go to pep boys. they have a valve spring compressor that has a handle, or for under the cowl it comes with a bolt that replaces the handle you use a ratchet on. that is the only only one that works......well. its 25 bucks

 

Buy the $130 tool and sell it when you are done. It was a piece of cake with that tool and an air line hooked to a compression guage line with the schrader vlave removed. I am keeping the tool as I will probably do more in the future...
