Summary

I was sick and tired of either the oil change place spilling oil all over my valve cover or the dang funnel falling out of the hole and making a mess on my 2.2 liter gm engine used in lots of 4 cylinder gm cars in the early to late 2000,s. So i designed this funnel to fit in just like the oil cap does. i bought an oil cap from the local auto parts store for 2 reasons 1 to be able to design this thing and the other reason is i needed an o-ring the right size any way, you can source the o-ring on the internet but it costs more than just going to the parts store and buying a cap and stealing the o-ring off it and tossing the rest..
Happy printing !!!
