Searching for 2B Head Gasket

[RedHeadedStepChild]

I'm looking to pick up a new HG for the 2B in the 44. Can anyone point me to a good supplier.

Radd Cruisers has been helpful, but they can't seem to get a reply from their supplier in AU.

Found one on eBay (from Gaskets4less) for the Dyna, Coaster and 44. Ordered it up and a day later got an order cancellation because they are out of stock.

Don't trust Cruiserparts to send the right thing (they installed the current gasket and I'm boiling coolant not all that many miles later).
******EDIT***THE CORRECT GASKET WAS IN THERE**********
I recognize there may be larger issues I might find when I pop the head off, but right now I can at least move it out of the garage and around the driveway if I need to work on the 4Runner. I'd like to have the gasket sourced prior to pulling the head.

Try http://export.japan4x4.com/ they have found parts for me in the past

Thanks Dieseler,
email sent and fingers crossed...

Order it from Toyota. 11115-56120 is the part number for B/2B/11B. It is possible you have the wrong headgasket and it is blocking the coolant passages.

For an August 80 to October 82 BJ44 I instead see 11115-56020
subsituted by 11115-56021

11115-56010 is the number for a B HG not sure where you are referencing 11115-56020 as being the same gasket for the 2B
The 2B HG gasket is not available in Canada or USA from the dealer it is Japan specific JDM only 56020 is a 3B HG
There may be some LC parts suppliers like 4 Wheel Auto or Cruiserparts who are stocking it specifically for the 2B

Based on some discussion on the BJ44 Registry thread : https://forum.ih8mud.com/diesel-tech-24-volts-systems/504561-bj44-46-registry.html
I think I have an '81 built in Nov. of '80 (Vin: BJ44-001666)

I suspect that blocked cooling passages from an incorrect HG may be the case.
Cruiserparts did the original work ( I bought the truck from them). I've seen other threads on these HGs where people have purchase 3B gaskets or been told a 3B will fit, and I'm afraid that's what I have here (I'll post some pics up when I pull the head) so I don't have confidence that they'll get me the right part.
***I should note that at this point, this is pure speculation on my part.***

I'll try these P/Ns at my dealership, though historically I get blank stares from whomever is running the parts counter and have been told that Toyota doesn't make ANY diesel engines so we'll see where it goes...

These parts are not available to NA dealers.

This part is available in the US.

Using the P/Ns you all so graciously provided, I've been cruising around the web (I should be working) and came across a site called Amaya.com. They claim to have an HG in stock, but the website originates in Russia so I don't really love the idea of tossing my cc info into their system. Has anyone used these guys?

beno - I Left a VM at your dealership

This is not going anywhere Canada dealers can get parts for the B and 3B ....US dealers will look at you with a gaze because their data bank does not carry those part numbers.
To get the proper head gasket.... order it direct from Japan then you will get what is needed no mistaking the part if you order the correct part number. The problem with a 3B gasket it is the same size but the passages are located in different locations and the 3B gasket change several times relating to design chages over the years. The B is also similar but not the correct one either.
11115 2B GASKET, CYLINDER HEAD
11115-56020
There is only one guy in the US who has any chance of getting non listed parts goes under the name CDan

Are you sure it is the head gasket when you remove the rad cap does it bubble when running if there are bubbles rising up it is either head gasket leaking or a cracked head.
Do you have signs of oil in the the rad or water in your oil.
when you do end up pulling the head post some pics of the gasket beside the block so we can see the passages in comparison plus post pics of the new gasket next to the old one need the info for my data bank.

Dan won't be able to get this either. I know this for a fact. Nor will I, nor will anyone in the US or Canada.

David Stedman in Japan would be my first choice. (Japan4x4.com)

Its boiling the coolant to the point where it will blow out the vent on the overflow tank. I haven't tested to coolant and really the whole system needs a really good flush, because whats in there in gnarly.
I REALLY HOPE its not the head, but I can't say yet. I was hoping to have a gasket in hand or at least on the way before popping it open.
I'll Post some pics when I get into it.

not sure where you are referencing 11115-56020 as being the same gasket for the 2B...

