Need help, what are these hoses for in 3F engine? (1 Viewer)

[claudiosalva]

People,
Doing some maintenance last week, I had a flush on the power steering, rebuilt it, and then install it back. Somehow these two cables are on the "loose", they surely look like air is going through them but cannot find where it goes.
Hint: close to the air filter but checked close to the air intake, the manifold and it's not missing anything.

Thank you @Marco Lau ,

So, this means that is going attached to the thermostat case?

I am not 100% sure now....can you take a pic of where those 2 vacuum lines attached from the other end? I will try to take a pic after work on my engine bay...

 

[claudiosalva]

Thanks, man,
Yeah, I just double-checked and saw that the lines are going to the air filter. I have a Safari snorkel and probably that could be hoses that going to the air filter??

 

[Marco Lau]

they go here..sorry for the delay

 

[claudiosalva]

Thanks,
My understanding is that they are going to the top of the engine block am I right?
I just rechecked close to the top air module but didn't see anything missing at all.
I will post some pictures here as well.

Now have some time to look at your pictures closely. I am positive you have a couple vacuum lines hooked up incorrectly. Mostly between the air intake and the manifold. Look at this diagram closely and trace the lines and cross reference the diagram. It is a bit confusing. But I think I saw the problems

 

[Marco Lau]

Sorry, this diagram attached. Also can be found under the hood, tells a much clearer picture of where the line goes

 

[claudiosalva]

Thanks for your help. I still trying to understand where the cable goes because even tho I got the diagram cannot find the solution.

 

[Marco Lau]

Start from the intake box, trace the lines, those are not hooked up and obviously something is not hooked up correctly on the emission side and not seeing correet vacuum, and your EGR might not be working properly.

 

[claudiosalva]

Ok , will do. Thanks man

There are 2 vacuum lines that go into the distributor cap. I do not see them on what appears to be an aftermarket Cap. Your pictures do not show the Dizzy cap very well. They are larger than the other vacuum lines and are 2 different sizes. Are yours connected?

 

[claudiosalva]

@Heelerdude , Yes that's true. I bought an aftermarket one after that distributor cap was already worn down. I will attach a picture.

@Heelerdude
The lines are not connected to the distributor cap, perhaps these hoses need to be connected to the DC?

 

[Heelerdude]

If it’s an FJ80 those lines most likely go to the cap. One of them goes over to the firewall and into the cabin. The other goes up to the air box if I recall. You should get an OEM DC cap, I have read that lack of ventilation causes dizzy failure

 

[claudiosalva]

I think we just found the problem. I saved the old distributor cap, any thoughts about the condition?

The only reason that I changed the OEM is that I was doing a full tune-up and just added a new cap supposedly high quality from Napa Auto Parts. Probably I can re-install this one instead, any recommendations?
Thanks in advance

 

[Heelerdude]

I would clean it up and re-install. Make sure the ports are clear. Google 3FE distributor cap vent. There is info on why it’s needed.

 

[claudiosalva]

Appreciate it!! @Heelerdude

Instead of playing games with used non-OEM parts for the ignition system, do yourself a favor and get new OEM parts. The 3FE will spit aftermarket ignition parts back at you and you'll wind up doing it twice.
3FE dissy cap: 19101-61240
3FE dissy rotor: 19102-61240
3FE dissy gasket: 19127-61240
3FE plug wire set: 90919-21503
3FE plugs: 90919-01091

Can be purchased from any Toyota dealer or as a package from:

The OEM cap looks like this: Black with "DENSO" across the top. HINT: DENSO should be facing you when you install the cap.
