Rodney Turner: Pontaic 2001 grand am GT 3.4 liter motor if u know what the problem is
please help and god bless
David Weesner: I have an 02 rendezvous. I currently have the heads off for gasket
replacement. As you know, parts are everywhere in my garage. It ran fine
before I took it apart, but im wondering if I should replace or have the
valves checked as long as I have it off. I just bought the car and have no
idea of the history. I am no expert on heads and think maybe I should take
them to a shop and have them checked? Is this just asking for a large
bill? I am pretty handy and usually go for DYI and I took it all apart no
problem. I could do the valves with good advice. I am a machinist and have
no problems following instructions. Thanks for your videos! Any thoughts
on doing what is best at this time? Car has 233k so who knows
Antwaun Robinson: About how much motor oil do I put into a bone dry 3400 engine?
meTimetraveler: the oil pump drive can leak oil, where you have to replace the "O" wring.
Symptom oil on the ground. Pooled oil under the throttle body on the lower
Albert Eble: 02 Buick Rendezvous. On occasion will start right up, grumble and then die
after about one second. Then won't start, just cranks and cranks. If I
let it sit 15 minutes or so and come back, then usually starts right up.
Runs great once running, no stalls, hesitation or other issues. Problem
only happens once in every 5 starts or so. Fuel pressure is good (58 psi).
No leakage (gas, coolant, vacuum) in engine that I can see. Any advice
what to look for next?
copcarmehanic rick: (MECHANIC 37 YRS) i work at a used car lot, everyone of those i get i
usally have to change thermostat, and int/ gaskets. sometiomes head
gaskets. make sure if u do intake, use 'upgraded' felpro gaskets(metal)
instead of plastic. its worth it.
Niko Gauna: I have an 02aztek and the coolant hoses are always hard, we have done the
water pump and the temp levels seemed more stable, we did the thermostat
next because the levels started going crazy inline somewhere sat for a long
time, or when I had it idling for a long time, 30 mins or more it would
climb, never in the red,... but still to high for my liking. It does
hesitate a little bit when u start it sometimes, other Times the remote
start goes off but don't start the car. 134, 000 on her
big bubba: have this engine in my '04 Impala. Have over 175,500 miles on it.
G. Phillips: I am having a hard time locating parts on my GM 3400 sfi engine. I do not
have diagram or manual. What is the specific name of the hose that is
connected to the PCV? Also, what is the name of the hose that is connected
on top of the air intake duct that is then connected on the back end of the
rocker arm cover? That hose in particular has a plug on the end that needs
to be replace so it can fit tightly in the cover.
MissLLP: Where is the thermostat housed?
mario villa: These engines are pice of crap no joke
Marcos Ramirez: Hi!! @ 2.35 can you tell me were that line goes, it get broken and I don't
know were to look at thank you for your video
Joshua Snyder: I have a 99 alero 3.4l. With ~162k miles. The car. died on my wife. I
pulled CEL codes. Only P0300 multiple miss fires. All cylinders receiving
spark. Will barely stay running for 1 minute. Sounds like2 cylinders
missing. I did notice the oil pressure light is on. Any suggestions would
be appreciated. I'm thinking oil pump.
John Paulson: Well I gave up on doing the work myself in fear of creating a bigger mess.
So to the shop it went. A local shop who I very much trust looked at it and
quoted me less than $700 for the intake gasket. Since I budgeted more than
that I will have him check some other items while they are there. New
thermostat and maybe some new coolant lines are in order. He said no labor
on those since we would already be in deep. Fingers crossed the overall
stays under a grand.
Victor Valencia: MY car is a pontiac grand am gt and it started knocking after i start it
and stays knock its not loud or anything and it still runs good but idk
what the knock is caused by?!! need some help!!
Oaklandcoliseum: Worst engine ever .Starts Great first in the morning but once warmed up the
engine shakes and fights it's self trying to restart after short or long
ride . Has anyone solved the warm restart problem ?
Eric Yoface: I have a 02 grand am and i noticed if i'm in park and i rev the engine a
bit, it goes from 1500 rpm then drops to 400 but it bounces to 1000 then
goes to its normal idle at 700, any thoughts on what can be causing this
issue? also idles in drive really rough like its almost bogging.
