I just replace the intake manifold gasket (lower) and putting it all back togethor, I marked the distributor on the base and on the intake before I removed it. Now it won't seat all the way in.
Do you
have the same problem?

Turn the rotor back one tooth and try and as it setting it should get where it should and if not
you can get it as close as possible to your mark and then set the cam
this is how to do it
Adjusting Camshaft Retard Offset
Turn ignition off. Slightly loosen distributor hold-down bolt. Start engine. Increase engine speed to more than 1000 RPM.
Using scan tool, monitor Cam Retard Offset. To adjust for a negative reading, rotate distributor counterclockwise. To adjust for a positive reading, rotate distributor clockwise.
Continue to adjust as necessary until zero degrees plus or minus 2 degrees is attained. Turn ignition off. Tighten distributor hold-down bolt to 25 ft. Lbs. (34 N.M). Start engine. Increase engine speed to more than 1000 RPM. Using scan tool, verify camshaft retard offset adjustment
