Cleaning your roller lifters can go a long way to saving money on a rebuilt Roller Engine.
First carefully remove the clips with a pick or small screw driver.
You can tap the internals out onto a steel or wooden table.
There may be a line of oil residue, that fights the piston and spring from coming out easily. Just be patient and tap repeatedly, but not so hard as to damage anything.
If you get maround a minute of taps, try using an air compressor and a quality air nozzle to force the piston and spring out, with a blast of air throught the lifter.
Unless there's a bad groove worn into the barrel, they will eventually come out, after you break the hydro-lock from the oil remaining inside the barrel.
Then polish everything with a green or blue scrubber pad.
You'll notice the ridge is now gone.
After re-assembly, the piston will have double the movement of a used lifter.
Look for compressed or broken springs.
Verify the wheel on the rollers has no slop or bearing wear.
More than .004"play, means the bushing or needles are shot.
The rusted or worn outer barrels should be discarded.
