77 FJ40 De smog questions (1 Viewer)

[FJ40 Jimmy]

Ok fellow land cruiser owners. I live in Ohio & have removed the air pump which didn't work anyways. Is there a way I can delete the EGR valve? Also how many of the vacuum lines can I cap off? Any help is appreciated!!

What year is your 40?

For late 2F's, there are some great de-smog threads in the 60-series sub-forum.

The short answer is, you can delete everything but these:

You can even delete the "computer", if you route 12v switched with the ignition to the fuel cut solenoid.

I think it should be a rite of passage for newbs to post links to the searches they have tried to show evidence of good faith.

GA, Beautiful work! What did you use to plug the large hole on the air cleaner?

I cut off the pipes as close as I could to the air cleaner, then put JB weld putty to fill the hole. Sanded and painted

It did have one of these, but I didn't like it.

In the link that @iptman posted above, to @FJ40Jim 's desmog parts, his kit includes a plastic cover for that hole. Unfortunately, mine split and fell off after while. It's just open now; an extra source of air but still filtered by the air cleaner.

Thanks for the link GA, I am using a black chair leg cover from Lowes. Yours looks a bit more "finished".

How do you figure that? If it's between the filter and the carb it is a filtered air SOURCE, not a filtered air inlet.

If your talking about the air pump port on the air cleaner assembly, that being open would be an unfiltered air source to the carb.

Uh, OK, I guess I'll have to go back and look more closely. I thought that the port comes in the air cleaner housing outside of the paper air cleaner, but it looks like you guys are right.

Where are you in Ohio? I am in Columbus with a desmogged 78 FJ40.

Those nylon caps can be had from McMaster Carr. You'll have to buy 10 probably but less than $10 for all and set for a while.
