I just received a 3SIM to use to upgrade my car but I have one question before I start working on swapping it.

On the 3SIM I got there is only 1 hole/port for the pcv/ccv system but on my old manifold, there are 2 holes/ports being used by the pcv hoses. How would I go about blocking off one of the hoses or modifying what ever I need to be able to use it.

What year is your car and what year in the 3SIM off of? If the 3SIM does only have the one connection point then you should just be able to replace the hose from the oil separator to the manifold with the single style (which was up to a 10/2005 build date), PN 11617522933.

Mine is a 09' and the 3sim came off an 07' and mine does not have an oil separater like the early models do and mine is built into the valve cover so switching to a different hose is not an option. The only thing I could think of doing is cutting up the existing hose and using one of the connectors with some hydraulic hose that I have access to through my work to extend the hose.

I still need to get new disa valves for it and I'm waiting to install it until I get my oil filter housing gasket delivered so I can get that taken care of while I have the manifold removed so I'm not really rushed with it and can source an identical hose to the one on my car to use for some testing

I would just remake the hose you have into a single with some rubber vacuum hose and a couple hose clamps. I did that about 4 years (70k miles) ago for my manifold swap and it’s been working fine ever since. I see no reason to waste money on the oem single hose when you can just splice what you have and it works fine.

That’s probably what I’ll end up doing, do you possibly remember what size hose you used?

I used 3/4” vacuum tubing and a couple hose clamps. Just push the ends you are joining inside the vacuum line (they should fit snugly inside) and then use some hose clamps to seal it.

Awesome, I'll just do that when I swap it in a week or so
