Hello ! Today I started my dozer and moved it . Ran in for like 15 minutes. Then parked it and came back about 3 hours later . I opened the hydraulic tank cap and a good amount of pressure came out . The hydraulic oil also did a gargling/bubbling noise when I opened the cap. The noise lasted for a couple seconds. What can be causing this ? Is it normal?
