    2004 Tahoe Engine Surge and Stuck in 3rd Gear - 5.3 4L60E

    Went with my older brother to look at a 2004 Tahoe with a rebuilt 5.3 with only 5,000 miles on it. I took it for a test drive around the town we were in, doing about 40mph at most, floored it once or twice for a second, everything seemed fine. We bought it and I drove on the interstate to get...

    2000 Suburban 5.3 LM7 Engine Replacement

    Need to remove and replace the LM7 5.3 Vortec engine in my 2WD 2000 Suburban LT. It has a spun rod bearing that is not fixable without removing and rebuild. I need to remove it and swap it with a good used engine of the same type. I only want to direct swap this engine with the same model...

    2000 Suburban 5.3 Engine Knocking

    Update on the "knocking" motor... Got it bought and towed to where I can work on things. Because the tow truck driver didn't have a winch, it had to be started and driven on the trailer. Pulled itself nice. When I made it to my destination, I drained the oil and there was actually 5 about...

    2000 Suburban 5.3 Engine Knocking

    Isn't there an low oil light on the cluster with the needle oil pressure gauge or is it just the needle pressure gauge ? Sensor screen maybe clogged ? Sensor failed without a DTC ? Failed gauge needle ?

    2000 Suburban 5.3 Engine Knocking

    Yea I did to see if the engine was milky. As I was looking at that, is when he started telling me about 1 quart being in the motor, and that isn't definite. Motor fired right up and the knocking is external, no knocking from inside the motor. Only ran it 2 minutes, here's a video of the gauges...

    2000 Suburban 5.3 Engine Knocking

    Well I just diagnosed it...it's either a bad flexplate or TC bolts being loose. Scanner brought up no codes, and the check engine light wasn't on. Passenger side valve cover is oily and on the exhaust manifold to block on both sides has little soot or oil from the valve covers. Pulled on the...

    2000 Suburban 5.3 Engine Knocking

    Going to take a look at things this afternoon. Put my scanner on it, check oil pressure, use my stethoscope to listen internally, drain the oil to look for metal shavings About the same thing I said, sounds like something external loose and wobbly knocking around. Me and a few other guys are...

    2000 Suburban 5.3 Engine Knocking

    What's the deal with the wiring harness and computer ? Does replacement require replacement of the computer and wiring harness and reprogramming of the computer ?

    2000 Suburban 5.3 Engine Knocking

    Worst case scenario, I have to replace the motor... There's a local guy with this engine and wants $750 with the computer and wiring harness. I've swapped a gen 1 350 from my old '79 Impala once before, how much harder is it to replace a LS engine ?

    2000 Suburban 5.3 Engine Knocking

    I'm thinking and hoping this isn't an engine knock, but something else producing the sound of a knock. 1. Piston slap - GM says this is "normal" for these engines and there's nothing to do about it : 2. Stuck/collapsed lifter/pushrod : 3. Clogged Catalytic Converter : That's what I'm...

    2000 Suburban 5.3 Engine Knocking

    I'm not too confident he knows the water pump failed...said he didn't even think of checking the thermostat. He's letting me go check things out the coming up Sunday. I'm going to put it on my scanner for codes, start it and let it run for a couple of minutes and check the oil pressure and...

    2000 Suburban 5.3 Engine Knocking

    I'd hate to do that before buying, he realizes it ain't an engine knock, and he raises the price back up from our $1k deal. I'm thinking and hoping this isn't an engine knock, but something else producing the sound of a knock. 1. Piston slap - GM says this is "normal" for these engines and...
