That would definitely explain your oil leak problem. Simple fix and probably didn't cause any harm but would still **** me off. They're listed in the main cap tq sequence. Granted they're the last step but someone who does this crap for a living should be on their game.
I see, but that is internal to the oil pan, why would it cause an external leak that appeared to be the oil pan gasket??

Ya know I got the same crap too about "we will put our best guy on it" and the kicker is when I called the service manager and tech out on the crushed parts they said they knew about it and didn't think it was a big deal! The tech actually got a attitude with me because I was pissed about it! If it wasn't for the fact that I have a LTC in the state of mass it would've got ugly quick but if you have any assualt and batteries against you with a LTC, kiss it goodbye forever. Guess who paid for the headers in my sig?LOL!

No it's not. Look up under your truck and you can see the crossbolts on the main caps not too far above the pan rail. The oilpan on an LS is below anything crankshaft related as it's a bulkhead design. I remember laughing to myself when you said you would let them rebuild it...... and I see they didn't disappoint by doing an excellent job of it.

So just ask yourself.......... what else did the master parts swapper/lube bay technician that rebuilt it forget to install and or torque to spec? How about clearances........ slap it together and hope for the best?

Please, really, just sell it.

thanx for the explaination on the crank bolts.

I see your point, and as I mentioned earlier, who knows what else they may have done incorrectly.
One other thing I told them fix last time it went back, the top bolt for the bell housing to the block was falling out, beyond that, the bolts and nuts were not oe, just black steel crap with no flanged nut and not anodised like oe. Where did my oe bolts go?

I think I will find a new truck, same as mine and swap my mods over, no biggie,

Beats me Gonzo, the block went to a machine shop, I don't know where it was re-assemlbed,
there or the dealership, either way, poor workmanship and qc.

Wow. Just wow. I don't even know what to say; did they include any sort of engine warranty in addition to your factory warranty to guarantee workmanship on the rebuild?

Also, I would contact GM directly regarding that experience and tell them, in no uncertain terms, that you are in no way comfortable relying on the quality of the rebuild on your engine due to the massive oversight in proper reassembly that has already been documented with said engine rebuild. Maybe they can do something for you; I would seriously want a new shortblock installed at a reputable dealer.

Yes, actually this is a very valid point. You have been more than willing as a customer to let this dealership get things right with an exceptional level of patience....... and in return you are getting third rate quality and workmanship. Now whether the engine shop screwed this up or not the onus falls on the dealer as they farmed the work out in the first place.

I would put all your papers together and contact GM. I mean the work orders alone for the oil pan showing it took them three times to figure out you had cross bolts in the main caps missing should raise some eyebrows........

I mean if that kind of thing fell on my desk ( being a regional rep) that dealer would have hell to pay. It's that sort of garbage workmanship that drives customers to buy something else altogether. Customer satisfaction is key in their business and they should approach you and ask what would make you satisfied. My response at this point is I would want one hell of a deal ( ie straight across trade) on a replacement equivalent truck and that dealer can eat the loss and send yours to auction. It's actually not unreasonable........ There are companies out there that would do what I just said to keep you satisfied. Unfortunately I do not believe General Motors is one of those companies.

It is still worth pusuing........ but another replacement engine or whatever would not be "satisfaction" at this point. You have put up with enough poor workmanship with this truck for an entire lifetime.
