Hi,
I own a 2001 Corolla Sportivo factory turbo. I bought it off marketplace and found that the previous owner of it had installed an aftermarket catch can system. The car also made a loud whistling noise on startup. Suspecting a PCV valve issue, i replaced the valve and also reinstalled the toyota factory catch can and this fixed the issue. However, I'm not sure how it is meant to be connected and if these cars came with a different pcv valve to the non turbo versions. There is a third small hole in the catch can and from pictures of other peoples engine bay it appears as though a hose should be connected to this going somewhere, but I'm not sure where. Any info or pictures of the stock pcv system for these cars would be greatly appreciated.
Cheers.
