5VZFE Engine Out Refresh - Parts List

[CoCoCo4Runner]

Hello, I'm finally getting around to swapping my 3rd gen and have sourced a replacement motor. It's lower miles, but while it's out I'd like to have it squeaky clean and as renewed as possible.

So far, I've purchased the following:
Gasket Set - Toyota 4Runner, T100, Tacoma, Tundra V6 3.4L, 5VZ (1995-2004) Long Block Install Gasket Set Kit-2023

Timing kit- Toyota V6 3.4L 5VZ-FE 4Runner, T100, Tacoma & Tundra Aisin OEM Timing Belt Kit with Water Pump, NO hydraulic tensioner (1995-2004) TKT-005

Plus some additional parts from a local dealer (see image)

Is there anything else I'm missing? I don't want to mess with the internals, headgasket should be fine (assuming it passes a leakdown test). I also have new LBJ's but that is not strictly engine related.

Thanks!

Looks like you've got most of it covered. I'd recommend adding an OEM thermostat and heater core water valve to the list. Maybe an IAC gasket if you haven't cleaned the IAC in a while.

EDIT: That's the wrong part number for the PCV. I only checked the PCV part number because it looked weird to me. I didn't check any other part numbers.

Might be worth rebuilding the starter and throwing new brushes in the alternator. Pretty cheap parts relatively easy to get to any time but would be really easy to get to with the engine out. Might also be worth re sealing the engine oil pan while it’s out. Last thing I can think of is rear main seal.

Yep on the starter. I rebuilt mine put it in the engine bay and within 6 months I was pulling the starter for contacts.

Spend the extra money on the high volume oil pump. This engines oil pressure at idle is way low compared to what I’m use too.

New Aisin fan clutch. You want that engine running as cool as possible. Should be p/n Aisin FCT-013

Well, it’s all for naught. The motor I picked up has some funky exhaust valve issues. The wrecking yard I got the motor from recommended I put some oil on the valves and try it again, so I popped off the valve covers and added oil, spun the motor and it made no difference.

I paid too much for an engine with valve issues, so back to them it goes. Shame because the other cylinders were pretty tight. I’m sure this would run in my truck but I doubt it would run particularly well.

Have them contribute to having the bad head freshened up.

The next one you get may be worse. When I buy used engines I want to hear them run before it’s pulled.

I tried pitching that to them, they said they’ll pick it up and refund me. Oh well, keep on looking

used engines are a crap shoot. hopefully you can trade that one back for a better. glad you checked b4 putting it in. some yards have a print out of compression etc on the used engines that they do b4 pulling. That is if you can trust that. In some of their defense...of even a good wrecker...they really dont know...and a dry compression test can fool you and them. I totaled a nice yota...that I knew had a slightly leaking head gasket from an over heated engine...blew a radiator hose in the middle of bum frick no place...( had just started to leak shown by a leak down and radiator dye test) and I bet the limited test that the wreckers throw at it would not show.

Sadly it’s how business are run these days. Someone will eventually buy that engine. Or they will fix it and resell it.

Yeah I don’t hold much value in compression tests, might as well just too a leakdown, it will tell you all the pertinent information and then some.

Is this a rig you plan on keeping forever? If so, I'd save up for a quality rebuilt engine. Since you're in the Bay Area like me, there's an engine rebuilder I can highly recommend and that's Yota1 Performance in Riverbank, CA near Modesto.

A Yota1 Performance engine is featured in this video series.

To add to the list of parts for an engine swap, It's smart to replace the knock sensors and knock sensor wiring harness while you have the engine torn apart. At the very least replace the harness because they get brittle and fail.

Good list developing - I'll second the oil pump why not since it'll be staring at you doing TB.

If you buy the YotaShop head replacement gasket set it includes the knock harness.

Of all the members that replied to my oil pressure question, I have so far the highest oil pressure at a hot idle (after 31 miles of driving above 90f ) in gear at 600rpm in drive with foot on the brake.

If you are up for a challenge and want to install a JDM motor (a lot of parts need to swap over) Venus Import in southern Sacramento is where I got mine. Top notch customer service and did the compression check right in front of me (220 PSI on all cylinders).

It'd be best to call them as their 5VZ-FE's sell out almost immediately so aren't listed on the website. Welcome to Venus Imports | JDM Engines & Parts at the BEST prices

I didn't see a question in your oil pump post just truth. If not a hp pump at least a new one,
the hp pump would compensate for clearences loosening up with normal wear.

I bought an Asin pump and my starter doesn’t spin it fast enough to make the oil pressure light go out.

I did completely clean and flush the oil cooler. About a second after engine run the light goes out.

I'd do it in a minute with a place like that just down the road, CH to Sac what 20 mi.
CA has the best and most JDM places, in the SE forget it.
I'm going to call Venus for the hell of it to hear shipping cost for 1800 mi in these times bet it same as cost of engine Ha.

Doing a apples to apples that's how mine works @224k mi,
key at on posiition light on, engine fires up 1-3 sec hold in Ign position light goes out.

Are you cranking longer than that ?

I've cleaned oil cooler new hoses o-rings, did pull oil pressure sending unit flush with cleaner only difference.
