Oil Leak with smoke

[utkayaker]

Thanks to both of you!

It idles smoothly but runs a bit rough if I pull the oil fill cap off.

One thing I didn't do either is check to see how much oil is left after it smoked and blew a good bit of oil. I am now wondering if I can't find the leak because there is not enough oil in the engine to "feed" a leaking spot.

I am really starting to suspect that it is the front right spark plug tube.

Can I run the engine without reconnecting the AOS? Should I go ahead and replace the AOS even though it is probably ok? (I just bought the car so I don't know how long this unit has been installed.)

THANKS!!!
