Thanks again to all that commented, I appreciate your input.

greetings, other than visual purposes (and making a good place for mice to nest), does the plastic engine cover serve a purpose, and more importantly, are there any potential issues to removing it & leaving it off?

Thanks again!

Thank you everyone for your input, excellent info!

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