Deuce Seven: thoughts on the 3.4 in early f body camaros? degreasing these engines what
should be covered pressure wash is a no no right?
fatback1980: Hello, thanks again for the great videos. They really helped me change my
intake gaskets and head gasket. I now need to change the egr tube on my
montana. So, do you figure I can reach the nut on the manifold to loosen
the tube from below, or should I tilt the engine forward and get it from
the top? Thanks!
Fernando Warren: I have the 3400 in a Chevy venture and when I start it up in the morning it
knocks pretty bad
But once it warms up it goes away and runs fine, how can I fix this and why
is it doing this?
Charles Mcpeek: I have a 2002 Grand am gt with 3.4l.I recently lost my heat and the car
runs warmer than it it normally does.Also after this happend,when it gets
warmer it seems like it p
8goodlyfe1: Hello. The check engine light came on, scanned it, and received the codes
P0108 and P0101. I proceeded to disconnect and clean the MAF and there was
gasoline in the air intake duct, all over the maf, and the air filter. What
could have caused this and how to fix it? thank you in advance for reading
Danny Storto: My 3400 is in a 01 grand am n just the other day it started to lose power
while accelerating. Now it has NO power pasy 4000 rpms!!! Its not spark
plugs wires or the mass air flow sensor. The only code that is going off is
an oil pressure sensor. HELP!!!!!!!!!!!!!!!
oscar contreras: I have a 2004 impala and I recently discovered a bad leak under a metal
hose that runs under the 3400 upper intake manifold. It lets off a hissing
sound which I believe is an obvious sign of pressure leak from a metal
pipe. I was wondering if it was absolutely necessary to remove the intake
manifold or if it could just be disconnected and pulled off another way.
clwilu94: Someone please help. I have a 2000 grand am with this motor. Cant figure
out why it starts up but will not stay running unless i rev it . When it
gets below 500 rpms it dies. Any ideas would be appreciated.
Vacationtime247: You will need an OBD II scan gauge to pull up the codes. Any autozone or
parts store will run the codes for free. The pinging could be bad gas or
the elevation. Possibly the EGR system. The EGR system tends to get
carboned up. Change the EGR and clean the port with a coat hanger and
strong solvent. Also check for vacuum leaks with a water bottle or carb
cleaner. Be sure to check your oil too, make sure there isn't water in with
the oil indicating a bad intake manifold. Hope this helps. VT247
Elante Ford: O what might you know about the gmc Jimmy. Cause i think I need some new
battery cables any imfo on a quick fix with that please and thank you
Vacationtime247: Loosen all the 4 bolts holding on the pulley. Take off the serpentine belt.
Take out the 6-8 bolts holding on the water pump marking the mounting
location (makes re-installing the new one easier). Scrape away all the
excess gasket material on the mounting surface. Coat both sides of the
gasket with RTV black silicone. Install new water pump, install pulley,
install serpentine belt, fill radiator and overflow up with coolant. VT247
John Paulson: I'm back. My '01 Alero has 135k and seems to have an intake leak. It idles
with a very slight roughness and has a slight hesitation with slight
acceleration. A little more throttle cleans it up. Temperature wise the car
runs a little above mid-range but approaches 3/4 when in traffic. When I
shut is off I hear a hiss for a couple seconds and it sounds like it
originates from the intake bolt where coolant seeps from. Compression is in
the 140's on all 6 cylinders, so thinking intake. More to come
Mike Thexton: I did watch that video before, I forgot about it though. I remember
watching that video and thinking to myself, wow that's gonna happen to me,
I just know it. I'll check that out thanks.
CS Bens: 2000 Pontiac Grand Am w/ same engine is often stopping after 15 minutes of
driving. Wait 3 to 10 minutes it starts up and goes a while longer. When it
first happened it would go almost exactly two hours and stop. Would wait 20
minutes, make it to the 1st gas station, fill up and it was good. Now it
happens after 15 minutes and with full tank. Any thoughts? Mechanic was
Tyrone Cox: I have a 2002 Grand AM with a 3400 in it. My oil pressure like keeps coming
on. I have been trying to find out where the oil pressure sending unit is
located, but cant find it If you know can you tell me where it is located
so the I can replace it. I'll appreciate your help.
Vacationtime247: Check the fuses and check for electrical wiring going to the starter.
