I took off my distributor out the other day while I was swapping intakes. When I got it back in and bolted up I noticed the cap was crooked, one side was about an 1/8 of an inch higher. I checked the square slot and everything was lined up, but the vacuum advance bracket was keeping the cap from coming down all of the way.

I thought this was odd because the bracket is installed correctly and the spacing of the vacuum advance "bracket" seems correct.

The cap is one I grabbed from the parts store. Is there a chance the repop's "come down" on the distributor base more than the factory ones?

More importantly, would this affect anything? It seems to run fine the way it is.

If it is touching the vacuum advance arm it could affect the vacuum advance that your engine sees.

It shouldn't be like that. Get another cap and start checking. It should sit flush on the round upper face of the distributor body, not be held in mid-air by some interference point.

Hah, well I figured it out. Ends up the vacuum arm wasn't interfering with the cap, they were just really close together.

So i took a look at the intake I had on there before and wouldn't you know, the hole for the distrubtor to go into is on an angle, so naturally it sits a little slanted. I always thought they sat flat on the intake surface. Lesson learned.
