BTR Delphi LS7 lifter cleaning procedure 
 
When receiving your new LS7 lifters we recommend removing them from the packaging and checking for any obvious signs of damage to the lifter body or wheels. The lifters should then be washed in either an automotive solvent tank or with mineral spirits to help remove the stiff packing grease used during lifter assembly. We then recommend you check rollers for any binding or roughness before soaking.
 
WE  ALWAYS RECOMMEND THE USE OF NEW, FACTORY TYPE LIFTER TRAYS WHEN INSTALLING NEW LIFTERS!
