Talk:Toyota Y engine

what is the proper air fuel mixture for a 4y lpg motor

not convinced that info on 3Y-C is correct - I have (for the time being, shortly to be scrapped) a 1986 Tarago with a 3Y-C engine, and I'm 99.9% sure it has no catalyst. - 139.80.40.239 (talk) 04:37, 8 September 2015 (UTC)

3-YEC not listed
This article is missing data for the 3-YEC / 4-YEC engines used in the US Toyota van from 1984-1989. Although similar in design it is not the Lite Ace sold in the oriental market. In my humble opinion the 3-YEC was one of the best engines produced by Toyota, after driving over 250K miles in my 1985 van it was as strong as ever with no oil leaks or repairs beyond a water pump and two clutch disks.

 * Are you sure you have remembered the code correctly? The 'E' means EFI and 'C' means carburettor with Californian emissions controls. These cannot be on the same engine. Possible contenders are the 3Y-C, 3Y-E or 4Y-E. Outside N.America, your vehicle was known as the TownAce, MasterAce, Tarago, Space Wagon, Model F or Space Cruiser. See Toyota_LiteAce. The LiteAce was a slightly smaller relative of the TownAce.  Stepho  talk 23:25, 4 June 2023 (UTC)


 * Nope, it was not any of those. As I said it was similar to those but not the same. You can find pictures of the US version here: https://constantcompass.com/2019/01/24/why-i-chose-a-toyota-van-for-my-camper-van/
 * As you can see the headlights and parking lights are different to those of the LiteAce or any of the other variations and the windshield is not as rounded too to bottom. I know for a fact the engine data plate read 3YEC and that was replaced in 1986 by the 4YEC. TainoNC (talk) 15:10, 5 June 2023 (UTC)

 * Looking at those images, I see a Tarago (I'm Australian) with slightly different front lights. You will also notice that the front lights are on a separate piece of trim. Car companies often have what are called "hanging panels" that are separate from the main frame of the body. They can be customised for particular countries or changed for a new model year to give a quick and cheap way to give it a different look.
 * Considering that the codes you remember contradict the normal pattern of Toyota engine codes, we will need some proof of these codes. Can you point to images of vehicle build plates with those codes on them or something else official? See WP:FACT and WP:RS for why we need this supporting evidence.
