What did you do on your 70 series today? (22 Viewers)

Hey the cracked pistons, is that due to boosting?

 

[OGBeno]

I know, I am sorry man, there was a lot of crazy happening at my job, needed to put out fires and such, so I forgot, I apologize! Does mid morning still work on week days? LMK, thanks.

Yes.

Due to neglect from the 30 years it lived in Japan. Doubt boost did this.

Crap, should I expect the same? I am only running 7psi though.

 

[mongoose2231]

OH, I just saw your reply there, pheeww!
OK, I will give you a shout tomorrow. I am going to make feast for my wife, It's her b-day today!

No idea man. I have no clue what the inside of your engine looks like.

Buy a boroscope and check it out.

Bummer on the pistons. Alfin replacements?

If it ain't OEM, it ain't going in.

Oh absolutely. That said, that's not my ideal option.

Luckily, I sat and thought about the arm situation and then had my "aha" moment.... 3B's were put into Toyota forklifts.... Off I go and pull out the conversion book:

And the rocker arms indeed crossed over:

So, called my Toyota Forklift dealer and the parts guy said these were good numbers. I asked if he could see national inventory and he unfortunately said he didn't have access to that. Bummer. So, I went ahead and ordered 4 of each. No harm in not trying. We'll see in a week or so if the arms are indeed available in Toyota Forklift format.

That's some squared away research there.

Is this bad?

I've moved my engine rebuild information to a new thread in the diesel section of MUD.

Builds - 1985 JDM 3B Engine Rebuild and Other Stories

Well, since crap hit the fan, figure it is time to do this correctly. I was planning on a head rebuild only but when I pulled head and cleaned up pistons, all 4 were cracked unfortunately. So off to the races we go. This thread will document the head and block rebuild. IP has already been...

I was about to say that. You should have a tread so its easier for us (me) to follow your work...

where can that comparison list be found? does it cover gas engines as well? thanks

 

[OGBeno]

I’m sorry— what comparison list for what gas engines? Not following.

 

[JMasi]

book:

this list/book. I know that the 3f and I think also the 3fe was used on forklifits as well.

The conversion list is probably impossible to find. Yes it covers gas engines.

The tedium of being stuck at home and inability to spend money have driven me to straight up tinkering.

I started hating on my P.O.S., two piece, non-locking, janky, Harbor Freight, bottle jack handle.
So I made a new one out of a pipe that I can use without having an arm under the truck, including an end cap to open/close the jack valve.
Then I decided I needed a special mount for it.
And then I decided I needed a machete.
Then I decided I needed a magnetic mount for a machete.
Then I decided the bottle jack handle was, along with the machete, a good attitude adjuster.

Nothing really beats the Toyota OEM bottle jack. I have a spare one in my 77.

Hit what you can with a wire brush and then saturate it inside and out with a "rust converter" sprayed from a pump up garden sprayer. Spray inside panels with a thinned out asphalt roof tar after the rust converter sets. Use "kitty hair" filler as your base filler.......If you don't drive in saltwater it should go at least 10 years before the rust comes bubbling back.

Best to have new OEM parts....View attachment 2253308View attachment 2253309View attachment 2253310View attachment 2253311

I need to do that to my 1FZ.
