Kubota b2620 leaking Head Gasket

mike paulson · Nov 10, 2020

Only 370 hrs on a five yr old B2620 that has been maintained and babied and absolutely never overheated. I open the oil drain plug and get about a shot glass worth of coolant after a good sit. Must be really slight because I haven't had to add coolant to radiator or overflow. Called Kubota and asked them if this is something common for this little 3 banger and was told it's unheard-of. Also asked for an estimate and was quoted 1500 hundred bucks which pretty much says I'll be doing this myself.
So anyone out there experience this or heard of this? Just wanna check all bases before I pull this apart. Any info on needing the head milled or spots to check in the block. Thanks in advance..

Post again in the Kubota Owning/Operating Forum for better results.
Good Luck!

A new head gasket may fix the problem, or it may not. Further investigation into possible sources of the problem are warranted. Is there any other path for coolant to enter the lubrication system?
