lifters how to tell what I got

[Joe Ricard]

Should be an easy question but want to make sure. the engine is a 70 1.7L with the FI. Is there a way to identify hydraulic or solid without pulling the valve train apart?

Should I see no lash and be able to compress the rocker arm against the lifter? or have .006 lash and no compression of lifter.

If you have a tapered steel pushrod, negative lash and rocker spacers with 2 wavy spring washers instead of a single longer spring between the rockers- its hydro...

If its solid it'll have aluminum pushrods.

Chromolly pushrods and the rocker spacers are also sometimes sold as "upgrades" to solid-lifter motors. So they are not an absolute proof--but they are strong indicators. The only way to be completely certain is to pull out the lifters and check them.

However, with 0.006" of valve lash I think it's safe to say they're solid lifters--particularly if they do have the spring between the rocker arms and the fatter aluminum pushrods.

cool sounds easy enough. Just came to mind when SILVER had to abort his trip because of the valves getting tight.
