Overview
A first-person owner walkthrough of a full head gasket R&R on a Yanmar SA424 (3TNV80F engine), roughly 30 minutes long. It covers disassembly sequence, radiator and water pump removal, parts sourcing pitfalls (TNV76 vs. TNV80F gasket differences), reassembly, valve lash, and an honest ending: the repair didn't fully solve the exhaust-into-coolant problem. Best for owners tackling the same job who want a realistic, unfiltered account rather than a clean how-to.
Posted by the cvsahara channel, which appears to be an individual owner working through this repair on their own tractor with no professional shop background evident.
