Experiencing a fuel leak at the rail connecting to the injectors and a malfunctioning temperature gauge. Currently awaiting a new sensor as the gauge cycles when the key is turned. Additionally, there is noticeable blow by at 3100 hours of use. Difficulty finding information on normal operating temperatures, especially in high ambient temperatures exceeding 85 degrees. Temperature readings show 190-208 on the block, 170 on the pan, and some areas reaching 220-240 and occasionally exceeding 250. Photos are attached, with a video upload attempted. Refer to IMG-6717, IMG-6714, IMG-6712, and IMG-6713 hosted on ImgBB and ibb.co. Check out the video "unnamed" on Streamable.streamable.com.
The temperature readings seem within the standard range. "In the past," the recycling workers preferred the Duetz engine for its durability, often operating it at temperatures exceeding 220 degrees Fahrenheit. Regarding the fuel leaks, are you referring to the small hoses that connect to each injector and the return line? If so, you can find the correct hose in a bulk "kit" at Bobcat parts store.
In a nostalgic reference, crewchief888 mentioned that the temperatures seem normal for the Deutz engine, which used to run at over 220°F back in the day. As for the fuel leaks, if you are referring to the small hoses connecting to each injector, you can find the correct replacement hose in a bulk kit from Bobcat parts. I'm relieved to hear that. While waiting for the OEM sensor to arrive, I decided to install an aftermarket gauge and sensor for added safety measures. I managed to fix the leaks by replacing the dried-out 3.5mm hoses with ones I found on Amazon. I also added a heavy dose of injector cleaner to see if it improves the performance.
Answer: Answer: The fuel leak at the rail connecting to the injectors could be due to a faulty injector or a damaged fuel line. It is recommended to inspect the components for any signs of wear or damage.
Answer: Answer: To address the malfunctioning temperature gauge, it is advisable to replace the sensor that controls the gauge. If the gauge continues to cycle when the key is turned, the sensor replacement should resolve the issue.
Answer: Answer: Normal operating temperatures for a Bobcat 863 G typically range between 190-208 degrees on the block and 170 degrees on the pan. However, temperatures reaching 220-240 degrees and occasionally exceeding 250 degrees could indicate overheating issues that need to be addressed promptly.
Answer: Answer: To mitigate the blow-by issue at 3100 hours of use, it is recommended to perform a thorough inspection of the engine components, including the piston rings and valves. Addressing any wear or damage in these areas can help
