Valve seals are cheap and easy to install. Don't even have to remove the head. gregjo1948
80% of the time a oil change will take care of most oil problems.
I have found that Marvel mystery oil works very good. Change the oil and add some to the oil. If it is bad valve seals it will not fix it but will help.
You'll need an air compressor and a fitting to screw into the spark plug hole.Remove spark plug and roll piston to the top(tdc) ready to fire. Put the air pressure into the cylinder to hold the valves closed while you remove the keepers, retainers, springs, and old seals. If you don't have a valve spring compressor, the springs are light enough to compress by hand using a box end wrench or what ever you have to press in the spring to remove the keepers.Once you've removed the keepers, take out the retainer and spring. The valve seal is just slide down over the valve guide and can now be pull off with pliers or screw driver. Install the new seal, pressing it down over the guide. Sometimes I use a socket to gently tap it into place. Now is the hard part, if you don't have a spring compressor. You need to install the spring, retainer, and keepers. You need to compress the spring with the retainer on it and install the tiny little keepers while holding down the spring. The keepers are wedge shaped slightly and must go in place with the thinner end toward the spring. gregjo1948
It is easy to replace the seal without removing the head. BUT I would remove the head and clean it up and replace the gasket.
Not saying you need a head gasket but it can not hurt.
Why would you remove the head and why would you chance reusing the the old head gasket???? I see no cause to"clean" the head and you should always replace a head gasket. There's a very good chance the used gasket won't hold compression and then you get to tear the head off again. gregjo1948
Putting a inline shut off valve does not fix it. It is just a Bandaid
Fix it right and replace the fuel solenoid if it is bad.
