Lots of guys have been spreading rumors about automatic 3.4 motors not having the prevision for a pilot bearing. THAT IS FALSE! At least it is for all the automatic motors I've seen.

This picture is of a 2004 3.4 out of an automatic truck. Looks to me like that's a hole for a pilot bearing.


I have a friend that's a 14 year Master Toyota Mechanic. I asked him this question a couple of years ago and he just looked at me like I was retarded for even asking. He says "it would be crazy retarded for Toyota to machine 2 different crank shafts for a motor that's built to have a 5 speed behind it".

 

good to know... i'm buying an auto 4runner this weekend

 

Here's my disclaimer. Take the above info how every you want. I'm NOT responsible if, for some reason you guys find an automatic 3.4 with out a pilot bearing hole. All I'm saying is don't be mad at me. I purchased the above pictured motor today without knowing if it had the hole or not. I don't think Toyota would have done anything different on the older motors.

I've seen quite a few 3.4's from many different years and trucks and they all had the hole. The above pictured motor came out of a 2004 Tundra.

 

ORS said they have only seen 1 in all of the 3.4 swaps they have done.

 

Do you know what year or vehicle the motor came out of?

 

Here's my 2001 auto 5VZ:

 

Humn, interesting ... thanks for posting that up. No matter to me, as I already have my 3.4 - it came from an auto tranny '99 Runner and has the spot for the pilot bearing as well; but still interesting ...

 

Just my $.02

EVERY 3.4l auto I have sold has had the crank machined for a pilot bearing

And I checked with my parts guy at Maita Toyota and there is only ONE part number for 5vz-fe crank's up to 2001 in which the change was with the snout and the balancer journal size only.

 

mine has it

 

EXACTLY , If you check with a Toyota dealer .

there is only 1 crank avaliable , wether its for atm or mtm . they are all machined on the same automated line . they ALL will have the recess for a pilot bearing .

 

Okay instead of starting a new thread.

I am about to go buy a 3.4 out of a 99 tacoma. its got 130,000 miles on it but runs perfectly supposedly. ($700) Its out of an auto and my 4runner im trying to swap it in has a 5-speed.

I just want to clarify that if i buy this motor i can make it work for my 3.4 swap..

Correct?

Thank you

Not sure what you are asking exactly but the simply anwser is: yes!

You're not going pass any emissions with the Auto ECU. Plus the wiring will be interesting.

 

Why would i not be able to pass emmissions?

Okay ive been searchign aroudn for a motor.
I just found one today, it is out of a 99 Tacoma, auto. The motor has 130,000 miles on it and the guy says it runs great.


My truck is a 5-speed, so im wondering if i buy the Tacoma motor if it will be a good candidate for my 3.4 swap. Im just trying to verify whether or not i can make it work. Now i do live in Commyfornia, but i jsut smoged my truck so i would have more than a year before i have to smog again (every other year)

But for 700-800 bucks what do you think???

 

The auto ECU will be looking for input from an auto trans. When it doesn't get those signals it puts out a check engine light.

EDIT: you could repin/rewire the harness and swap a Manuel ECU in.

 

okay. well im doing research right now and i thought people did something to the ecu to make it think its always in neutral and thats how they bypass it.



Ive been searching like a hawk on here/pirate and others trying to find the answer.
