The Aluminum Weld-In Bung is a specialized oil cap replacement designed for use with General Motors engine blocks from model years 1987 to 2015. This product is ideal for marine mechanics, boaters, and engine builders who require a reliable solution in high-vibration and saltwater environments.
Constructed from aluminum alloy, this weld-on cap is engineered for direct TIG or MIG welding into threaded or smooth boss holes on GM engine blocks. Its design eliminates the need for fasteners or threaded fittings, which can fail due to thermal cycling and vibration, ensuring a permanent and secure seal.
This aluminum bung is particularly beneficial for serious boaters restoring or upgrading GM engines in various configurations, including inboard, outboard, or jet-drive setups. Its compact profile ensures compatibility with standard GM oil passage locations without interference from adjacent components.
