I was wondering what kind of lifters are in my 85' 4 cyl.

And what way you would recommend for me to adjust the valves.

Running or not?

Tools?

Nothing.... Really?

Hydraulic lifters and the rockers are not adjustable.

I thought that you could adjust the valves by tightening or loosening the nut on the top of the Valve.

Is a valve also known as a rocker?

SeriousOffroad

No.
Lifters ride on the cam, pushrods ride on the lifters and push up on the rockerarms, the rocker arms pivot on a fullcrum, the rocker arm in turn pushes down on a intake or exhaust valve. The valve is returned to its closed positon by way of a valve spring.

None of the these components are adjustable on a 4.0L motor.

He has a 2.5,however it does not make any difference,they are also hyd lifters and the same applies.

Ok. Thanks anyways guys.
Figured that it might be a way to fix a tick sound that I thought was a loose valve.

Thanks,

Your tick is coming from a worn out lifter.........nothing you can do other than try a thicker oil....Our rockers are "Pedestal" mount rockers....they are bolted down to 18-20 ftlb at the factory No guess work.(they can be adjusted with shims however a stock Motor wont have to worry about this) the adjustability you are refering to is "Stud" mount rockers....they can be adjusted with the engine running but that is a old school method the chevy guys use to use...and its messy
