Greetings, could someone tell me approximately how many oil return passages there are in a 1zz-fe and where they're located? I'll attempt to attach a representative photo.

Thanks & take care

I would say, look at the 3 brown passages on this block, just those and the cam chain passage.



then match up with a cylinder head pic, I think I see 3 next to the head bolts at top of pic

http://www.corollaforum.com/threads/how ... down.6726/ has a pic of the underside of the head that came off that block

I don't know how /what oil returns there are from the top of the head that drain into the chain area

edit I also attached a PDF from the 03 matrix manual about the 1ZZ lubrication system, has a couple of interesting pictures



Just curious, what circumstance prompted the question?

just behind the sprockets would fill fill oil if there weren't a drain, so I'm pretty sure there is one.

Light looks to be coming through a possible opening in this pic:

Thank you everyone for your input, excellent info!
