LSM valve spring tester

[Jesse Knapp]

I don't remember the shim amount off hand, been 3.5 yrs. since I sold the engine, but I have a note book somewhere with everything logged. I will find it and post the shim amounts. I had LSM's removal tool as well and never had any problems with it. Just off my head I'd say the stands are not shimmed up high enough. Is this a Jesel system? If so, a checker tool should come with the purchase of their product. Unscrew the part that sits directly on the spring retainer all the way up to allow complete clearance. Maybe their is some machining defect (bolt to shaft allignment) or maybe you have the wrong puller for your application. Who's system are you using? I wouldn't alter the tool, but I would call LSM and talk to them. I am not an expert but I did enjoy working on my stuff. I had never done any work with springs on any of my bracket engines. I had always brought the heads or the car to someone else but when I went to superstock, I became fascinated with valvetrains. So I talked to a superstocker friend and a stocker friend the does heads for a living and started maintaining my own stuff. Also worried my head off about springs and lifter life. Having said that, I am not a pro, but I will tell you what I do know, if it will help you.
