P80 Master O-ring Model Part Number Size Type Comment Thread

Post by abscate »

You know the scenario - you are working on the car, then suddenly and O-ring is broken
Our great vendors have these parts, but you need to be back on the road now, and $20 shipping on a 0.29 cent part seems rough.

Goal - as we do our DIY jobs, document the size of Orings so we can find the right one locally and get out of a jam.

When you buy O-rings, buy 2 extra. You’ll figure out why

1999 CVVT O-ring sizes on Intake Cam 9440651

Post by abscate »

Measured on an 1999 Intake Cam


Outer Cap Oring 28mm x 1.5mm

Inner VVT hub Oring 50mm x 1.5mm

See screen shots for part numbers - it looks like I was measuring a part 9440651

On edit...I think these are the cam seals , not the CVVT Orings
