How to Remove Valve Springs (Overhead Valve Removal Tool) • Cars Simplified

This episode of Cars Simplified: Season Three reveals how to remove valve springs with a "Universal" Overhead Valve Removal Tool (Autocraft AC521 is shown in the video, but other companies make the tool as well) and different techniques that can be used, including a fast and aggressive approach.

The tool shown in the video is designed to grab on to and compress the valve spring, so that the keepers can be removed. Once the keepers are out of the way, the spring and retainer can be pulled out of the way, and the valve is free to be pulled out.

The head must be off the block to perform this properly.

Steve just used the neodymium magnet he had laying around, but you can buy one that works better for your tool.

Ending: Brumby on a road trip! Zen mode.

Videos like this is what I'm looking for. Simple, clear and easy. Thank a lot!

Great video. Just wanted to add that this is the best tool to use in tight spaces, such as when the head is still on the engine. His techniques will be the same, except you'll need compressed air blown down the spark plug hole to keep the valve in place. Also, make sure your cam is in the correct position.

I brought this tool today, so I could replace my valve seals. I got one off without no problem. But the second one, gave me drama. I tried to find something to place under the valve, so it could stay in place. I have to find something soft & sturdy, go up under there. So, will try again tomorrow.
