My car has lost power, the crackling noise has become muffled, and the engine oil is turning black quickly, and now it is starting to misfire Diesel drips through one of the four pipes, and when I change gear and downshift it smokes.

Hi,

This vehicle isn't offered in the US. We do have the Toyota Sienna, but none of them came here with a diesel engine. However, I will try my best to help.

You indicated the oil getting dirty faster and a crackling noise. How fast does the oil get dirty and I'm not sure what you mean by a crackling noise. Additionally, one of the 4 pipes leaks diesel. Which pipe are you referring to?

Let me know that. Also, if you have a power loss and are seeing diesel fuel coming from the exhaust, the first thing I'm going to suggest is a compression test to see if we lost compression in one or more of the cylinders.

Next, let me know the van's model. Is it a Sienna?

Let me know.

Hi,

I'm sorry, but I don't recognize the word Candetta. I tried to search for it on Google and got nothing other than the surname for families. Can you take a pic of the component and upload it for me to see?

Thanks,

Joe
