I’d say @ $700-$1200 depending on where you go for the rebuild. VT247

How much does a good re- manufactured 3.4 engine cost, including labor.

Xavier Holland says:

Lol random duck sexy stare. 😛 Dude, nice swap. I too have the v6. Plan to
keep it for as long as it will move, then pull a block, and move it some
more.

Vacationtime247 says:

If it’s coming out the top, then all those things you mentioned earlier
don’t need removed. Be careful of the radiator not to knock a hole in it by
accident. From what you’re saying, it should be ready to pull by hooking up
the chains and lift. You going to put the heads on after dropping the block
back in? VT247

Mike Thexton says:

Hey, chiltons says to remove these before removing the engine Stabilizer
shaft links from the lower control arms Tie rod ends from the steering
knuckles Lower ball joints from the steering knuckles Cooler lines and
bracket from the transaxle Is that necessary, or can I skip these steps?

Vacationtime247 says:

I’ll bet the whole front subframe comes out in their instructions. In some
applications this is the best way to do it. Drop the subframe, lift the
body and you’re at the motor. From there it’s just removing the engine /
trans bolts, motor mounts, & torque converter bolts. But yes, all those
things mentioned need removed before dropping the cradle. VT247

Mike Thexton says:

Yea, I think It would be easiest to assemble the new engine while the
blocks in the car already. I don’t exactly have a scissor lift or anything
just a jack, so I’m not sure If I could get the frame high enough to put
the engine in from the bottom. I would love to invest in a scissor lift one
day though!

Mike Thexton says:

Well, I have everything removed from the top, the entire engine bay is
empty minus the block, it is sitting on the frame of the car and is only
bolted to the tranny still, It looks like I can throw the chains on it and
unbolt it from the tranny and lift it out? It’s as disassembles as if I
were doing the head gaskets again.

bra’s cause rust and paint fading

@curley920 Lawn will get mowed, eventually. VT247

I have a 00 grand am gt and it blew the lower intake manifold gasket at
149k miles. It was pretty easy to do. Put a fle-pro gasket on it and some
silicone on it. Im at 159k and no problems. My question is how long did it
take you to swap motors? And would you know how long it would take to do a
tranny swap? Starting to slip under hard acceleration only. Nice video btw
thanks

Joey Nash says:

how did u do ur cold air intake???

bteeuwen says:

this is the 24v 3.4L right? haven’t heard the greatest thing about them but
there is a lot on the road though.

Vacationtime247 says:

@forestcamper Guess that all depends on where you get the new engine from.
You might get everything if you get it from a salvage yard. If you get a
new engine from Autozone or otherwise you might just get the block and
heads. VT247

Vacationtime247 says:

@MrRichierich1990 If your car is bubbling out violently, like you hear a
pshhh with steam coming out or the overflow tank is bouncing and gurgling
there is a problem. Two main culprits would be the thermostat stuck closed
or the water pump isn’t pumping water through the sytem. What does the temp
gauge read? If it’s reading high, check the pump or thermostat. VT247

Vacationtime247 says:

I only unhooked what was necessary to get the engine out. The old engine
that was in there had a knock. Got another engine but things had been taken
off or were no good. So I combined what I could to make one good engine.
When I say I had to ‘get’ something it usually meant it was swapped from
the old engine. Gaskets and a few parts were however bought new. True,
there is a bolt that goes the other way holding on the transmission. This
method works for me. VT247

Forest Camper says:

@Vacationtime247 Thanks for responding, I recently bought a lemon and the
previous owner is being extremely uncooperative. I’m evaluating my options
for damage control.

Vacationtime247 says:

@jfletcherwilliams If it’s not 12 volts at the brake light switch, follow
the wiring diagram back. Or, just wire in a 12 volt power source. Make sure
too that you have ground! VT247

Mike Allmon says:

how would that be considered a cold air intake when you are making it
breathe hot under hood air like that?

Vacationtime247 says:

@shawnwhite00 I cut the rubber line for the fuel. Put in a short piece of
steel line that was flared out on both ends. Double clamped it at both
sides for both the in line and the return line for the fuel. Those quick
disconnects suck! There was no way mine was coming loose. VT247

Vacationtime247 says:

Not exactly. All that work to make some $. Just so happens that it was an
Alero. I’ll buy any car if it’s cheap and can make some money on. Today’s
project, breath new life into a ’99 Durango I got for $500. VT247

Vacationtime247 says:

There are bolts holding on the transmission that you can easily see from
the front of the car. There are one or two (can’t remember exactly now)
that go the opposite direction in the back. You’ll need a long extension to
take ’em out. Also, don’t forget the torque converter bolts as well. The
rest is pretty straight forward. VT247

Casey Rodriguez says:

After market intakes lose power. They sound good, but lose power. It took a
cold air intake extended 2 ft in front of the car with 70mph winds to see
gains otherwise it’s just a loss of power.

Vacationtime247 says:

Way to much work. It can be done, but you’re going to have an enormous
amount of time and money into a project like that. Much simpler to just get
a Pontiac GTP or Buick Regal GS. VT247
