I recently had to replace my 30 yr. analog old 1000 Lbs. bench valve spring tester with a new one from Summit, I ordered a Longacre and was told 4 to 8 week delivery and then 8 weeks later I was told it was being delay another 1 to 3 months so I order the Intercomp brand 1400 Lb. max pressure and got it in a couple of days, it is not what I expected, it is much less than what I wanted but it does work I had a dial indicator on the old one so I could get the valve springs compressed just like they are on the heads with the installed height accurate (using the retainer and keepers on the same valves that they would run on ) and end up knowing exactly how much it was from reaching coil bind at the open heights I wish I would have order another Longacre brand to compare the two but I haven't

The problem with on head testers we found is different people doing the same test got different results. I have a mate who has one, when seat pressures are low we can all get close readings, but I'm running high seat pressures for a roller & we can varie by 40 psi. I'm looking for a bench unit with positive stops so any of us knuckleheads get the same reading. Yep.......like I said , it took me a while to get a technique I was comfortable with that gave me consistent results. But using the same technique , whoever is pulling the handle , if you see a significant drop off in seat pressure , the spring comes out. I am around 250 on the seat , and if one pulled 10 % less , it would get my attention.

yep tubtar, doing the same thing everytime, even at different rebuilds is the problem. This is why i'm asking about the one in the OP. not having seen one I was hoping for some feedback, its available thru Summit so i can consolidate a few items to save on freight.I'm down under so if i shop wisely i get a few things at a reasonable rate. The one i'm looking at is compact & looks almost idiot proof & being consistant, data from 1 rebuild check to the next should be consistant. Really cant see that happening with an on engine tester. Gotcha. Usually , the expensive one is the right one. But after international shipping and the duty or tax , they are all expensive for you.

I lucked out and found this one on Moparts many years ago and love it. I also have a nice LSM on engine checker but I rarely ever use it.
