Brent---the last people you want to ask about valve springs are the valve spring people----also----take that several hundred pound pressure, multiply it by the rocker ratio, and just imagine the load on the parts---rocker/shaft/stud/pushrod/lifter---and if roller lifter--the needle bearings in the roller(probably the highest stresses per unit of surface) and the side loading on the lifter boss/body if not directly on the nose of the cam-- |
I guess I may see it a little differently...
If a rocker arm, stud, pushrod, etc., can't hold a static load, then they won't hold the dynamic loads plus fatigue stress that they're under, know what I mean?
As for the springs, I agree with you wholeheartedly in terms of speaking to the spring guys looking for advice. However, spring steel should not lose its temper unless it's overheated. I've seen spring pressures take an initial dive, but that's just after they get their first shot of a heated load and settle in.
And that raises another good point....would there be any residual
oil supply on the valvetrain parts after sitting for months? You may wheel the engine over until the needle starts to move, but I'm pretty sure the lifters have not pumped up at that point, nor has oil gotten to the pushrods, rocker arms, etc.
Regardless, I don't see any negatives of a pre-oiler, unless it is just a pain in the booty to mount one under the hood.
Al, we all deserve to be pound foolish every once in awhile.
