New 1FZ shortblock

[OGBeno]

Love it, I'm learning from 2 of the best.

I'll run out to the shop and see what I can see.

Dan and I take 11400-66041 very seriously.

Th e 1FZ is a "select fit" engine. This means that every main bearing interface, connecting rod bearing interface, and piston-to-cylinder-wall interface is tailored to that specific location.
This is one reason why the engine survives as well as it does.

Storage has been good, I switched to a gun safe goldenrod electric heater dehumidifier in contact directly with the block and seal the bag up tight.

I have a steel building metal shop and the temperature swings are huge whether it's summer or winter time as well as lots of moisture in the winter. I didn't want to run the risk of the dehumidifier bags getting absorbed and then having flash rust, So the dehumidifier electric rod made the most sense.

So far so good. Everything looks fine. The summer I took it out of the box flipped it over and inspected it all around. Everything looked good.

I plan this winter to get a new engine stand as I don't have one get it mounted and as my pro motor friend suggested put a teaspoon of oil in each cylinder for the rings as well as a light coat of oil all around.

I plan to source a new factory head this winter as well as a few odds and ends. As I get closer to building the motor I'll have the head put together or do it myself. I haven't decided. I've got the FSM and I'm not in a hurry to build the motor so I'm wondering if I could do my own valve job. But again I have a friend that's a pro. I might just take it to his shop.

@BillyGoatMTB This is great! Thanks for the details here - goldenrod seems to be the ticket if yours looks as good as it does with those temperature swings - thanks for the feedback!

Regarding adding a teaspoon of oil as your friends suggested; would you do that when it is still just a short block? Or once the head is on?

Again - thanks for the info!

Very interesting @cruiserdan

New factory head will be all time perfect! I hear ya on how to tackle the assembly when that time comes - definitely keep us posted.

Are you picking this up locally or getting it shipped freight? I called and spoke to a few dealerships including Olathe. They can’t give me costs until I order one but there are none in the US currently.

I am going the shipping route. I am ok with as long of a lead time as it takes - just happy to secure one!

Right, I absolutely love my 80 and when I took possession of the short block I literally had a huge sense of relief for the future.

I need to get a head next.

And I have a correction. My block is not stamped for the year 2023. As far as I can tell. I believe I got it mixed up with the label that shows it's from 2023. It's been a year and a half.

Yeah the golden Rod's been in here. It seems to be working great. I have a couple friends one races go-karts and has built many engines. He was over the other day giving me a hard time telling me to get it up on a stand and get it oiled

The goldenrod seems to be working fantastic. I check on her every couple months just to make sure everything's cool and there are factory desiccant bags inside the bag I just noticed.

I'm excited and honored to have one. I made a correction about mistaking the shipping label and the year 2023 on the previous post.

Without taking the short block out of the bag, the only markings I see are on the left hand side next to the oil filter intake, photo attached. I also found a picture from March of 2023. I'm assuming these are bearing numbers?

Do you have an opinion on storing this thing? Should I get it up on the engine stand and get everything oiled up?

Obtain a service manual to get educated about assembly procedures. keeping everything dry and clean should be automatic.

Dry and clean has been the goal, and I have an fsm.

I get a mr t fsm for all the vehicles, learned the hard way on my 1998 Tacoma trying to use a Haynes, the 4 book set has paid for itself many times over.

Recently picked up a 2021 Tundra but I don't see a factory service manual available for that. Is that some online subscription I'll need to get?

 

[cruiserdan]

The newer stuff may only be available online by subscription. Around 9 years ago Helm took over Toyota manual publications. Maybe they have an application for the Tundra. All the dealer-level stuff is online, behind a paywall.

Love this picture! Just so I know, is the golden rod wrapped in plastic before touching the metal? Or is that just the excess bag wrapped over the rod as it sits on the block? Thanks for sending this!

When I learned they were still attainable, I got that much more excited about finally owning an 80!

The rod is currently sitting on top of the block, similar to a gun safe the theory is and air in the bag Will be warmer than any ambient air that would enter the bag reducing or eliminating condensation.

I'm an electrician, not a metallurgist It's just what made sense to me to keep condensation out, I mean why wouldn't I treat this magnificent piece of engineering the same as precious firearms? And why would I trust a desiccant bag that can get absorbed and not warn you?

My plan is to get it up on an engine stand and then I will either zip tie or wire tie the rod to the bottom of the block. This way warm air is constantly moving up through the block. My Hope is the block becomes a thermal Mass and always maintains temperature above outside, cold, moist air keeping any condensation from ever occurring.

I also plan to put a tablespoon of oil in each cylinder to keep the rings happy.

Oh there it is on the other side - gotcha!

Relieved to know the plastic can touch the rod and all is ok in there.

I have to say - you are the man - really appreciate the replies! Couldn't agree more. Have a good day out there!

 

[BillyGoatMTB]

On another note, has anyone built their own new 1fz head from scratch? The FSM and process seem relatively straight forward.

Or is the consensus this is definitely something to bring to a capable and competent shop?

Hey, thanks, it just sort of made sense to me.

Happy to share. I mean that's what the Land Cruiser family and mud are all about anyway right

You have a good one too.
