Was about to start a new post but I might as well revive an old thread.
So I saw in the tech files this video:

Is the adaptor that they use for the ford glow plugs come with all compression testers, or is there a specific diesel compression tester? Can I trust a Harbor freight tester, or should I buy one at a parts store like Oreilly?
Also, what is the easiest way to disable the injection to keep the motor from firing? I am going to be pulling the injectors anyways, so should I just unplug the UVC harnesses or unplug something else to kill the injectors or PCM to compression test?
I am planning on testing my compression while I am under the valve covers next week putting in my Stage 2s from DIY, and will be changing the glow plugs while I am at it, might as well see how this 240,000 mile motor is holding up.
I dont have any issues, not burning or leaking any oil, besides now an HPOP line, so I should add that to the list of things to change. So I am pretty confident that the motor will be good, just want to verfiy, like the fact that I know my model year is a forged rod block but I pulled the plug today just to take a look and smile knowing I have decent rods.
Also while I am ranting, what specficially is the contribution test? Correct me if I am wrong its testing the injector intensity through the OBDII port? If thats the case and I am putting in reman injectors I should have to bother with testing this, they should all be good?
