Hello....

The cap / dipstick on my 4K Onan has become pretty loose.

I'm thinking about replacing its rubber stopper with a new rubber plug.

Will this new "tighter" seal cause problems elsewhere ?? Might the oil fill tube also provide crankcase venting ??

As always, thank you all for the wealth of information provided here.

Steve,
They all get loose, but it should not effect the operation unless the
engine is worn out.
