RTV 500 smoke

[Lucky Tig]

My Kubota RTV 500 (gas) started losing power, bogging down, and belching huge clouds of odorless white smoke. A local dealer said there was nothing wrong with it, just my imagination. Another area dealer solved the power problem but not the smoke. (Of course when he tested it, it didn't smoke.) Now it is doing it more and more frequently. Hope someone out there can solve this problem.

I second that, sounds like coolant...

I would pressure test the coolant system. Was the RTV ever overheated? It could be a bad head gasket, warped head or other issue allowing coolant to enter the combustion chamber.

Thanks.Your diagnosos makes sense. It's never overheated but I will pressure test the coolant system.
