Engine Identification

[bsevans]

Can any one tell me what these markings represent. This is on an engine that came out of an 87 FJ60. The serial number block is only stamped 2F. The manifold side of the head has an addition half dozen or so smaller tapped holes that are not used by the intake/exhaust manifold I pulled off.

Additional photos.

and more photos. The photo of the bolt pattern on the head was taken with my cell phone and is not the best quality. The valve cover nuts were barely hand tight, which lead to quite a bit of oil leakage from the cover. Comparing the threaded holes to the drawing on page 44 in the Spector catalog, it appears that this head has the 3FE manifold bolt configuration. Was this normal on late model '87 2F engines?

Not Original 2F

bsevens,
I bought a brand new 2F for my '84 FJ40 from a Toyota dealer late 2008.
It has the same casting numbers and had only 2F stamped as yours.
I'd say it's not the original engine, but a engine to replace the original.
From the casting number, it's one of the latest trims / changes made - I compared it to my original 2F casting number and other late model 40 casting numbers.

cheers

Thank you for the reply. Did you buy the block by itself or a block and head assembly?

I got a "short block".
Block with crank, pistons & cam bearings installed.
Other than that - nothing - not even a dip stick tube!
cheers

This is the date code:

1 11 13 is in the Y MM DD format. So it is a 1981/91/01 november 13th casting.

The year can be narrowed down by looking at the plug in the front oil galley (below the PS mounting). If it is a welch plug, the engine is 84-earlier. If it is an allen head pipe plug, the block is 85-later.

It has a 3F head, which became world standard in late '84.

There is no serial number, so the block is a dealer replacement, not a complete factory engine.

*edit* Misunderstood what was being asked.

 

[FJ40Jim]

He's talking about the extra 3F manifold bolt holes, not the AIR holes.

Search for a pic of 84-earlier head to see the difference.

The front oil galley plug is an allen pipe plug. I'm assuming from what you said that this is a 1991 or 2001 casting. I would tend to believe that it is a 2001 casting given how new the freeze plugs look and the components attached to the engine. I appreciate your sharing your knowledge on this topic. Again thank you very much.
I bought the complete engine from Tim Hill. Bell housing to fan and all the components that were attached had no bearing noise.
As I disassembled the components off the engine, I was struck by how new most of the items appear. The water pump and fan clutch look new. The intake and exhaust manifold assembly came off easily and have no warp on the assembly surfaces at all.
This came out of a very strong running LandCruiser with high oil pressure that impressed from idle to highway. The flywheel and pressure plate have only a couple of minor hot spots and no cracks. The clutch has minimal wear. Both the sealed pilot bearing and the throw out bearing are smooth and noise free. The clutch fork has minimal wear on the pressure points. Everything worked noise free - A/C compressor, alternator, power steering pump, smog pump and dizzy. The bell housing marked 3F has no ears for frame support so I bought a HD transfer case nose cone support that I will install when I make the change over.

You aware of the infamous head problems associated with the later 2Fs?

Head Problems

Probably the reason the engine was discarded

No, but it ran so strongly. Please expand and educate me. And by later 2Fs, exactly which years are you refering to.

Hopefully I can sell the dizzy and intake/exhaust manifold assembly and not take a bath on my poor choice of engines to invest in. Of course, I may have to sell the carb, A/C compressor and power steering pump also, if I've underestimated the component values.

The only "problem" w/81-later cylinder heads is they are 15 pounds lighter than earlier castings. The reduction in material thickness around the chamber means they crack easier when overheated.

Don't cook the head and it will live forever.

Again, thank you for the insight and information.

bolt hole

Can anyone tell me what this bolt hole next to the oil galley plug is for (between 10 and 11 o’clock to the oil galley plug)? I tried to run a 10mm x 1.0 pitch tap into it but no go. It does accept a 9mm x 1.0 pitch tap. Either the lead-in threads are buggered or it really is a 9mm bolt hole. It was not used by either the power steering pump or smog pump.

Yep, that is the bolt directly to the right of the water pump....
