First i removed the radiator bolt for the mounting bracket. Its the bolt just to the right of the radiator hose.
Next i cut the plastic off of the left side, to fit the bracket. I used a file to smooth the surface.
I installed the bracket after having to find a longer bolt to fit.
I then located the vacuum tube on top of the valve cover and removed the 90 degree clip. See the little nipple sticking up off the valve cover, thats where the hose is clamped to.
Next i cut the clip off within a few inches after the end of the 90. As i cut it, i squished the tubing a little bit. I used a circular chisel to regain its shape, (you can use whatever you want). To remove the clip, look at it closely, it comes towards itself and then to the right...
After that i took the hose and a clamp and clamped it to the valve cover orifice. This tube leads to the center (90) of the catch can.
After that i slid the hose onto the tube i cut the 90 off of, (this tube runs from each side of the intake manifold and come together right before the 90 on the valve cover), this hose goes to the other 90 coming out of the catch can.
Here is the end product.
Note: It will be easier to loosen the intake tubes on each side so you have more adjustability for cutting and placing the hose and clamps on.
Its easy to make to be honest. But i understand why you dont want to wait. A month is a long time. I got mine within a couple weeks and then got the new bracket a few days later.
Looks like i will contact him cuz i didn't make it to the office, when i got out, a punk kid i told not to sit on my car, came during the evening and knifed one of my tire (1st time in my life i'm saying this but : thank god for nosy old ladies) my neighbor saw it so at least he's gonna get caught cuz the mom is a deadbeat and didn't want to hear about it, so had to call the cops and do a report and all
and my damn tires are rare in canada (330$ each) what a shitty day gonna be on the donut for couple days till they receive the tire no one has it locally
sorry didn't mean to switch subject, so didn't make the bracket and won't be in the office for 3 weeks, so might as well get the real bracket
Short, is there any particular reason you attached the hose directly to the PCV tube rather than leaving a couple inches of hose coming off the fitting and connecting to that? Both accomplish the same end result, I am just wondering if you chose to nix the stock fitting for a reason.
Nice write up!
But you should've cut it with couple inches from line coming off orfice that way you can put it back stock when u sell or have emission test. I've heard they or back ordered..
I don't think they're back order, went to caddy dealer yesterday to get one in case and got quoted 49$ with a 6-8 days delivery time ( that's in can$ i'm sure it's cheaper for our american neighbors
I heard the PCV tube was on backorder as well, but I ordered mine at the dealership without a problem. The PCV tube was $15 and the fitting for it was $12. It was less than $30 for both.
Helps keep the oil out of intake. These cars are pita with sucking in lots of oil and just blow by from the pcv system. The catch can stops a lot of it.
Welcome to the forums! Make sure to check oil level some of the cts love to drink oil.
The catch can intercepts oil in your positive crankcase ventilation (PCV) system before it gets cycled into intake (to be burnt in the combustion chambers). Oil doesnt burn as well as gasoline, and so the computer reads it as a lean burn and retards your timing, stealing power. The catch can just keeps the oil from being recycled into the burn cycle of the engine.
The catch can is usually used in conjunction with a opened up/drilled out/modified PCV metering tube. The LY7 doesnt have an actual valve in the PCV system, and just uses a tube with two holes in one end and one hole in the other. A lot of people drill out the larger of two bottom holes and the single top hole out to 7/64". This is because these metering holes are prone to blockage and if the crankcase does not get proper ventilation it can cause all sorts of problems, and the larger diameter holes are less apt to get plugged.
It is an excellent preventive maintenance step to keep your valvetrain clean and ensure you get access to all the power your engine is capable of producing.
I hate to quote myself from the same thread, but...
And, yes, a system like this would be beneficial to any vehicle that has a system in place to vent crankcase case, and thusly engine oil, into the combustion chamber... all modern street-legal vehicles employ such a system to comply with emissions regulations.
Sorry if this was mentioned, but I'm interested in doing this soon - found out the new to me CTS is an oil burner - 1/2qt in 1500 miles. Anyway, I'm on the revxtreme website and I see a catch can with a dual check valve and a single, which is the one I want? I may end up just calling them to order, what do I need to specify besides vehicle? Longer bracket and ..?
Get the single check valve, i would also suggest that you get the filter cap as well. I dont know what bracket you need, you have an 04. It might mount somewhere different. Im not sure if you will need longer bots or not.
I would jump all over it bud but I am on the other coast now.
