My rockers are in great shape but the lifters are a solid rock and will not go down.
How are you trying to compress the lash adjusters? By hand?
You may using a soft grip vice to squeeze the oil out of them.
The lash adjusters have a check valve and a spring inside meant to hold oil pressure once they have been "pumped up." A vice can be used to squeeze the oil out.
So just because they seem to be rock solid doesn't necessarily mean they are bad.
In fact, with new lash adjusters its recommended to soak them in oil and manually work the plunger to get air out and oil in.
And can we please stop calling these things lifters? They don't lift anything.
They are hydraulic lash adjusters.
