just curious if i could eliminate all the evap stuff, will it run right if i do?

cartune777

hey all im in the middle of doing a 3.4 swap and im curious if i can eliminate the evap system, there is no emissions tests here so i dont need it, but will it run right?

cartune777

do some of you guys have no evap on your tacomas from the factory?

cartune777

just asking cause there is no connections for it in my harness

cartune777

does anyone know what this connector is for? its in place of where the evap stuff is

RobD

I'm not running any of the EVAP stuff and can't tell if there's a difference, or not, since I never drove the 3.4 prior to swapping.

If you can get a better pic of the connector, I might be able to identify it. It looks like it might be the EVAP connectors. I'd have to look at my engine, but I'm pretty sure I just left those to up near the firewall.

i see, well i think im not gonna hook it up, do you have a knock sensor cause there is none on my motor, its blocked off

RobD

Knock sensor?

Or do you mean EGR valve?

cartune777

nope all my egr stuff is also blocked off, dont these motors have a knock sensor threaded in the side of the block? if so i dont have one

It will run just fine,but you will need to vent the tank and block the evap ports on the intake........Then you need to deal with the CEL staying "on"...

bwhyit

You can take it off if you'd like but like 97ltd4x4 said you'll have to deal with the CEL on. Your not really going to gain anything by removing it so I'd say leave it on.

The 3.4L has two knock sensors under the intake manifold, same area as the 3.0L.

cartune777

ahh ok, thanks for clearing that up, that one wire plug must go to the ac then

RobD

Wow...that is the cleanest 3.4 I've ever seen! Mine looks nothing like that!

cadman

The most gratifying things about rebuilding an engine are (in no particular order):

1. The engine is essentially new.
2. You know what condition it is in.
3. Everything is CLEAN .

cartune777

yeah that looks good, does the fuel pressure regulator vacuum hose plug straight into the manifold or do i have to hook it up to a vsv? if so which hoses go where on the vsv?

cadman

I don't remember off the top of my head so I'll check it out for you after work.

cartune777

awesome, thanks

It looks alot like this one:

cartune777

i think im going to remove all the evap stuff.
