Robert Smith: Have you ever heard of cracked heads with certain GM 5.3 heads. I have an
05 that appears to have coolant in the oil.
Gary Sullivan: We have a fleet of Chevrolet and gmc trucks at work, approx.50 to 60.We had
a problem with lifters tapping even when new, we changed from the
recommended 5w-30 to 10w-30, because the 5w30 was just too thin.haven't had
any problems since, this was only on the first generations of 5.3 and 6.0
motors up to 2005 or so
Rick Nelson: I followed these instructions and found about 8 of the tube clogged up so I
think my truck would fit in under this repair umbrella. Hope to figure out
why I have no pressure upon reinstall. Only thing I can think of would be
the O-ring replacement but I had eyes on the tube and plate when tightening
it down. All looked good, no O-ring pinched and hanging out. Lots of gunk
in the pan.
Joe Johnson: I never liked motor flushes because it can create oil leaks and do damage.
You are doing unnecessary work. Change the oil and add a pint of Marvels
Mystery oil and change the oil in 500 miles again. In less than 500 miles
the noise will go away unless the lifter or cam is worn. Changing the oil
and substituting one quart of ATF works also.
jacob classified: i have used seafoam in carbs to clean them and it works great for motor
cycle and atvs. simply drain the carb fill it with pure seafoam and let it
sit over night. then drain the sea foam out filter it back into the tank.
and have it run through the jets 9 times out of 10 i don't have to remove
the carb. it also will clean the head out. something other brands say they
do but dont. i run it every other tank for every engine i have. they run
great and keeps them clean and fuel efficient.
David Shields: Just had the exact same problem about 2 weeks ago, same engine. I poured a
bottle of sea foam in the engine and before I made it home from the auto
parts store(about 5 miles) the noise completely went away and she was
running normal again. I flushed the oil twice a couple days after.
Don N: I have had the same problem with 5.3's Camshaft time. One cam lobe is worn
down and the underside of the lifter is hollowed out.
Next time put the piston as close to top dead center as possible and then
wiggle the rocker arms. You will see there is way to much valve lash. When
you took the push rod out the lifter pumped up as they call it. When you
ran the engine after,it was quiet for a while until the lifter re centered
itself. Then the noise comes back.
HEAVYGUNZ05: After doing this should I go with a heavier weight oil
Rick Nelson: Just did the Gunk flush, push rod clean up along with the valve covers. Pan
off, new O-ring for the pick up tube etc. Buttoned it all up and fired the
truck up. No pressure. Had good pressure prior to flush. What could it be
and how do I troubleshoot?
2000 Chevy 5.3 with lots of miles. Everything else looked good.
SteveXnycperformance: The first think you should do is, Install a oil pressure gage at above the
oil filter on the block(or see Shop manual). Make sure the oil pressure
meet the factory required oil pressure at idle and operation temperature.
Before you remove anything, Dis-connect the battery. At that mileage it
time replace the timing set and front driven oil pump. The new oil pump
will eliminate the lifer knock
Sickofit: Has anyone ever considered replacing the lifters? That trick has always
worked for me on other engines in the past! The new Chevy V8's are sooo
easy to work on, I love them!
ben64911: Just came across you're channel about 1 week ago. I have to say you make
the best videos by far mate. Keep up the good work :)
mark lemos: I did motor flush changed oil upgraded from conventional to synthetic blend
and added rislone. The tapping went away, car even ran better. Two weeks
passed and the tap is back and louder. Now getting misfire on 5 which is
where I used a stethoscope to pin point where the tap is coming from. Any
suggestions as to what I can do next. also, It's not a dirty or
un kept engine I keep the car maintained well...

William Atkins: great video guy!!!!! Just what I needed for my 2004 Tahoe this
weekend!!!!!! I'll be performing this job on Sat. morning.........this will
save me a lot of time and money hopefully!!!!
Piotr Tester: Try this product Wynn's hydraulic valve lifter treatment
jim davidson: Rislone would of cured this one. Ask your grandfather all about it.
