Bx 2350 coolant and motor

[hondaracer304joey]

I have a Kabota BX 2350 with a D902 – E2 motor that has been on its side. all liquids and fluids have been dropped out of it and replaced ran fine for a year then lightly started to smoke. Replaced injectors still smoked tore down engine replaced head gasket put back together made it even worse. Then it really started smoking so upon teardown, I noticed that the intake manifold and the muffler were full of coolant, what direction should I go now? New head or new block ? New parts include new injectors, new injector pump, new head gasket, new fuel and oil filters new air filters, new belt, new manifold gasket new thermostat and new thermostat gasket.

It's very very, rarely a block issue, it's all most always the head or head gasket!

Thank you for your response.
I just tore it down again I noticed on the prank new gasket that the copper gasket sealer I used some very small ports may have been blocked also around the piston the gasket had damaged I will attach photos.

Did you use a genuine Kubotahead gasket?
If yes, DO NOT PUT any sealer or coating on it under any circumstances!!!! They are made to install dry only.

No that was not it that I used . I did just order another head gasket though. I inspected the head and see no cracks.

So by using that copper gasket sealer it may have caused this issue ?

The only way to know if the head has any cracks is to have it magnafluxed. The local machine shop will check a head for $25 and it takes less than 5 minutes. The sprinkle a magnetic powder onto the head and then apply an electrical current to the head and at the crack the powder will stand up. It has been a while since I had a head checked, but did have a few intake manifolds checked for cracks before I found a good one. Having it checked will give you peace of mind knowing that you will not have to do the job over again. When I install heads, I follow the torque bolt pattern and start off with low torque and work my way toward the final torque in 20# increments. Some people tend to do it too fast which sometimes can bite you in the rear.

Thank you very much I appreciate the advice.

You might want to replace the head bolts with new ones since you are having repeat issues.

They may have been stretched and are not really applying the proper force into the head.

So the head was good got a new gasket and wend to install with old head bolts torque down to 47-fp then to 50 then the head bolts started snapping got two deep decided to take all head bolts out and start new lesson learned. Might have been my problem this whole time.

There is no reason not to reuse the head bolts unless someone tries to overtorque them.
The WSM lists head bolt torque as 27.5 ft-lbs to 31.1 ft-lbs.

I ended up getting new head bolts triple layered steel head gasket got it all back together and it leaked way worse 3rd time so now I’m guessing cracked head ? Pictures attached
