Kubota L35 Problem

[Russell King]

That is what I would say is “BAD”!

Can you even see the valve stem that is supposed to be in that spring and holder?

Not sure exactly this little piece is sticking up it had a small like spring ring around it at the point it’s broken off.

Oh no, you're in for a shock when you pull the head.

My guess is your going to find a destroyed valve, piston, and sadly very possibly a destroyed head and even worse a destroyed block.

Best case ( really a reach) scenario, piston, head are gone and the block is salvageable
That block is not a sleeved block so it's not good if damage to the cylinder walls are present.

If you do get lucky and the cylinder is salvageable, you will need to take every single component out and clean everything to get all the metal out of it.

This might end up being a cheaper option:

That's the valve guide, and seal.
The valve is inside the engine, in a thousand smashed pieces!

Yes I read back through the original posts and that valve is what caused the engine noise you complained about originally!

I assume that the valve spring was unable to keep the valve keeper tight and the keeper let go of the valve. The valve then fell onto the piston, and the piston and valve beat the snot out of each other.

As NIW says I hope the block didn’t get damaged!

Next step is to get the head off and see what damage has been done.

Good Luck.

Would there be metal pieces down in the oil pan?

Seems to be a lot of sludge in that engine, based on what the head looks like I imagine the oil pan is the same or worse. Time for a total tear down.
