Quick vacuum question(s)

ChaseZ · 12-25-2016, 07:40 PM

Plural because I'm pretty sure there will be a couple more lol

1. Is this the brake booster line? The diagram I have is garbage, and since it looks like heater core hose (on engine side of the firewall) figured I'd better ask to be sure so I don't end up with coolant inside the new manifold

Yea if it leads to the back port on the intake then that is the brake booster line

Yep thats the one, thanks for confirming.

And this one with the EVAP port and what looks like some sort of check valve goes into the centre port on the stillen intake between the throttle bodies, correct?

ChaseZ · 12-25-2016, 08:03 PM

Which leaves this one oddball one that wraps all the way around back somewhere I can't trace... :shrug:

EDIT: it's the one with the green dot on the fitting in the picture you posted

Jshvr · 12-25-2016, 08:18 PM

So I think the hose with the green dot goes to the passenger throttle body, if that evap port is on the passenger side then it might go to the evap vacuum hose next to the fuel feed line on the right side wall. I don't have my car so I'm just going off pictures I had from my engine removal.

I don't have a stillen intake so it's hard to tell.

So you can see the Evap port on the passenger side. Vacuum hose goes from center of intake down the side to the fuel Evap hose next to the exhaust manifold.

Ok, it must vent into the manifold on this one then.
Thanks

Dug through the FSM and found the answers I was looking for, so I'll post the images from it here in case anyone else looking for the same thing at some point. This is all pretty much clear as mud in the pieces of paper Stillen calls instructions - which should have been more technical diagrams instead of cell phone photos and gibberish.

EVAP: the line in pink loops around (post canister) and back goes to the barbed fitting between the throttle bodies

There were a couple coolant queries that came up at the same time

Coolant Flow Chart:

Coolant line from stock overflow (G) that feeds back into the system following the flow chart. Gets capped where the line enters the hard line to the heater core alongside the block. (in pink in both images)

A and F were the coolant lines going to the stock throttle bodies. Instead of plumbing them into the other side I'm capping them after being advised they would just heat soak the TB's so they are redundant. This is the line with the green dot on the fitting I was asking about above.

C is another reference to the coolant line that went to the stock overflow bottle. The stock tank is also where you would add coolant to the system before, it should go without saying don't do this anymore with the new one as there is no supply feed out from it.

These were simple things but given the volatility of the Stillen kit I wanted to be doubly sure everything I was doing. Better spending the time looking it up then shopping around for a new block afterwards

Hopefully that last comment doesn't come back to bite me in the ***!

Very informational. I'm getting the error code p0456, changed the gas cap and the code still pops up. I too did do the coolant delete so I'll make sure the hoses leading to the check valve are secured and fastened correctly.