JR Reed: Behind all the shenanigans there is some great tech in these videos! I'd
love to get dirty wrenching on something with this guy lol. Thumbs up for a
Benice Ryan Balague: Use Amsoil products. It will be better for your maintenance needs
especially doing engine flushes. =)
Misty Buffum: Hmmm doesn't seem he answers questions but only post videos, is it true? I
keep finding videos like this but none that are helping answer issues.
crackermoves: ANYONE with lifter noise or ticking add 1 or 2 quarts of Transmission fluid
in place of 2 quarts of oil and put 300 miles on it.. It works WONDERS..
Cleans all hydraulic lifter journals and turns of check engine lights to...
Its amazing.. ATF is a lubricant so will not hurt your motor but is high
ArmaAceChannel: brian have you ever had sex in a car?
tibbysteve: Hey Brian. This is Steve. You met me and my wife when your dog was on the
loose or so we thought in Starcrest drive. Anyways. I was hoping you could
help me one day identity the noise my 03 tiburon gtv6 is making. I'm trying
to sell it for a low price of 2,000 bucks but in the last 6 years I'm into
the car 20,000+ please help. Thanks neighbor. And how's your doggy doing we
loved her. She was a great minding dog.
Robby VanWagoner: That ticking noise is from the metal on the lifters roller starting to get
pitted. No solution will make it go away until you replace the worn parts.
Left untreated it will eventually flatten the camshaft lobe and cause a

Evan Austin: Hey brian, I got a 99 with a 5.3 and well I went mud ridin (yes I know a
big no no) and we'll when I went to clean the truck off and engine bay, my
engine started to tick just like this truck in your vid, it was showing no
oil pressure on gauge and I put a quart of oil and now it's normal but I
didn't start the truck to see if it continues to tick, also my engine is
needing a oil change also, could be oil needs to be change and motor flush?
No oil leaks that I notice or cracks or anything? Just started ticking
after cleaning engine bay off? Any tips/advice ???
snowy800123: my 97 chev 1500 has that noise..
lat woods: Damn I love my DOHC and SOHC engines (2005 Nissan Altima 2.5L cyl 235,000
miles no problems, 2007 Toyota Tacoma Prerunner reg cab 2.7L 4cyl 147,000
miles no problems, 2011 Toyota 4Runner 4.0L V6 78,000 miles, and my 1994
Ford Ranger 2.3L 4cyl, SOHC 351,484 miles no problems) no lifters,
pushrods, or rocker arms.
Netruckcap: Had exact same issue, think about it on all these videos it's always the #1
and 2 cylinders make the tick noise. The O-ring on oil pick-up tube is
going bad. They get dried out over time and start to break down this causes
oil to suck air into pump and decreases pressure to front two cyniders. I
tried all the tricks shown on YouTube, none worked then I finally lost all
pressure. I changed the pump and the noise was back, then I changed the
O-ring on the pick-up tube. When I changed the pump only I must have seated
the O-ring better than it was but it was still bad. Hasn't made a tick
since and my oil psi is back where it should be. Save your self the time
and money, get a new O-ring for the pickup tube, which it think comes in
the lower pan gasket set and change it.
Anthony L: Google bulletin #06-06-01-019B (a lot of good info there)
Barnekkid: Why do you think seafoam is so good?
Steve Mayer: Where can I get me some of that there diesel gas?
Lion85X: I had the same thing happen to my truck, but I put half a can of seafoam in
it and drove it for a hundred miles and did a oil change and that stuff
really worked great. It was running smoother, quieter, and there was a lot
less crank time.
NYRM1974: I have a 5.3L Vortec on my 04 Chevy Trailblazer. What I do is bring the
engine to operating temperature. Then I check to make sure that the oil is
to level. Then I pour Marvel Mystery oil run for about 4 minutes. Drain
crankcase ..... because I am using synthetic oil, I add one quart of Lucas
oil treatment and the remainder of quality brand synthetic oil.
I have been doing this on my Trailblazer Ext LS and it runs great. I drop
my oil every 4000 miles.
