      That's very kind of you, That motor had a lot of miles on it when I did this but it ran fine, I pulled the head off and took it to a shop and for a $190. They redid all the valves and guides. And while the top and bottom were off.I pulled the pistons and put new rings on each and honed the cylinders. I think I put another 70,000 miles on it since that.

    I did this in my civic, needed to change piston rings,(stock engine). I cleaned oil off the bolts , mark bolts with paint, honed cylinders and replaced rings. Bearings were put back in original position, bolts in hole it came out, and torque back to paint line. 10k miles and no problems( stock engine).

    Thank you for you advice, this was done years ago and I've put 67k miles on it since that rebuild. I guess I'm just lucky. Not sure where you got the impression that I didn't remove the head, had it rebuild in a machine shop for $190. new valve guides, valves and seats ground, my grandfather did this process on his tractors often and kept them going forever. This is a jeep, much like a tractor. Now, in my race car, I paid Art Crisman 50k to build my big block. Thats a different story. Also in my TH-cam. Thanks again.

    It also helps to clean the crankshaft first, just to be sure no metal shavings, dirt, or debris of any sort is in between the bearings and crankshaft. It’ll sucking doing it all over again in 10,000 mile or less, except the second time you’ll be getting the engine re-honed, new crankshaft, and possibly pistons more than likely. Awesome video though, especially with this particular vehicle.

    I have a 2001 Ford Taurus with 3.0 ohv.
    I found it easier to take a thin long flat head screwdriver (3mm wide) and lightly tap the old bearing until enough of the other side of the bearing was showing. Some people use a wooden popsicle stick to push out the old bearings, basically any thin piece of material softer than the crankshaft metal could be used, though stiff enough to hold it's shape while hammered lightly.
    After that I was able to get some of the old bearings out just by rubbing it with my thumb, sometimes turning the crankshaft would turn the bearing and that helped getting it out. Some people use a pair of needle nose pliers to pull on the part of the bearing left showing after tapping them with the screwdriver.
    Putting in the new bearings was easier, for almost all the bearings I was able to push them in nearly halfway with my thumb then I used the wooden end of a rubber mallet to tap them in all the way.

      There may be issues regarding the clearance between the crankshaft and the bearings.
      The standard approach when it comes to replacing the crankshaft bearings is to remove the crankshaft and measure the mains, if the mains are within spec then use standard thickness bearings.
      IF the crankshaft mains are worn down, then all the mains are ground down and thicker non standard bearings are used.
      By taking the shortcut in the video we may be installing standard thickness bearings on a crankshaft that may be worn down, so the problem may go away temporarily.

      That's a great question, there is a tolerance for some movement but you need to use something called a plastic gauge to squeeze in side Your Rod and the throw on the crank, and then you pull it back out and measure it with a micrometer and see if it's within the tolerance, if it's not within the tolerance then I would have the crank ground, and they do that in 10,000th increments (.010) and then you buy the bearing to make up for that difference.

If when you pull the bearings out you see lead and the color of copper you should be good just change them out throw it back together. I wish you the best of luck.

      I believe you would have to have your crank ground, and I believe they do that in 10,000th increments, (.010) I did not have my crank ground so I put stock bearings back in, I've probably put another 50,000 miles on it since, and it's running great has more power and doesn't stink. I also pulled the head off and had all the valves reground new valve guides and he flattened the head, that was only $190. Mine is a straight 6, and I pulled the Pistons out and put new rings on them.

      When I'm showing here is not the rod bearings, the bearings on changing here are the ones that the crankshaft spins on, you have to understand my motor was running fine it just had 250,000 miles on it and this was preventive maintenance.

    This works great, the mains came out and new ones back in easy. With the exception of the main thrust bearing (center most). I cannot get the upper half of main thrust bearing to go back in. I've checked clearances on the sides and they are ok. (looking for any points that might be causing an interference fit). I went so far as to cut a short piece out of the old main to insure alignment (I tapped this in with a brass punch), then placed the upper thrust bearing on the crank as described in the video. When I rotate the crank, the cotter pin tries to ride underneath the main thrust bearing upper half. Frustrating...
    Continuing to try this over and over is the defn of insanity. Has any one done this successfully? I realize this is a very tight fit. I tried loosening the other main caps to see if I could get more clearance.
    Worse case, can I remove the crank with the engine still the truck?

My family has a Mitsubishi 4G69 motor in a Gallant, I changed the oil and used that long life garbage and half of it leaked out the front main without tripping the low oil light. The engine now sounds like a diesel, Is that indicative of some wear on the main bearings?
    I'm thinking about pulling the motor and replacing them along with the piston rings, motor has a 181k miles on it.

If you can do the work yourself you will save a lot money.

This is a carpet cleaning van and runs off a pto. So it runs at a high idle for about an hour at a time equivalent to 50mph. The engine still has run smooth for the last 2 years. The the other day I noticed when I came out, the lifters were ticking. Went away as I got to my next job and the same tick after the next job. I put some Lucas in it and the pressure dropped to 0! So I removed the oil pan and found the pick up tube o ring was flattened and dry rotted. I thought that would solve my problem. I was wrong. So I installed a new oil pump. Pressure came back to the 25 psi but soon as it got to operating temp. It went back to 0 again. Due to covid I don’t have the funds for a new engine. I’m hoping changing the bearings will get the pressure back. But I find it strange the engine sounds smooth with no knock. When I removed the flash pan to where the bearings are, everything looked good. I wiggled them and one dose move side to side but not up and down. I also checked the sending sensor and it is good. This one also don’t have the screen. There’s only one pressure relief doing in this engine which is in the oil pump.

      As long as your motor is not making a knocking sound, and you're just doing this as preventative maintenance, I would just put the same size right back in, if the crank has already been ground before it'll probably say on the back of the bearing you pull out ".010 or .020" they usually grind the crank in 10,000 increments so you just go with the next size bearing. But same as what was in there if you're not grinding the crank. Wish you best of luck, it's a lot of work I know.
