New lifters

[Ottomotion]

Went to install the new lifters today. Brand new INA units. I could not depress them at all. My old used units could easily be 'plungered' with slight firm finger pressure.
Can I assume the new units are full of oil from the manufacturer and do no require pumping up on the bench?

Thanks

Hey,
How long had your car been sitting before the tear down? In mine, that sat 11 years, some lifters were stiff, some weren`t. I think the ones that could easily be plungered were the ones that belonged to the open valves, as a result they lost the oil over the years. I don`t think they are necessarily bad, they were just under pressure for long and just released consequently.

My car sat just a few weeks. I was actually able to drive it into the shop bay, so the lifters were all operating normally just a few days before tear down...
