drained periodically of all the oil, fuel and other contaminants.

For those interested in how I deviated from the normal mount on an engine bolt, I will go over what I did.
1.) makes sure you let Mr. Serrano (Saikou) know that you want the mount reversed to the other side and you want to fresh outlet nipple put opposite it normal position. (look at my can vs the pic on his site. It should be clear).

I wanted to get the can as far away from jeat as possible and still have access.

Hardware used:

2 3/8-16 Rod cpouplin Nuts
2 3/8-16 X 3/4 inch hex cap screws
2 3/8-16 X 1inch hex cap screws
2 lock washers
2 flat washers
Blue lock tight

You will have to rheem out the holes on the can mount to accept the 3/8 X 3/4 inch hex screw with locking washer, as the original hardware was not as
heavy duty and the holes were smaller.

Remove your CAI tube for more room and take time to clean dust dirt and bdbris idf present.
Jack up the front driver side so the wheel will hang and give you access to the holes with ease. The tire willl hang down so you have room to get you arm and hand in there easily. I used 9/16 socket and wrench.

I placed the mount on the side of the engine bay fender well and marked it. Make sure you are mindful of the couplers will be there and the can will sit about 1 1/2 inches forward of the marks (due to the couplers being in place). Also be mindful that the hood will not hit the barbs on top of the can when you close the hood. I also taped a towel in place to grab all metal shavings and simply wrapped it up and threw it away when done. Any shavings that may have escaped vacumn up at this time.

I the added lock tight to the longer 1 inch hex cap screws and put the flat washer on them. These were pushed through my drilled holes from the fender into the engine bay. I screwed on the rod coupling nuts. Do not tighthen at this time as you may need to position them slightly to line up the holes on the can mount.

I then put the can in place and put lock tight on the the 3/8 X 3/4 hex screws added a locking washer and screwed them in. I tightened everything up.

It is going nowhere! LOL

What do you use to polish your intake?

08-13-11, 03:08 PM
So, you'd agree with the assessment that for a typical road driven car, a catch can is unnecessary?

08-13-11, 03:54 PM
I would tend to lean that way. I do believe it is helpful though.

08-13-11, 03:56 PM
I rarely polish it. I have a dye grinder with various cloth buffing wheels and jewelry rouge if I feel like getting industrious.
