Re: help, dropped nut into intake
Maybe the nut could be sitting on top of an intake valve, or between a partially open valve and seat. Will be interesting to learn what you discover.
If you use a vacuum cleaner to draw on the intake port, be sure to install a spark plug so you can create a vacuum, not just air flow. Or tape off the intake port if you draw on the spark plug hole. Even then, it may not be possible to create much of a vacuum if the exhaust valve is even barely open. I guess you could always back off the exhaust rocker nut a turn or two to make sure.
And be sure to empty the dirt out of the vacuum cleaner first, so you can confirm whether or not the nut got sucked in!