Here's one for $4.60 .... LOL. Sounds very suspect at that price...

But.... you got me thinking.... (Dieseler & co always speak good sense so what they say should never be ignored.)

My 1979 BJ40 with B-engine was built using a 11115-56010 head gasket and 11115-56120 certainly appears to work for her...

Here's some pics I took comparing the genuine Toyota 11115-56120 with the gasket supplied by Engine Australia with their B-engine recon pack:

Ist the 56120 gasket by itself:


Comparison with the Engine Australia gasket:



I don't suppose you have the original 2B gasket there RHSC so we can do an image comparison?

And do you know the part number of the gasket that on there now (that may be the culprit for your coolant overheat problems)?



PS. Failing that, shoot some dead-on images of your head and block and maybe we could try to use them with my 56120 gasket to see from the images if we have a match?

Lostmarbles is that a Toyota EPC you displayed my info does not show the B as using the same number as the 2B the pics you show are a good comparison on how the OEM and aftermarket are so different in construction.
I wonder why the OEM has so much more metal on the one side of the cylinder I am wondering if that has to do with the pre-cups.

RedHeadedStepChild you say it boils over try removing the rad cap then starting the engine look into the spout and see if you can see tiny bubbles rising up....if in fact it is a gasket leak this would cause pressure in the system and with the cap installed it would act just like the engine over heating since the combustion pressure build up will force itself out the over flow.

Yep... Home computer version of the epc...

I think Toyota went to town on the design of that head gasket to make sure it was the best possible.

It is of such recent design that I can find no information on the part number (11115-56120) as to which models it was designed to fit. (My information is all too old since I dwell in the pre-1990 era pretty much.)

But Web-based EPC data on this 11115-56120 gasket seems to be equally limited from what I see in my searches (with the part number not being recognised).

And BTW, when I search EPC data on the Web for 11115-56020 I get interesting information indeed...



This suggest it fits engines from 1977 through to 1986! But then it sort of destroys it's credibility by saying this head gasket even fits an HJ47 (as you can see above) How can it fit a 6 cylinder engine by any stretch of the imagination???



PS. I'm aware that when posting in the past I've said I thought 11115-56120 should fit this 2B engine (and therefore would supersede 11115-56020/21). And I still suspect this could be the case. But I'm not certain...

 

[RedHeadedStepChild]

Looks like Dave at Japan4x4 has one. So I'll be ordering that up. Thanks a million guys.

One more question; Dave has the HG, but not the rest of the gasket kit for doing a top end. I think a standard B kit will work for all the other gaskets required, but would like to call on your expertise.

When I get the gasket from Dave, I'll post up the pics for comparison along with the P/N.

So I take it that Dave is getting you 11115-56021...

August 1980 was a time of big changes for B-series engines so I suspect this could be the time the head gasket changed too (and that 11115-56120 may work only till July 1980 for B and 2B engines) (And my EPC printout in post #15 above supports this conjecture.)

The bores in B and 2B engines are the same but the 3B has a larger bore and therefore should always need a different gasket IMO.

And I think the existance or absence of cylinder liners affects head gasket design. But while I recently thought I knew exactly when liners disappeared from our engines my latest information-searches reveal liners still in use in some B-series engines right into the 1990's (So unfortunately I've recently been talking sh#t in quite a few threads on that topic!!!!)

It'll certainly be interesting to compare 56021 with 56120 (assuming 56021 is what Dave's getting you).

I still have an unused 11115-56120 here available for any measurement/photo comparison work.

And because I'm losing confidence in so much of what I thought I knew ... I'm now too scared to make any comment about whether I think a B-engine gasket kit (for the same estimated Nov 1980 build date) would work for you.

Second thoughts ..... Ignorance hasn't stopped me before so why should it now..

I say most of the kit should fit based on this (and the little fact that it's your money and not mine LOL):


If you can read the print on the label, the kit Engine Australia supplied me for my 1979 B is supposed to fit a 2B of the same production period so the same should hopefully apply to you.
