An internal leak is caused by a damaged seal
inside the hydraulic cylinder. Because the
cylinder is leaking oil inside (bypassing), a
certain amount of pressure is lost reducing
the cylinder efficiency and its capacity to
push or pull.
If the packer cylinders are bypassing, the
seal inside the cylinder may require to be
replaced. If an internal leak is suspected,
apply the following procedure to verify it:
