Burner112 Posted December 25, 2024 Report Share Posted December 25, 2024 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. Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted December 25, 2024 Report Share Posted December 25, 2024 Not a drain vent, is it at the bottom? Pressure equaliser for boost in the inlet versus vacuum in throttle body? Although there should be a one-way valve for that, you don't want your turbo pushing into the crankcase. We run them on the turbo rally car but it just goes from tappet cover (two big hoses) and out to atmosphere. http://mcnallycatchcan.com/ They go to inlet and to airbox, so both sides of the throttle body. Is it like that? Quote Link to comment Share on other sites More sharing options...
