How do you know how much the lifters are going to bleed down while you're checking the clearance with no oil pressure? If you have oil pressure, you're sure that the lifter is completely extended just as it will be when the engine is running. That's why people use checking springs. The checking springs are not as strong as the spring in the lifter so the lifters don't compress. What I'm saying is instead of using checking springs, why not just turn the oil pump.
