WOW BeemerNut, thanks for the information. I will be dropping the crank off at the machine shop next week and will see what they say as far as rescuing this crank. Then I will have to weigh options: new/refurb crank or short block depending on their analysis. There is definite contamination...
Here are pictures of the Crank removed. You can see where the journal is white in color. I believe this is part of the bearing that is still attached to the journal, as you cannot see the oil holes. I have contacted a machine shop that is going to re-condition the crank for me. I did not...
At this point this is now becoming an engine rebuild project. I am in the process of removing the crank and will be taking it to a shop to assess and polish the journal.
Crank position 5/6 looks dry. No oil compared to the others. Any thoughts? My guess is oil starvation, possibly do to a slipped bearing, or clogged oil passage on the crank. Let me know if you have any other ideas. At this point I need to remove the rod cap bolts and see if I can move the...
Sorry for not replying. Life got in the way. Finally got the torque converter off. Ended up just drilling the bolts out. Will run a tap though the nuts on the torque convert to clean them up, but they look in good shape. With the torque converter now off, I was able to unbolt the Flex Plate...
I went ahead and removed the engine with the torque converter attached. Now I still have the issue of removing the converter from the flex plate. My idea is to cut a slot on the back side of the bolt with a Dremel and use a screwdriver (or impact drill or impact driver) to turn it. Once that...
I believe the cause of the seizure was oil starvation, but I do not know that for a fact. I was able to move the truck by putting the trans in neutral (had to push it up the driveway). I suppose it could be that the torque converter froze up, but short of that, I would think you should be able...
My LR4 has a seized engine that I am attempting to repair. I am preparing to remove the motor, but I have a dilemma. I need to be able to turn the crank to get to the flex plate bolts to disconnect the torque converter, but with the engine seized, I cannot turn the crank. I have removed most of...
