Bobcat 751 SN:###-##-####with Kubota V1903...
Bobcat 751 SN:###-##-####with Kubota V1903 2EB
Has dense white smoke. I purchased this machine from an action this way.
It starts right up and smokes the higher the rpms the more it smoke. It smokes up the entire neighborhood with dense white smoke. Smells like diesel fuel.
I do not have any water in oil, or oil in coolant from what I can tell so far. I do not see anything leaking.
I have not used it enough to know if it suffers any power issues, but I don't think so. It revs and idles as needed just dense white smoke everywhere.What should I diagnose first to find out why and how to fix the problem ?

Hi, I'm Wayne.

I'll be assisting you with this issue today.

Thank you for coming to Just Answer

Your Question is as important to us as it is to you.

I am sorry to hear you are having this issue.

What you are describing can be from 3 things.

1st low compression in the cylinders

2nd is worn/burned valves.

3rd is worn out injectors.

I suggest doing a compression test.

Or start with installing rebuilt injectors.

I hope this helps you.

Ok, thanks. I should also mention that the auctioneer had this machine running and there was no smoke etc. They usually sandblast and paint when they have good running machines so they can get more money at auction. So they did blast and paint this machine then the day of the auction they said it would not start and was smoking like this so they sold as is not running instead. When I got it home it started right up but with white smoke as described.
Can I test compression with worn out injectors ? I assume I take out the injector and test during the injector replacement etc. ? thanks

Hi,

Thank you for the response.

I go offline between 2-3 pm CST, but do check in.

Judging what you mentioned, I would start with injectors.

Wayne
