For those of us with newer Toyota/Lexus you can often break the composite cap when doing an oil change. You can drop the cap
and the metal tube and spring fly out. I know....
What I didn't know was that the bypass valve is built into the cap. Per Car Care Nut. So, when you decide to replace your broken
cap, make sure you get the right one for your particular model. I would never buy an after market cap. And I would imagine any Toyota
Cap would screw on any Toyota model (?) but I'm figuring the by pass pressure may be different with different engines (?).
Sure hate to slowly ruin an engine with an improper by pass valve. I can't prove anything I am saying. Just trying to help. Get the
right cap for your car. You can easily go to Toyota Parts Deal.com or Lexus Parts Deal.com to make sure of your correct part number.
