If that rail is off of the 1FZ-FE engine that part is NLA from the dealer. So if you need a factory new one, you'll have to contact Beno, because he bought the last ones available for his shop.

And another one bites the dust....

23807-66020 1FZ-FE fuel rail.

I bought the last 7 available.

These are long gone.

What reason, other than cosmetic, would someone replace the fuel rail?

I am mostly worried about the shape the injectors are in.
how much carbon should be present on the injectors and in intake manifold open?

My '92 had a lot of carbon in the intake and on the injectors after 300,000 miles and looked worse than yours. I cleaned everything up and replaced the seals and o-rings. I also replaced all the electrical connectors on the wiring harness since they were brittle and a couple of the locking tabs broke when taking them off.

Do you have a link to those connectors? Mine needs a few...

I took the connectors off the wiring harness from a 2001 4runner with 3.4L v-6.

Did you do a complete engine overhaul?

Head gasket. I got a complete gasket set and replaced pretty much all seals and gaskets except rear main while I was at it. Everything I could get to without pulling the engine. No more leaks! I also replaced the oil pump since I had the pan off, but it didn't really need it. I could still see cross hatching in the cylinder walls and there was no discernible ring groove.

High impedance connector? Where do these morons come up with their descriptions?

I seriously hope that the connections are LOW impedance...

do I need a puller to remove the big gear on the intake cam?
also can I bypass/close off the EGR?

No
Yes

You do need a FSM, or
Factory Service Manual.

Your gonna like it.
Sometimes it takes a bit of browsing to the part you want, but when you do it's all there.
