Description
This little tool will let you change out valve springs and valve seals without removing the head. It's a great way to deal with a set of leaky seals, for example. Oil smoke on idle and overrun? Easy fix.
How about a new set of valve springs? Now you can swap those out without pulling the head off as well.
It's designed specifically for the NA/NB Miata and bolts on to the head. The valve is held open by a screw so you have both hands to work.
You will need to prevent the valve from falling out of the head. You can use a leakdown tester to provide air pressure in the cylinder or you can feed rope down the spark plug hole so it piles up on the piston and supports the valve.
Please note that the valve keepers can get bonded to the valve spring seat, meaning that things won't come apart as intended if you simply compress the spring. As long as you follow the included instructions, you'll be fine.
Fits all NA and NB Miatas as well as many other twin-cam engines.

Worth every penny- this tool is fantastic for removing valves.
Just finished using this tool. It worked extremely well and is worth the price. There were times I had to walk away because of the keepers and due to the design everythIng stayed in place while I took a breather.
Product worked swimmingly. This tool turned a 12 hour just into a 2 hour job. Highly recommend
This worked without a hitch. I used this with rope (car passion channel) in the cylinders in order to keep the valves from falling into the cylinder. One piece of advice is to use ceran wrap over the base of the compressor to get the valve keepers to stay in the retainer as you push the compressor down 3/4 of the way.
Just used this tool for replacing valve stem seals and would definitely recommend. Worth the purchase 100%
