Need information on 2.4 to 2.7 engine swap

Screw in pcv? Where would that be located?
Sorry bud, this is my first toyota so I've got a lot to learn. I surely appreciate the help.
Also when I had the breather assembly off looking for vaccum leak, I noticed the intake was bad dirty, gunked up even behind the butterfly as far as I could see. Idk wat would cause that. The air filter was pretty clean. I just hope I don't have to remove the intake to clean it if and when I get the sensor problem fixed.

When you clean the throttle body.....angle it so no solvent gets into the electronic parts


Before you take anything apart.....take numerous pictures
so you know where everything goes back

maybe a little video scanning what you are about to take apart



Pretty much anything you can think to do to the truck there will numerous youtube giving different angles, approaches, tips

 

Thanks O'silver!

 

Top problems in these trucks as they age is bad battery connection/ pooor ground(s)

and old rotten vac hoses......thats one of 1st things I replaced......all those hoses
it'll never idle right otherwise.

 

Looks like they took care of that pretty much when they swapped engines. But with all that gunk, could have built up since the swap so that's something else I'll check.

 

Your lucky the 2.4 is really gutless with the auto trans....
....with the 5s manual its a little better...

the 2.4's run cooler and can last a very long time.

 

Idk how it's even running. especially idling smooth and everything smooth. The air fuel sensor isn't doing anything. it's dead. If it wasnt so weak and doing better than 15mpg I'd just leave it alone lol.

 

I would carefully check the wiring going to mass air flow sensor......the forward ox sensor....
and the ECT temp sensor on back of engine


those three control the engine.....


I have heard the pcv can cause increase fuel and oil consumption when leaking or stuck....

 

Will do!

 

I would get you a BT dongle scanner....

I saw that earlier n thought that may come in handy

 

As you have problems in future......everybody that tries to help you is gonna ask for numbers.....

 

Trouble codes?
Can I test that a/f sensor on bank 1 with a multimeter and tell for sure if it's bad or good? If so, it may save me a lot of time looking for possible wiring issues.

O'silver you're the man! And I just found my pcv valve was stuck shut

 

Yeah by their nature they gunk up

 

Anyway that's 1 thing down. Only 1,317 more things to check..lol

 

yeah 6 yrs later......I'm nearing the end of the list.......dont even want to know the cost...

its been a hell of a journey....

 

I hope mine last long enough to go through that list.
Unrelated quick question for ya Silver...
I'm getting a wet pass side floorboard. pretty sure it's the Ac drain. It flows out the tube on firewall outside really well. Is there something else on the inside that would cause it to leak?
I love the Ac on this old truck. It blows frostbite!

 

Theres not 1 speck of rust, (miraculously), on this 24 yr old booger and I'd sure like to keep it that way.
