Bobcat s130 Kubota v2203 MDi Diesel engine smoking issue
Hi guys. Recently purchased this bobcat with 3k hours on it. Compression is 450 across the board all 4 cylinders. Bought it with this smoking issue and figured I could figure it out. First thing I did when I bought it was drain and change with fresh fluids and filters all across the board everything. Next step in pop tested the factory injectors and they were popping early about 4-500psi early and also had leaking nozzles before pop. Figured at that point my smoking issue was due to the injectors. I bought 4 brand new aftermarket (I know) but figured it would be worth a shot since I have used aftermarket injectors before from this company in diesel equipment and never had any issues and they spec'd out to be just like factory. I bought the injectors and pop tested all 4 of them before installing and all passed the test with factory pop pressure, spray pattern and also no leakage at the nozzles. I installed them and still smokes. My next thing I did was check the valve clearances which were out of spec. Set all valves to factory spec and installed new gaskets along the way. Still smokes. My next idea is to do a spill test on the pump to check timing but I hear they don't ever or rarely ever need to be adjusted. Please chime in and give me some ideas or tips of things you have seen or fixed with similar issues. I want to fix this so I could use it. Another thing for you is when I stand near the machine when it's smoking, my eyes sting at some point and my throat gets irritated. I'm thinking 100% this is a unburned fuel issue or fuel issue in general. This is for all you diesel guys out there, please help me out and give me some tips. I will greatly appreciate it and love this forum. 🙏
