I was asking about the Aluminum Toyota (Venza) not aftermarket. Has your research found problems experienced like the Toyota plastic version?From whatever I understood, the problem with aftermarket is that there is no warranty that bypass valve spring is able to maintain the same pressure as in oem housing. That could potentially allow oil by pass all the time or oil starvation if the spring is too strong.
Aluminum housing from Toyota should have been fine overall as long as the tube is the same length.
