I’m trying to replace the breather hose on my 2005 Toyota Camry (2AZ-FE engine). It seems to be a special part? I measured it with a caliper and it seems that the inner diameter on the thing It’s connected to is exactly 16 mm, with a lip of 17 mm. Meaning I think 5/8 inch (or 10/16 of a inch), which is 15.875 mm hose as a replacement would be to small? 11/16 inch, which is 17.4625 mm would be to big? Maybe I measured it wrong with my caliper or my caliper is slightly off? But I can’t find the specified measurements on the original breather hose online anywhere. Any help would be appreciated. I hope just to use generic PCV hose as a replacement, instead of buying a OEM replacement, which I’m not sure would even be in stock on such a old car. Note I’m specifically looking for the breather hose of the PCV system, not the PCV hose. ---

Why beat your brains out when you can just take the hose to a parts store and see if they can match it . If you only have one vehicle maybe a friend can take you there . ---

Rubber hose. Rubber stretches. Use the 5/8ths emission hose generically available at the parts store. Add a little soap on the nipple to make it easier to slip on. Install the hose. Have a beer. Stop over-thinking this stuff. It isn’t rocket science.
