Replace the valves guide seals.
Need more info. It can be $5 for a Tire valves to $2000 from bent valves/damaged pistons.
I would use a tap and die set to re-thread the shaft down one size.Since it's just a hold-down nut, it won't affect the functionality.
around 900$
You can get a heart valve surgery to fix that. You can also avoid eating oily food that can clog up the valves. By not doing so, you are at risk of heart attacks.
Add a little white wine and make fondue!
Take the head off and replace BOTH valves.
Block, crank, pistons, and valves. Those are the main parts that cost the most to fix.
you need to have the timing belt replaced....if it has broken you have probably bent the valves
If the valves are ticking they are likely damaged. If what you hear is lifter tap, then it is due to poor design from the factory or you need an oil change. Lifters from a 3g Eclipse (00+) fix this problem.
You have to pull the heads so the seat can be resurfaced and valves only come out from bottom most engines.
