Unhappy Tear down 1st rebuild and rebuild again help....

Hey All.
Whats been going on with everyone? Ok, here's my perdicament. My Hemi was rebuilt once about 5 years or so ago and supposably new pistons, rings, bearings, gaskets, cam N lifters were all put in. The rebuilder was a first timer(virgin) builder and messed up somewhere along the line and the motor wont turn by hand.
Ive been told to check the rods, bearings, crank, ect...
If I tear it completely down, will I be able to use all the bearings, rings again, or will it screw em up?
I have a Mopar guy coming over to look it over, but if he cant see it by eye, its gotta come apart. HG

Cool

if you really are in doubt about the inside just tear it down, the last thing you want is a suprise when its in and you crank it up, better safe than sorry.

Tear it down. Whenever a virgin busts his cherry it's usually a mess. <img src="graemlins/mwink.gif" border="0" alt="[mwink]" />

Geez, I hope this isn't indicative of a similar problem with my ride!

My recently rebuilt Chevy 350 is tough as nails to turn. I couldn't turn it using the center bolt on the damper, so I had to use the three minor bolts in the thing.

It finally did turn, but not before I nearly stripped the bolts!

By three "minor" bolts, I mean the three bolts that run the circumference at the periphery of the damper.

66; that's WAY too tight, something is definitely wrong inside. I suggest you plasti-gauge your mains and rod bearings. If clearances are ok there, you need to take it apart and get the main bores checked for trueness and the crank checked for straightness. Lots of hassle but less work than building a whole new engine when this one blows!

Hemi, I'd tear it down and check everything. Mic cyl walls, pistons, crank, bearings, etc. If you're lucky you will be able to use most parts, evcept gaskets. Had one simular that set for a couple years, found the guy used no assembly lube,he put it together dry. Since it had never been turned over was able to use all parts.

If its been sitting for five years I would spray some WD40 in the cylinders, let it sit awhile then try to turn it over.

i hope y'all took out the sparklers before you tried turning them over. i stipped my balancer bolt not doing it now i gotta tap it out. thanks again summit for that pile of crap balancer that was too long.

You can reuse anything you take out that aint screwed up. plasti-gage everything. if it every ran before be sure you put the bearings in some kind of organizer so they to back in the location they were in. esp:lifters in same holes, rocker balls in same rocker, pistons and rods all numbered (stamp them if they're not already stamped) main caps, all that happy #$%#. push rods don't matter.
