Intake manifold o ring By kamchatka (Read 483 times)

Hi chums,

Wanted to put a new intake manifold o-ring on as part of ongoing rebuild; the old one doesn't look too great. More complicated than expected. The "GY6 complete gasket set" I bought on ebay has an o-ring ostensibly for this purpose. But as I try to show in the pictures, it doesn't match what I had before. Everything on the engine is stock. I can stuff it in the groove on the manifold but a whole lot of material is sticking out.

Maybe this is intended? Does the o ring compress? Thinking back to school, remembering a 2000 page "handbook" about O-ring manufacture and installation, thinking these are some deceptively complicated little suckers.

If not, any ideas for how to go about getting the right part? Have not been able to find anyone selling just the o-ring online.

They squish down when you tighten the Intake manifold up. Notice the old one side ways how it is flatten out.