Adam Rupert: Love your vids....question for ya, on a 08 Tahoe, 5.3, got what looks like
a collapsed lifter on #6. I've watched your video on replacing the intake
gasket and was curious if you could suggest how and what needs removing to
get to the lifters? Valley pan? Cylinder head?...thanks for any
Earl Guyton: Master mechanic here 44 yrs experience. First off let me say I like the
man in the video, I like his attitude. But here is my first analysis from
the start of the vid is OIL PRESSURE, next after that valve cover was
removed I saw NO OIL laying in the upper cupped area of the rockers!
Meaning the rockers aren't getting oil and of course the lifters cannot get
oil either being no oil gets to the top in order to drain down! The sound
I also heard at the vid start was not lifter noise but rocker tappet
noise. That engine is not getting upper oil! Oil pump issue here! Thanks
Michael Burman: I have a 2007 Chevy Avalanche....can you do a video on how to actually
replace the lifters?
q8single: yes I know that sound its oil pump change it before it break your engine
HUBBABUBBA DOOPYDOOP: Lifter cleaning: Use the pushrod as a "straw" to *directly inject* the
cleaning fluid, AND to *push the lifter down to work it*, pumping the
cleaner through it. IMO K1 Clear Kerosene is a great "flushing" fluid;
drain 2 QTS oil, replace with same amount of K1 CLEAR Kerosene (not the
cheap pink colored). Also- to check for a bent pushrod- clean, then roll
them slowly by hand on a piece of quality window glass. *OLD SCHOOL STUFF.*
burtonkidd: Thank god my lifter noise isn't that loud, the ever so slight tick i have
on my 5.3 drives me nuts when i have the window down at a light.
Would it be alright to go to lets say 5w 40 instead of the recommended 5w
30 to reduce some tick or would they be the same viscosity when at
cam94z28: If it is actually a lifter tick, as in, it' usually worse when cold, and
quiets down somewhat, or completely once warm. I have 3 words for
you....MARVEL Mystery Oil! I have a 95k LS1 Camaro. It had a fairly
terrible lifter tick on cold startup, which would continue for at least
several minutes. Sometimes still ticking when halfway to work. I added a
quart of Marvel, in place of one quart of oil, at my last oil change. Each
time I started it, it was a little better. Within about 3 days of normal,
short-trip driving, the tick completely went away, and hasn't come back
over the entire oil change. I will be using it at every oil change in this
car, and occasionally in vehicles that aren't ticking.
Joe Galofaro: alright this helped ALOT, BUT I HAVE A QUESTION SOMEBODY GIVE ME SOME
ADVICE, i have a few years experience as a tech in a small shop in a small
town and im not being a douche but im not bad for a teenager, but when it
comes down to brass tax you cant triumph experience, so my step dad has an
2008 Chevy Tahoe with 210xxx miles! he takes long driving trips in it, been
an AMAZING TRUCK, never touched the front end, never had ANY motor problems
till now, very small lifter or somekinda tick, very faint but multiple
ticks are coming too. should i even bother getting into this and tearing
down heads? or just run some 0w30 syntec then flush or just flush or what?
i dont have access to a shop anymore since ive switched professions into
the military, but i can still do it in a friends garage, help?? PLEASE!?
XboobtubeX: so after the 5 min. of idle running for the motor flush, I take it you
drain it out and replace it with fresh oil????
hddm3: cant fix stupied brian
Standard Excellence: I love how you explain things. And you answer some of the 'dumb questions'
that people who are probably watching wouldn't know to ask instead of just
assuming everyone knows. :)
gary mathews: also roller the push rods to check for straightness.check the rocker arms
for missing bearings .
Jose Arellano: does that noise go away once the engine is all warmed up? i hear something
similar in my 03 tahoe but it goes away when it is warmed up. it is more
noticeable in the mornings specially if its cold
fordsucks2: Great Video. 5 stars
Tom Schroeder: So my truck, 2000 Silverado 1500 5.3, sounds just like this for the first
couple minutes or so of start up, depending on how cold it is, is this
likely my problem?
DavidsCarReviews: My dad has the same problem on his 05 chevy Tahoe and it gets worse I'm
lucky is not happening to my 13 tahoe but I'm gonna fix it for him but it's
a lot of money to get a waterpump
