Brutis
Work in Progress
O.K. I've been bouncing all kinds of ideas around in my head (and others too - especially my dad), but tonight I may have finally figured out the real issue with my truck.
I've posted a couple of previous threads relating to what initially seemed like a major engine problem. Truck would bog down and grind to a halt when starting. Eventually would start and make a horrible rapping sound. I found oil leaking out the drivers side valve cover as well. So my truck sat for about a month b/c I had no time to mess with it. This weekend I swapped out injectors with some that I knew were good (tested BBs) and changed the oil (Oil pan was flooded with fuel - I completely overflowed my 12 quart drain pan). The truck started fine and actually sounded fairly good too. It did shudder and vibrate alot and there was still an intermittent clatter. Idle speeds seemed close to normal.
I pulled out my stethoscope and listened to every cylinder everything sounded fine. But still the rapping sound. So I called my wife out and asked her to point to were the sound was coming from. She pointed at the radiator.
I had kind of been leaning towards the front of the motor for a unusual sound as well - earlier thought maybe a fan clutch problem. I crawled under the truck and noticed that one of the corners where the radiator mounts was broken and causing the rapping sound as the motor shook. Great! I found the noise But what caused the problem in the first place?
Would I be way off base to think that the problem all along was a bad injection pump that caused the cylinders to flood, mess up my timing (causing the shake), and hence breaking the radiator mount? That's where I'm leaning right now, so I may be a pump swap (I have one) and dynamic timing away from running properly?
Sorry for the super-long post, but I wanted to get the background in to make things clear. I'm so excited to think that my truck may be running again soon!
I figure if OB can't figure it out no one can. Any thoughts?
Thanks a ton!
