Well, looks like the problem is definately mechanical. Got home, checked injection lines, cracked each one loose, no change in knock. Drove down the road and back. Knock is worse. Oil pressure still at the 1/2 way mark on the gauge. But you can feel it in the floor. And the steering wheel. And the shifter. And if you push in the clutch, and rev it up a little, you can feel it in the clutch pedal. Bad mistake letting family lend me the money to buy this thing. I still owe them $1400. I don't have the tools to fix this - just a cheezy hoist and engine stand that would barely hold an Oldsmobile V-6 diesel. I cannot afford to buy a hoist, new engine stand, and whatever else is necessary, not to mention a new crank and bearings.
I'm asking for your suggestions here - should I sell it as-is, put it up for auction, part it out? This is the worst. It took 12 years to finally get one of these, and now it has to end so soon. :{
. I'd drop the transmission at the very least, and check that out. It sounds like driveline/drivetrain to me, but you never can tell over the internet. If it is under 500K, has never been blown up due to overheating or high EGT, I wouldnt think it's rebuild time just yet. These engines are hard on drivetrain, though, esp the older ones.
