Hi Everybody,

I seem to be having trouble installing the overhead distributor base plate into the back of the overhead camshaft. The large green O-ring is showing, even after the 10 mm bolts have been tightened down. Is this O-ring supposed to be swallowed by the cavity on the back of the camshaft? Or is this O-ring just a press fit against the back of the camshaft?

When I removed the old distributor base plate (with Hall sensor), it was tight against the back of the valve cover. But the new distributor base plate (with Hall sensor) has a noticeable gap between it and the back of the valve cover. Tightening the 10 mm hold-down bolts doesn't seem to budge it much.

Any suggestions?

Thanks.
