No, any hydraulic lash adjuster - not just the stock replacement type - will compress before it moves the valve. Lash is not lost lift. You calculate it, and account for it. but there is a certain amount of lift you cannot account for that the hydraulic lifter uses up to do it's job.
I'm not debating that hydraulics can't be made that are stable - A friend set records in Stock Eliminator trapping at 7800 with one in a Ford and there has been a ton of spintron work to figure things out. But he had to use some tricks to make the valve train stable regardless. Valvetrain component weight has very litle to do with the reasons a solid is better.
Do you also believe a roller lifter is better because there's a weight advantage?[/QUOTE No what I believe is valve train component weight is one of the most determining factors in valve train stability...do you think roller cams use such high spring pressures for no other reason than profile
