Dissasembleing The 5.9
OK I have an engine that looks to be in very good shape, It is showing some wear on the bearings so I am going to do that for sure. Now what I was thinking is this. I want to pull the pistons out and examine them and the rings and just make sure everything is ok and also to Blast the block with the pressure washer. If everything looks good I want to put the pistons back in with new rod and main bearings. Has anyone done this? Is there any reason It wont be ok to do this? As long as the Pistons go right back into the same holes they came out of I cant see any harm. There is Not even a touch of a ridge so the pistons will slide right out.

You're going to check out of round and taper of the cyl. walls right. You should be alright if everything checks out good. When I do inframes I'll put in new. main bearing, rod bearing, and rings. Just dont nic the crank when going back with the pistons.

check the cyl wall for taper and measure the pistons, check the wrist pins, check the piston cooler nozzles for debris, make sure they are clean, remove any carbon from the ring lands (grooves) lube them up good with clean eng oil and you should be good to go.
Look at the rod bolts and replace ant that show ant stretch, same with head and mains.
If you have the front cover off, take care of the dowel pin, loctite the oil pump mounting bolts, as well as all the timing gear case bolts.

con rods- 1st step to 22 ft/lbs
2nd step to 44 ft/lbs
3rd step turn additional 60 degrees
main bearings- 1st step 44 ft/lbs
2nd step 66 ft/lbs
3rd step additional 90 degrees
oil pan bolts- 18 ft/lbs
front gear housing- 18 ft/lbs
oil pump mounting bolts- 18 ft/lbs
flywheel mounting bolts- 101 ft/lbs
front pulley mount bolts- 92 ft/lbs
cylinder head- 1st step-66 ft/lbs
2nd step- LONG CAP SCREWS ONLY to 89 ft/lbs
3rd step- check short ones are at 66 ft/lbs
4th step- check that long ones are at 89 ft/lbs
5th step- turn additional 90 degrees
torque pattern is to start in the center and work towards the outside in a circular pattern.
small bolts in the rocker arm pedastal- 18 ft/lbs
valve clearance= intake .010, exhaust .020.
