This article had a cleanup tag. Some cleanup has been done, but I have replaced the cleanup tag with the automotive-part stub template.
This is due to the fact that the article doesn't provide much information about the technical advances this type of engine have brought in the automotive world, but it's just a collection of data about its versions.
It would be nice to know:
And I'm sure the list could proceed further. - manu3d 18:16, 27 March 2006 (UTC)
This article has a {{ reqphoto}} template even though there is already a picture of a Toyota R engine on the page. If there are editors who feel strongly that it needs additional photos, can you clarify what photos are needed by adding an "of=" parameter to the reqphoto template? Thanks!

60.240.186.81 contends that the 12R was used in the Australian built Corona starting from 1969. I searched through a lot of reference material and the earliest date I can find for the 12R being used in the Corona is February 1971 in the RT81 sedan, the RT87 van/wagon and the RT91 hardtop. My reference material includes Toyota's Vehicle Identification Manual (covering 1964-1984 for all markets except Japan and America), Japanese parts catalogues, Japanese/Australian/US brochures, magazines articles and 'The Long Run' (history of Toyota in Australia). 'The Long Run' mentions a 1600 cc engine but that could easily match with the 1587 cc 4R or 1591 cc 7R, both of which were used in the 4#/5# Coronas in other countries. At that point, AMI did not have its own engine production line, so the 12R would have to be made in Japan. But no other market used the 12R, so this is also an unlikely scenario. The Gregories Scientific Publications 1971 Corona manual mentions the 12R in the library summary but I don't have a copy myself so I can't verify if that is the 4#/5# model or the RT81 model. I have listed every Corona model I know of here: [1] . It is now up to 60.240.186.81 to give some proof that the 12R was used in Australia in 1969. Cheers. Stepho ( talk) 22:55, 18 March 2010 (UTC)

Hi, I was chasing up some info on the 18R (i own several) and I noticed some details are missing here-
Hi, Stepho, it is a straight SOHC 113 Horse power 18R (not the C or G) with 163.1 kg/cm^2 compression (well it was a million KMs ago HA!) - I've been chasing up every 18R manual (man there are a lot of variations even just on the 18R manuals) I can find, and what I just found in one today makes me feel like an idiot - (except only one of all the various manuals even mentioned it so not so much an idiot I guess) on the side of the Dizzy is an "octane selector" knob, which apparently lets you set it from anywhere from 90 and up. Still cant find any decent detail on using the knob tho, such as the octane range (is it 90-95 like ford/holden A/B selectors, or 90-98 like others etc etc) other than a recommendation to wind it till the engine sounds funny and adjust up or down as appropriate.. (BTW the supra's i referred to earlier were the poverty spec 1970's or earlier Australian ones, or the cheapo (sub 2.6 litre NZ tax avoiding) ones, however I don't think they were straight R's more likely RT/RG dual carb or side draught setups, and are unlikely to have seen the light of day in any other countries - but this is all 2nd hand speculation - my notes on Hiace RV Van, Surf and Hilux Pickup are correct tho, I have a 1980 pickup 2wd model parked in my yard, I previously had a hiace van, and I considered buying a 2nd hand 4wd hilux/surf pickup, all 18R or 18RC :o) — Preceding unsigned comment added by 203.123.90.144 ( talk) 02:46, 2 January 2012 (UTC)
Yer my original posting was to point out the article lacked a few details, and lacked details on equivalent octane.. the rest got outta control! If you like you can remove all my subsequent TALK posts after my original pointing out the lacking info - i have updated my original comment to reflect your points on the Supra VS my comment. I would delete it all but I am not a big fan of random wiki deletions without all involved' permission. Preceding unsigned comment added by 203.123.90.144 ( talk) 4 January 2012 (UTC)
@"Designed for longitudinal use in such vehicles as the Celica and Hilux and in production from 1953 through 1995, use faded out as many of Toyota's mainstream models moved to front-wheel drive. OHC versions featured a chain-driven camshaft, mitigating the danger of internal damage from interference as in belt-driven engines."
It doesn't "mitigate" the problem of engine damage having a timing chain, merely it increases the service interval for replacement. In any case the chain tensioner has to be replaced at the same interval as a timing belt anyway. Given that the OHV versions also had a timing chain (I assume they didn't use a timing gear ?), I'm not sure how to change this sentence. Maybe it should be simply deleted. 203.39.81.92 ( talk) 01:32, 9 March 2012 (UTC)
out of curiosity of the timing chain subject the 5R engine has two main versions timing chain and timing gears and is rated 97 and 106hp. is this done in other OHV R engines such as the 3R, as little between the two versions of 5R engine are interchangeable and there dose not seem to be a timeline between applications. the sumps/oil pans are not interchangeable, nor are the heads or water pumps and replacement gasket kits contain both styles of gaskets. personally the easiest way i have found to tell the difference between them quickly is to feel the PCV under the exhaust manifold, something that can be done without even seeing the engine and if where the PCV enters the crank casing if it bolts on it is timing chain, if no bolts are found and presses in like a core plug it is timing gear. which engine is the 97hp and which one is the 106hp version?

my 1969 RU12 dyna had a factory timing chain and i have a timing gear version out of an alleged 83 coaster (a so called 109hp square inlet and exhaust port version). yet while searching for a head for a timing chain version i was told that they were random and how i figured the easiest way to tell the difference was with the dyna, it was to kneel down and feel the PCV from underneath and they are random from my experience. oh as well the owners manual out of my RU12 said there was a J 2.2l diesel option, the only other place i have seen an engine that looked like it was in a 1960 toyopet stout that was for sale from chile...

I have a 1986 Toyota Corona (Australian production) with this engine, which is not listed here. The model was designated "Avante" for the manual and undesignated for the automatic with "Super Responsive" decals on the exterior and in the engine bay. The standard model used a 2.0L engine. The same year the front wheel drive Camry was released with a different engine. 203.39.81.92 ( talk) 01:42, 20 March 2014 (UTC)
