Lets just say the weather around Southern Colorado's been nice. Rain and snow thursday, more snow friday back to rain. I had an hour to kill on friday, picked up my son at the bus stop and made a b-line for Hills near PMI. When its dry the hills aren't much, but the motocrosser's love it. When you have as much rain and snow that we got its a downright sloppy muddy mess. So here we go alone (first major mistake!) trompsing though the mud laughing like little boy's. All is good. I proceed to climb right up a little slope, turn to the left and the truck starts sliding off camber to my left into a small gulley. I can feel the right rear get really light. I Yell to my boy sit back and hold on! I turned into the slide gunned it and got the truck to straigten up and drive into the gulley instead of flopping into it on my side. Pucker factor was way up there. So now I'm in a gulley full of mud with the sides at least 5 foot tall. I see a spot I might be able to pull out of if I can steer into it. Needless to say I can't and get hoplessly stuck with might right side in a bigger hole than the left. My crappy 33's would not clear out the clay like mud I was in. So A quick cell call out to my buddy Bill with his 83 3/4 Suburban to the rescue. He was itching to get dirty anyway so I did not need to plead for help. His sub is a beast compared to my K5. 35's 6" lift and a banks turbo'd 6.2 with a 12k winch. He yanked me out with no problem right into field of goo that my crappy tires still would not get me out of. Another yank and I'm free. We both figured we better head out before my luck runs out and I really do something stupid. Nope, can't call it a day with out causing some damage. As I'm following Bill out, he runs down a hill though a giant puddle maybe 1 to 1 1/2 feet deep. I'm sitting on top of the hill saying to myself "hmm, Bill did it, I should be able to too." So I haul it down the hill for some momentum hit the puddle and sikp accross it. I made it but the engine stalled as soon as I hit the other side(major error #2). Uh oh....Cranks but no start...Crawl out and take one look at the air filter and it's soaked. So I pull the air cleaner and the inside's dry, no major water got past the filter. The distribitator cap was soaked, so I pull it, spray it with WD-40 and wipe it out. I got spark now, takes a looong time of craning to fire up. (realized later I bumped the timing slighlty taking the cap off and on again). Now it runs, but it makes a pretty nasty sounding noise. Its rises with rpm but sounds like I put a big hole in the exaust. Too wet and muddy to check at the time. Oil pressure is rock solid at 40-60 driving. Engine really has no noticable loss of power. Yesterday was dry, so I fire it up and crawl underneath to investigate. I did find a crack in one of the header tubes to the collector, but its not that big. I can hear the noise better down here. Not feeling it in the oil pan, but I do notice the dust cover to the front of the bell housing rattling in time with the noise. I put my hand on it and it didn't quiet up. It feels like the noise is coming from the flywheel/clutch area. I'm wondering what the hell I could have done. It ran fine until I dunked it. I don't think I hydrualic'd it, it turned over just as normal immediatly after the dunk. The starter did start to sound funny since it took so long to crank back up again. But it still cranks right over and fires up. Could the starter drive be hung up and touching the ring gear? Or did I crack the starter nose cone and thats causing the drive to hang up? This is so wierd, the engine runs fine, I know I got a wicked exhaust leak but this other noise bugs me. Its raining again today and really can't crawl under it. Plus I got to head out of town tomorrow and really wont be able to mess with it unitl next weekend. Anybody got a guess as to what carnage might be the source of the noise????
