Do I need these sensors and valves? 2005 SS/SC

.

I will give that a shot.

 

[Rttoys]

Nothing to it. I think there’s a step by step here somewhere, but it’s really not that difficult.

Do I keep this filler neck?

Do I keep this filler neck?

It looks like I broke the tab, if I need to keep it I will need to weld that little tab or make a new one.

 

[Rttoys]

Ya. Gotta have that.

 

[Rttoys]

There are larger reservoirs out there though, if you need one.

 

[Whidbey Goblin]

I know one is for the fan and one is for the AC pump, what is the little one in the middle?

 

[Rttoys]

I think the round 3 prong is for an ac pressure switch?

 

[Whidbey Goblin]

I think the round 3 prong is for an ac pressure switch?

Oh, yes. I see it on the AC lines so I assume I can clip both the AC plug and the pressure switch plug and just dead end those wires?

 

[Rttoys]

Yep.

 

[Whidbey Goblin]

Yep.

I really appreciate your help. I’m learning a lot.

On my go carts and motorcycles I always eliminate this rebreather line, Cap the one on the intake and put a small simple filter near the valve cover. Did you keep this line or get rid of it?

 

[Rttoys]

Some do, some don’t. I kept mine routed back to the intake, like stock. I could go either way though.

I did a video of gutting the AC compressor. Saved 5 pounds.

While I got rid of mine and just put a filter on it, I consider putting the hose back on. With just a filter, the crankcase pressure that builds up has to blow through the filter, if it should ever get clogged, you can build up excessive pressure in the crank and blow other things. I've noticed our valve cover gasket weeping a bit and I can't help to wonder if it's because of "pressure" in the valve cover and not having the intake "suck" out the built up pressure. During WOT and high boost, this really comes into play.

Oil in the intake obviously isn't a good thing either. Get a universal catch can and put it in the middle of this line, but keep it attached to the intake like mentioned by @ctuinstra. Boost will build crank case pressures and blow seals/gaskets eventually otherwise.

 

[Towerdog]

Due to the pressure it blows alot of oil into the intake so I routed mine through a catch can.

Curious, how much oil do you collect over time?

Have you been running this motor for a while with the AC compressor this way? I’m a little concerned it has lost strength by only having two bolts hold it.

 

[ctuinstra]

You can keep the shell and use the third bolt. That's what we did. It works either way, just preference.
