Multiquip M1327200004 Blow-By Hose (JPN) - OEM Replacement Part for Super Silent Generators

The blow-by hose routes crankcase gases from the engine ventilation system on Multiquip Super Silent generator models equipped with Isuzu 4LE2T Tier 4 Final diesel engines. This critical emission control component ensures proper crankcase pressure management by venting combustion gases that escape past the piston rings during normal engine operation. In turbocharged applications like the 4LE2T engine (33.5 hp at 1,800 rpm, 133 cu. in. displacement), effective blow-by ventilation is essential for maintaining optimal engine performance and preventing oil seal damage or contamination.

Failed or deteriorated blow-by hoses can cause excessive crankcase pressure buildup, leading to oil leaks, reduced engine efficiency, and potential damage to gaskets and seals. Regular inspection of this hose during routine maintenance intervals is recommended, particularly when checking the 2.8-gallon lube oil system or performing the 10.5-liter oil service on these water-cooled, turbocharged engines with cooled EGR and DOC exhaust after-treatment systems.

This blow-by hose is compatible with the following Multiquip Super Silent generator models:

• DCA20SPXU4F (20 kW Prime / 22 kW Standby)
• DCA25SSIU4F
• DCA25SSIU4FC8
