It looked like the tip was cracked, o-rings looked good, #5 same one I replaced about 7 years ago, came from BRD, the other 7 came in truck when new, the ICP looked kind of melted, I put glow plugs and new wire harness on to, I been running shell 15-40 oil since I had the truck, change it every spring weather it 500 miles or 3000 miles, don’t drive it all time, some say to run mobile 5-40 better oil, I just changed it Sept. when this happened, but due to all this going to change it now, along with antifreeze, it shore does start easer turns over one time and starts, use to be 8-10 times. Ok man thanks
