FAQ

Q1: How do I confirm this part will fit my specific Isuzu 6HK1 engine?
A1: The primary fitment is determined by the engine model. Please verify your engine’s model designation (4HK1, 6HK1, or 6UZ1) and cross-reference the part number stamped on your existing air breather assembly with our listed numbers (1-11740181-1 or 1117401811) for absolute certainty.

Q2: What is the function of the engine air breather?
A2: The air breather is a key component of the crankcase ventilation system. It separates oil from the blow-by gases that escape past the piston rings, allowing clean gases to be recirculated or vented while returning oil to the sump. This prevents oil loss, reduces emissions, and protects the engine from sludge buildup.

Q3: What is included in the delivery, and what is the typical lead time?
A3> The delivery includes a single, complete air breather assembly as pictured and described. Lead time begins upon receipt of payment and varies by destination. We prioritize processing and provide shipping estimates based on your location to ensure timely delivery to your project site or warehouse.
