Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.

Dear customer, due to the symptoms, you may be having problems at the level of the PCV valve or engine gas recirculation valve, this valve is the one that makes the gases or vapors produced by the oil inside the engine recirculated, thus the oil does not escape from the engine in form of vapor and also does not pollute the environment, but the oil always remains in vapor and the liquid remains inside the engine, when this valves begin to produce certain smoke leaks it is because this vapor is escaping somewhere. In addition, as the oil evaporation process is very slow, the loss of fluid is not noticeable, that is why i the symptoms points to problems in this valve.

My goal is to give you the best advice i can, I hope to be helpful, if you have any doubt or want to know anything else please do not hesitate to reply back.
Kind regards, Sebastian.

There is no PCV valve fitted to my Aixam crossline 600cc Kubota engine. So the problem is still here. Please advise

Hello,
It seems the professional has left this conversation. This happens occasionally, and it's usually because the professional thinks that someone else might be a better match for your question. I've been working hard to find a new professional to assist you with your question, but sometimes finding the right professional can take a little longer than expected.

Hi my name is ***** ***** does it start from cold.

Expert:  Gavin Perry replied 14 days ago.

I would get a compression test done on the engine but to be honest i would expect a cracked piston ring with how you describe the issue.
