I am between a 24K service (Throttle cable upgrades and a engine oil and oil filter change) on my 99 LT. I also did some other service (like bleeding the brakes, etc) that's not relevant to this topic. I had to remove the fuel rail for the throttle cable upgrade. I thought I had put her back into a working condition. I had drained the old engine oil and replaced the oil filter with a new one. I fired up the engine for a 15 to 20 seconds but quickly realized I forgot to add new engine oil. So I turned the engine off. After a few hours I added approx 3 quarts. The oil level in the window was a little over half way so I started the engine and it drank the oil. Oil level went below the minimum mark so I stopped it again and added more oil. Now the oil levels are fine.
Almost done with most of my service so I washed the bike and went for a test ride today morning. There is a rattling sound from the engine and after approx half a mile of ride the red oil light (I believe its low oil pressure light) came up. I continued cruising along at approx 25-30 mph and parked it. Most of the threads indicate that the oil filter might be lose or the old oil gasket is stuck inside. I plan on checking the filter tonight to ensure its tight and I am sure the old gasket (the black rubber ring) is on the old filter that I removed.
- Was I supposed to add oil to the new filter before mounting it into the engine?
- Have I damaged the engine already ?Can the rattling sound be due to damage to the engine? The sound reduces as the RPM increases. I allowed the engine to reach 4000 RPM once just to check the engine response.
- Can low oil pressure cause engine rattling noise?
- When I was changing the throttle cable I had to remove the fuel rail. While putting the fuel rail back into place I observed that the 4th cylinder fuel injector went in all the way and a slight locking action. But the first three did not have similar locking action. I still observe a small portion of the yellow fuel injector ring after the installation. However the injectors seemed to be fit snugly.
- Should I focus on fuel injector's or the oil filter as my problem for rattling noise?
