So theres no lash adjustment needed? I guess because the valvetrain is so short.

There's nothing you can adjust on the bates lifters, once cut thats the lash, these heads cannot be shimmed

Ask John about his harley davidson pushrod haha

Well that's good to know. I've been waiting to build a head until this whole solid cam set up was finalized and working right. I was never happy reading the results from the hyd cams out now. Good to see you guys getting it all done.

You said in the original post, all lifter generations. Have you seen the newest ones that are also used in the HFV6 and the newest Ecotec's? They cannot be disassembled it appears, and the tip is necked down (I can post pictures if needed). I suppose they are having the same problems as well? If it is strictly on lifter size, then I could see that. It seems like the head could be machined to accept a larger lifter if need be (like the Honda lifter if it is better). I cannot see a lot of people going solid due to cost. What about long term wear issues also? Not trying to hate, the information given is great. I am just trying to approach it from a practical angle of keeping the hydraulic setup and optimizing it as much as possible. Will continue to follow this thread and maybe get a junk Ecotec head to do some testing on.

Has nothing to do with hydraulic lifter length, it has to do with them collapse under high cylinder pressure and lift

/\ /\ On possibly a related note;
I recently was told that the OEM lifter part number has been superseded - maybe this new design lifter is to be used on them all?

I was talking diameter, not length. More surface area against the oil, less susceptible to collapsing.

I will post pics too, you also want gut pictures?

The part number I have is the same lifter that fits the LF3, LTG, etc. The old style has a crimp ring, this new style must have an internal snap ring.

Here are pictures of the latest generation lifters (gen 4?)





If you look closely you can see the oil feed hole is positioned slightly higher and is a tad bigger, while the relief/follower oil feed hole is definitely smaller. You can also see the necked down portion I described earlier. Can cut it open if it's wanted.

It seems to be the same length as the others but I can measure it with a caliper gauge tomorrow if you want.

Why dont ecotecs perform better with cams

stupid question that shows my level of understanding
what would it take to run a larger lifter like that?
completely custom machined head and matching valvetrain?

Do you know how big the Nissan lifters are for the SR20det?
