390 Dipstick Question

There is an oil leak coming from either the riveted square metal to the oil pan or where the dip stick enters the oil pan.

The PO had a wad of silicone around the dip stick base and took forever to get it clean, there is still a tiny residual amount at the base of the dip stick that's hard to get. I cleaned the whole area and waited a few hours for it to leak and it didn't. IMO, it doesn't appear to be leaking around the square riveted plate but at the base of the dip stick.

Does the dip stick just pull out or unscrew out. Right now it's being held by a bracket mounted to the exhaust manifold.

If I get the dip stick out, how best to put it back in and seal it?

Thank You!

Mine is attached via the front lower exhaust manifold bolt. Once that bolt is out it just pulls straight out. Might take some persuasion.

As far as sealing it back up I didn't use anything. Its a fairly tight fit and no leaks yet.

Thank you for confirming that it pulls out. Mine must be worn.

Anyone know what can be used to make a tighter fit.

I would imagine a light coating of silicone around it sealing surface would probably do the trick.
