noob question (now that swap is done)

This may make me sound really dumb....but, now that I have my LQ4 successfully running I had to change the oil since it had been missfiring due to the harness being made wrong (cylinders 6 and 8 where wired wrong among other things....I thought that the oil "spout" cap would just twist off so I could pour the oil in ...instead it appears the whole spout comes off with a 1/2 twist and the top cap on the spout just turns some but does not come off?

Is this right and if so why the "spout" rather than simply a cap?

Does this make sense? I would have thought the "spout would make pouring the oil in easier.

Thanks

sounds like the oil cap is broken.

mine is tough to get off, the cap part that is

but the whole "spout" does not come off on mine....

Thanks guys just went back out there and got the cap off and eliminated the "spout" I needed the room anyway!

You guys are awesome.