Perhaps the + lead for the starter relay isn't tight. VT247
Vacationtime247: Almost sounds like something coming out the vent. Perhaps a wire that has
gotten hot. But check under the hood for any fluid leaks also. Might be
something coming off the engine and burning off on the exhaust. VT247
Mike Thexton: There's never been a white wire in mine..I even cut back the tape to solder
the red one back on and it was the only wire going to the plug. There is
even 3 identical orange/red plugs from the 3 empty slots. I appreciate the
effort though! Looking at pictures of rendezvous wire harnesses on
ebay(only place I found a picture of it, I can see that the one that goes
to the alternator has only a red wire, just can't tell where it's position
is. I will just find a rendezvous around town and look
Vacationtime247: For the top alternator plug in, from front of the engine to the back
firewall, the first slot is empty, the second is where the red wire goes,
the 3rd the white wire, the fourth space is empty. LMK how it runs now that
it's all fixed. VT247
Vacationtime247: A cold air intake won't ruin anything. May give you a few extra horsepower.
But it won't affect the operating temperature at all. Does your car
overheat or the temp spike? If it stays at one certain temp (about the
middle of the temp gauge) after the car is warmed up, then it's fine. VT247
Vacationtime247: It's best to take off the upper intake and clean the passage. But, it is
possible to remove the EGR valve, 2 10mm bolts and spray carb cleaner down
the passage with a coat hanger used to break up carbon. Without taking off
the upper intake, the engine would have to eat all that junk. VT247
Richard Griese: probably 15mm. these cars are almost all 10,13,15 mm :p
John Paulson: ...I am on a very tight budget and will have to tackle this myself. I think
it worth the gamble to spend the $150 or so in parts and just do the intake
to see if it cleans up the issue of using coolant at a rate of about 1/2
gallon per month. The spark plugs all look good and I do not see any arcing
of the wires in the dark. Do you think I could get away with only doing the
intake and add a new thermostat while I am there?
Vacationtime247: Make sure the marks are lined up. Lube it up with some soap. Push the
plastic connector all the way to the end of the metal tube. If it still is
causing trouble try a small screwdriver and maneuver it in. Hope this
Vacationtime247: Yea, a gallon of gas and a match would certainly be cheaper. But I'm going
to say it's probably spark related no start. You mentioned that a wire had
to be repaired on the coil pack. Read this article. I'm betting it's in the
coil pack or the crank sensor. Just cut and paste but use a . instead of
the (dot) easyautodiagnostics(dot)com/ignition_gm/ign_module_test_1.php
Babbett Koehler: Apparently my previous comment was erased, I was saying that I have a 2003
Pontiac grand am with this same type of engine and it has been not wanting
to start. it will do fine unless I drive allot or over 60, and yesterday it
almost seemed like it was trying to die on me as I went to accelerate from
a stop sign. We have changed: spark plugs and wires, oil and filter,
thermostat, fuel filter, air filter, and the throttle position sensors. and
the serpentine belt. any ideas what else to check?
Vacationtime247: You could probably wait a while before doing the gaskets. With just 60k
miles on it, I doubt there is any problem with them yet. But around the
100k mark, they should be fixed before going out at an inconvenient time.
Vacationtime247: Rotten egg smell is usually the catalytic converter. Check the spark plugs
and ignition system as well while your in there. Hope this helps. VT247
Vacationtime247: Might be the battery is going dead. They don't last forever and will cause
a hard start if cranking slowly. If it is the cables, try a wire brush and
clean off all the corrosion. VT247
geno gomez: I have a 2000 Chevy Impala. The car is idling up and down and turning off
when I come to a stop or make a hard turn. Another forum suggested cleaning
the throttle body....
John Paulson: Oh I know I have a leaky intake gasket. There is a bolt on the head just
behind the thermostat that always has coolant around it. Oh, and the
primary cooling fan will not turn on for anything. When the AC is on the
high volume fan runs fine. I have yet to find water in the oil and have
been aware of that possibility for some time, so I check it often. Also, I
am in a very hot environment and the car has 132,000 miles on it now, so
should I consider a different grade of oil. I use high mileage.
Vacationtime247: Twist and turn the spark plug wire boot gently until it spins freely, then
pull off at the large rubber end. Sometimes they're stuck good, a set of
long needle nose grips works well. Do not pull at the thin wire, always at
the boot. If the wire pulls out from the boot it can get difficult.
Especially if the metal tab stays on the spark plug wire. VT247
Mike Thexton: Geeze, that sounds like a good time. We just picked up a Honda accord and
grand marquis both for 500. Not really having high hopes for the Honda it
was kind of a package deal, but the grand marquis looks likes it might be
in pretty good shape.
