I recently purchased a 1997 GMC Sierra XC w/5.0l that wasn't running. After tinkering with it for a month I got it to run and drove it for about two weeks. I managed to replace the radiator, updated the spider fuel injectors, changed all of the fluids and filters. After that second week I was going down the interstate and noticed my oil pressure dropped to 20psi and the engine was knocking hard.

Donor vehicle, was sold out from under me......
Well, the guy I was supposed to buy the donor vehicle from, backed out and sold the rear end and other parts out from under me.
Don't know what to do, I am back looking for another donor.
Look here,

or here.

Plus there are lots more out there.
Chevy-Art, thanks for the links. I'll be removing my OEM 5.0l on Tuesday. I'm really just thinking about installing a 5.7l instead. I think it will be cheaper and get me back on the road. Although, if I manage to find a complete wrecked truck with a 5.3l that would be GREAT.

I found this on ebay......http://cgi.ebay.com/ebaymotors/01-04...item35b03805f6
and this

Is it a good deal?
if you have time to wait you can find a ls1 with lower miles on it for about the same price, i found a complete lift out that has 135k on it for 400...includes pcm and harness...i'm just afraid of the mileage.
but the 4.8 you listed is not all that bad of offer. just have to figure out shipping, etc.
I contacted seller, I was quoted $180 to ship to my work. $400 that's cheap!!!! Any leads?
Jose
I'm not afraid of miles....if it has to get rebuilt(re-ring) I can do it. No biggy. More than anything, I just want my truck back on the road.
i'd go for it then. i know for one thing, your fuel economy should more than likely be better. I was just talking to a buddy who has an 03 silverado and he is about roll 300k on his 5.3 ( no rebuild yet). i have heard alot of other people who have ran those motors 250k+.
Had the day off today and so I decided to tackle the engine removal. This is my first GM truck engine removal, I got it done in one day and with hand tools. I wasn't happy that I didn't bring home my air tools from work, it would have been a lot easier. Needless to say, I've also removed the oil pan..........Pics to come tomorrow.
Small update, haven't had time to take pics. I've sourced an engine. Picked up a 4.8l with accesories brackets, harness and ecu for $125!!!!!!! I've got to order the motor plate adapters and whatever else I need to mate the engine to my original tranny. I'm considering any performance add-ons while the engine is out. Obviously, a new set of plugs, oil and filter. Still thinking as to what intake I should run. Lastly, headers.......still undecided.
Sub'd and good luck. I want to do a 5.3L swap on my '96 GMC, cluster and all, as well.
Motor to go in today. Ordered the motor mount adapters, flexplate and spacer from Street and Performance. I've still got a lot to do. Here's a small list of items:
Items that I need
-4.8l or 5.3l starter
-MAF
-Coolant temp switch
-Several intake manifold bolts(missing when I got motor)
-fuel pressure regulator
-fuel rail cross-over pipe
-stock intake box and tubing
Items I need to make or modify:
-relocate battery to driver side
-custom make the new harness
-more of a wishlist item but electric fan setup
-lastly clean and degrease engine bay area
Forgot to add spark plug wireset and the metal heat protection tubes for the wires. Anyone know where I can source any of this stuff?
Well, I've managed to set the engine in the frame. I'm having an issue with lining up the clamshells with the motor mounts. I've got the pass. side in but the driver side is way off. Not too pleased with these Street and Performance motor plates. Or there is something I missed in the instructions.
I should be setting the engine in permanetly today. Ordered my fuel line setup for less than $50! Still have my intake setup to do, relocate battery, make the wire harness, secure new ecu. Still a lot of work to do.
Update: To my despair, I was sent the incorrect motor adapter plates from Street & Performance. I set the engine in and found out very quickly that the engine was sitting abour 1.5 inches to far forward. A quick call to S&P and I found out that I got sent the wrong adapters. Monday I'm getting the correct ones shipped out and a return slip for the others. Thanks S&P.

