Vacuum Tester VC555 – Applications & Use Cases in Automotive Leakage Detection
The VC555 Vacuum Tester is a quick and reliable diagnostic tool designed for detecting leakage in engine components by simulating vacuum conditions. It is essential for engine rebuilding, quality control, and leak verification in automotive workshops and Assembly Line in OEM Auto Industry
Key Applications in Automotive Engine Work:
Valve Seat Leakage Testing
- Accurately checks for leakage between valve seat and valve face after regrinding or replacement.
- Helps ensure proper sealing before lapping, often reducing or eliminating the need for extensive lapping.
Fuel Injector Seat Leakage (Cylinder Head)
- Verifies the sealing of injector bores and seats in the cylinder head—critical in modern GDI and diesel engines.
- Prevents combustion gas or fuel vapor leaks into the cooling or oil systems.
Water Jacket Cap & Core Plug Testing
- Confirms sealing of water jacket closing caps (freeze plugs) in the cylinder head or block.
- Detects minute leaks that could cause coolant pressure drops or overheating.
Oil Gallery Core Plug Inspection
- Checks for leaks around oil gallery closing plugs, often located in the head or block ends.
- Ensures oil pressure integrity and prevents internal leakage.
Ideal For:
- Engine rebuilders and machinists
- Assembly Line in OEM Auto Industry
- Automotive service centers
- Cylinder head reconditioners
- Quality control departments
