How To Remove and Replace Valves in a Cylinder Head

30 Jun

If you need to remove a valve from a cylinder head either to replace the valve or replace the valve seals, this video will help you do that. You can also do this process while the cylinder head is still fastened to the engine block with some tools. To do that, put the piston at TDC compression stroke and make sure both valves are closed. You can then run compressed air into the cylinder to hold the valves in place as you compress the valve springs.

I often use my compression tester hose to do this. You need to remove the schrader valve first before you attempt this, if not, air will not flow into the cylinder. You can also use a piece of rope or equivalent to keep the valves from dropping into the cylinder while you work. This method works well if you’re just replacing the valve seals. You won’t be able to use the large spring compressor however. You’ll have to use the Lisle or some other type of compressor do manage that task. Here’s some useful links for you.

Here are some tools I recommend for the job.

I had a heck of a time trying to find the Honda special tool and was not able to provide a link for you. Sorry about that. The Lisle tool will work just fine, OR I’ve seen some homemade versions of that type of extension that looked like they’d work pretty well.
