Toyota corona 1970-71 also on Hilux Toyota made these for Corona from 1964-1970.
The forklift engines usually are a little different
Considered industrial series however some were same as in cars ,may try at parts store to see if the parts will interchange

OK, I will be able to look through the old manuals in the morning, but I would have to see how I can get the manufacturer date.
It is probably too old to come up in the system.

This is indeed a 2R engine, but I don't see how that helps me unless all the 2R engines use the same parts. Looking up 2R engine parts on google gives almost no useful results (that is, useful to me). I can see a 2R overhaul kit for a forklift which could be correct, but also not useful to me.

My thinking is that, if I find a specific model year of car that would have this engine (based on the other numbers of the engine code, perhaps?), I can then find part numbers from an auto parts store, plus after-market stuff like a spin-on oil filter adapter, etc.

Is there a way to decode the rest of the engine number? Once again, it is 2R 1652405.

I've found a list of cars on wikipedia that have used (possibly) a 2R engine, but haven't had any luck with this specific engine and it's peripherals.

Thanks for your replies.

The engine type should be on the engine, either on the valve cover or on a flat area of the block near the distributor. 5R 4P.
If you don't get an answer, I will try to run it tomorrow and get a date for you.

Looks like 2-R by engine number google 2-R Toyota engine parts