Well, I'm in the process of looking for a 5pin MAF, OEM intake setup, O2 sensors and finally one(yup only one) spark plug wire and metal protector. I'm hopefull that I've found an intake setup from a forum member. I'm still concerned as to how the 4.8l manifolds are to mate with my OEM exhaust Y-pipe. Lastly, will be my A/C setup as I'm concerned with running the engine first.
OH, most importantly, I'm in need of the driver's side fuel rail retaining clip for dual line setup. I'm trying to find a decent picture in order to show you what I'm looking for.
Borrowed picture to show the retainer I'm looking for desperately:

Reveived my starter yesterday and also my S&P adapters for the original coolant sensor and the original oil pressure switch. I really need that retaining clip for the driver side fuel rail. Anyone know the part number?
Today I got my S&P adapters today that move the engine back an inch. WOW, what a difference. I'm back to where I should be. Can't wait untill Sunday to be able to work on it again.
Also, my fuel setup was delivered last night. Dorman products supplied all the parts. Should be pretty straight forward.
Finally, sourced my intake setup. NICE.
Send me a PM with your address and i will mail you that fuel line retaining clip. I have a couple salvage yard 5.3l's and one had a burnt intake. You are welcome to the clip. Its one of the only things not melted on that intake! :)

Mr. Mike, sir you have a PM. I want to thank you, you are a life saver!!!
I can't wait till this weekend. I hope to at least get a full days work in. With all of these classes and midterms...I think my brain is fry'd!
Totally need the day just to relax..I plan on spending some time this week on finally bolting up the engine to the trans.
Keep the updates coming! I'm following this thread with anticipation!
I appreciate the boost of confidence. By the way, intake tube and air filter box arrived. Still need a MAF and the rubber pieces with the hose clamps in order to secure them to the intake and air filter housing. Not sure if I mentioned it before but I swapped the pass. side exhaust manifold for a non-egr unit. I want to make sure that I have the room for the a/c relocation kit.
OEM harness has been removed completely in order to thin out the wires that I will no longer need. The new harness is in and plugged in for the most part. My harness was cut so I'll have to patch up some of the wires.
I'll post pics soon.
Hows is this Coming,
My apologies for the lack of updates. As of right now it sits as it did on my last update. My friend and I had to come back to the truck and double-check the wires before they were to be removed completely from the harness. The new 4.8l ecu is going to be controlling the shifting duties so the trans. plug needs to be wired in. Quick reminder, I have an '01 4.8l with an incomplete harness so I'm having to patch a lot of wires.
Things still to do:
-locate a stock 4.8 or 5.3 Y-pipe from the manifolds
-upper and lower coolant hoses
-drill and tap water pump for the Throttle body coolant line
-tighten the motor mount bolts
-send S&P my OEM oil pressure switch in order to get the correct adapter
-still looking for the rubber O-ring with screw clamps at both ends of intake, one at the throttle body and the other at the upper portion of the airbox
Pics as promised, though somewhat late:
Before battery relocate and intake manifold install

pic of fuel line setup, these are Dorman products. Used the OEM fuel supply and return line all the way up to the bell housing!!!! NICE. Oh, quick tip, if you are going to do the hard plastic lines as I did.....get a cup of hot water to make the line soft enough to slide over the fittings. Be careful and go slow otherwise you can bend the line and it's useless then.

Mock up of the intake(note the missing rubber clamps I mentioned before) and the OEM harness is still in the engine bay. Currently, it's out getting "thinned" out.
http://i9.photobucket.com/albums/a82...1/IMAG0239.jpg
The OEM harness is complete. Now, we are working on the new harness and grafting in a few items from the old harness that were missing. My new harness was cut so I have to add in the A/c, tranny plug and MAF plug among other things.
I'm still searching for a y-pipe and the intake pieces to complete the install. Upper and lower radiator hoses have been installed and the oil has been changed. Oh, looking for one spark plug wire if anyone has a spare.
Hope to get this running within the next two months.
Small update, after seeing others on the forum with their intake and A/C setups, I'm really liking the idea of of the H2 intake. I may have found the y-pipe needed although I'll have to modify it to fit my setup. I hope to use the oem y-pipe off a Pontiac GTO. We'll see.
