1966 FJ40 help needed

[Cee Jay]

If the number stamped on your block matches your VIN plate you've got the correct block.

I have no Engine number stamped on the serial plate, just a frame number. Are you saying that my engine should be stamped with the same number as the frame number??? I was told, by I have no idea at this point (input overload), that those numbers are not supposed to match.

Just a note, I do have the "original" carb and adapter plate, so I'm good there. It came with the FJ. I also have gathered the correct oil bath and air filter setup. I am gonna send the carb to Mark to have him rebuild it.

Oh yeah, you might want to check the red breather hose on the valve cover. That is supposed to go to the air cleaner and allow clean air into the motor. It looks like it's diving down to the road, not much clean air down there. That, and two PCV valves in series are typical carb swap idiocy.......

Uhhhh, that is gone already. I think the PO was trying to get the vapors to exit by the tires instead of in the cab. I just LOOOVVVEEE backwoods engineering.

I am also trying to figure out where the adapter plate small nipple (marked "n" in the diagram) is supposed to go. Mark A said prolly emissions, so cap it off. Am I really the only one with this setup?? Why is the year after so different?

Another crazy note: I may be looking at a "new" 1968 tonight or manana. I'm not obsessed, I just cant get enough.

You probably have an engine number stamped on that flat spot on the block near the distributor. There is a table (like the frame number table) at SOR that may give you an estimate of the month/year the engine was manufactured. Then you can tell what's up. It's possible your engine is a replacement engine, too.

No, it won't be the same as your frame number, but you can get an idea about whether the frame and engine are a match.

I was mistaken. Thought that you had a motor number on your VIN plate. Without the VIN plate with the motor number, there is no way to tell if it is the exact motor that came in it originally. Like IDave said, you can only get an idea if the motor number is in the right range.

Thanks again. The engine number is "F 266687", if anyone can tell anything from that. I am just gonna pretend it is original until im shown otherwise.

WISH ME LUCK ON LOOKING AT/BUYING THE "NEW" FJ40 LATER TODAY!

I am surprised that a '67 would have the early style intake. Isn't 1967 when they finally figured out the aluminum intake manifold and switched to the screw on filter that bolted to the "3" holes in the side of the manifold???

They changed to the aluminum intake in 67 but towards the end of the year with the start of the 68 model. That was part of the change from the F135 to the F145. The 68 model and the early part of the 69 model had a one barrel carb on a two barrel intake.

The F135 started sometime during 1960 during the last year of the FJ25. The F145 started with the 68 year model and ended with the 71 model year. Then then the F155 went from the 72 model thru the 74 model Easy way to tell these is the oil fill is in the valve cover and it's still stamped steel. The 74 had the later 2F oiling system. Many call it a F1 1/2 but I've never seen Toyota call it anything other then a F155.

The spin on oil filter started in 1969.

While oil bath cleaner air cleaners were common in the early years they were still an option. The paper element was standard even though most seem to have been oil bath.

The engine number stamped on the VIN plate seemed to have ended in 1965. If my FJ45 would of had the original F engine that's stamped on the VIN plate I probably would try to keep it stock but since it has a 75/76 2F I not.

If that is so, why does the 67 parts maual, that probably went into print in 1966, list it??? Were they just letting us know what was to come in the next few years???

I'm not trying to be a pain in the butt, I just love the research and history.

 

[Cee Jay]

Just out of curiosity, what was the displacement of the F145?? My serial tag shows an "F" with a displacement of 237 ci. Is that an F135, F145, or what?

they must have swapped a newer style head onto the block it should have siamese ports being a 66 and if all was original.

I am conceding that it is an engine (or at least a head and intake, etc) from a year or so later. I dont really care so much now, because I just bought an original 1967 FJ40 last night that is in amazing shape. I have redemption! I will create a separate post for it. Thanks for everyone's help. I may be getting rid of the '66 if anyone is interested, just PM me and I will give you the details.
