Anyone know how to make the thing that you screw into the spark plug hole and connect to an air compressor, the tool used to prevent from dropping a valve when replacing valve springs?

It looks easy to make, i just dont have one to get my hands on, well if i did i guess i wouldnt be making one lol.

Thanks, Im sure others would be interested in this as well!

 

Just use a leak down tester in the spark plug hole, but let the piston roll to bdc not tdc. Make sure your rockers are off first and you are good to go. If you don't have a leak down tester use a compression tester hose without shrader valve, and hose clamp to a normal air line. Hope this helps.

 

all you would need is a threaded fitting that matches the threads in the plug hole, some hose, a couple of clamps, and a shrader valve on the other end, and you could make your own. like he said, just take the rockers off first, and your good to go? seems like it would work......

 

napa sells a fitting that goes from spark plug thread to female 1/4 npt for your air fittings

comes in 2 sizes 14mm and 18mm in 1 pack

usually located on the tool tree part number SER 901
