Plastic Film Bursts From Engine Cylinder Pressure 💥⚙️

This video shows a simple engine diagnostic method where thin plastic film is placed over the cylinder opening to visually test combustion pressure and sealing performance ⚙️
As the piston moves upward during the compression stroke air pressure rapidly increases inside the cylinder creating enough force to stretch and eventually burst the plastic film 💥
A strong and sudden rupture usually indicates that the cylinder is generating significant compression pressure which suggests the piston rings valves and cylinder walls are sealing relatively well 🔥
If the film only weakly inflates leaks slowly or fails to burst it may indicate worn piston rings leaking valves damaged head gasket surfaces or low compression problems ⚠️
This method is not a precise scientific compression measurement but it provides a fast visual indication of cylinder pressure behavior without specialized testing equipment 🔬
