AssGrabber B: Awesome buddy thank you!!!
MusiikN0w: hi brian love all your videos, have a question i have an 01 silverado with
the 4.8 vortec with 166k miles and the lifters seems to have some clatter
or shutter when it warms up. i have great oil pressure and it runs really
well and doesnt smoke at all, is there anything i can try to do? since ive
owned it ive changed the oil every 3-4k miles and ive done a sea foam
Bruce Banner: Lucas engine flush does the same thing?
Michael Winn: Thanks for the educational video Unfortunately my 2003 Chevy Avalanche has
this same problem. Mechanic diagnosed problem by sound. Recommended
replacing all 16 lifters. $2,150 to replace Question: Should the lifters
first be visually inspected and then determine whether they can be cleaned
vs. replacing? Thanks for your time.
GINA O.: my 2001 tahoe sounds jus like that only at morning start.my mecanic says
its fine? well looks like i will be doing the old motor flush!thanx for
Karl Portner: Great video, but beware of this:
Bulletin No.: 04-06-01-029E: "General Motors Corporation does not endorse
or recommend engine crankcase flushing for any of its gasoline engines.
Analysis of some of the aftermarket materials used for crankcase flushing
indicate incompatibility with GM engine components and the potential for
damage to some engine seals and bearings. Damage to engine components
resulting from crankcase flushing IS NOT COVERED under the terms of the New
cam94z28: Have you ever had a motor fail after running a harsh flush like the gunk
through it? You are bold if you ran it through a 180k mile engine :P
Steven Mitchell: the 5.3 suffers from cam issues
autoworld100: Good work!
Russell Booth: One thing to note on an LS1 motor or any engine with oil gallery plugs is
to remove them first before draining the oil if there is a lifter noise,I
removed the one from the left hand rear of the engine block a few weeks
AFTER I did the oil change & engine flush because the lifter noise came
back a fortnight after,actually I did it mid this week and I have driven
the car for over 300 kilometres in the past 2 days (about 200 miles) and
the noise hasn't come back.All this sludge & some metal shavings (probably
from a camshaft lobe) came out with the oil from the top oil galleries and
I don't think any of that should've been there past the oil filter and I
don't know how the metal shavings got there.So an engine flush doesn't
necessarily get all of the crap out of the engine ,in one go at least
therefore you would have to do what I mentioned, a couple of flushes or in
the worst case scenario an engine rebuild is in order as the problem will
only come back if it's not caused by a failed lifter.I heard of a person in
the 1960's who had that problem with a Ford Falcon in Australia and it was
meant to be caused by the brand of oil used,the engine was stripped down,
the engine block,etc was hot tanked then reassembled and never used that
brand of oil again with no future problems.The oil galleries must be clear
& clean, I know of someone who lost a rebuilt 351 Cleveland engine because
the machine shop didn't clean the metal shavings out of the engine from the
boring process,he drove down the road for a few minutes & seized the engine
up, so the oil galleries must be clear & clean.
Janet Hoppe: I have 2002 Xterra with 272000 miles and runs well. My question is would I
be walking into a danger zone by doing an engine flush on this thing. I
bought it for a couple of hundred bucks and have no idea how well it was
maintained. I have been changing oil every couple thousand miles trying to
get the oil cleaner, since that is the only thing that looked dirty when I
got it. Thanks for you suggestions.
Dan P: Hmm, I think it was easier adding 1/2 cup of ATF fluid to my oil and
driving 2,000 miles until the noise was gone. The tick had previously
persisted for over a year and 40K miles.
Bigninjon: Yes winning lol
by any means racing: just wondering why you didnt check oil pressure before you did all this
work maybe you did and i missed it . also gm 5.3 with active fuel
management has a filter underneath the oil pressure switch that feeds oil
to 8 lifter and has a tendency to clog and cause clatter sometimes it needs
to be cleaned just saying . nice video
D. Owen: and AGAIN, I've learned some more great stuff on youtube today!! Thanks!!
Sean Craig: This guy is awesome I wish I was half as happy as you
Chris Wheeler: Dude your a bad ass! You know your stuff. My 2000 silverado is doing the
same thing. Could I try just putting sea foam in the oil right before I
change it and possibly clear it out?
heettreet: oil does not look aged as it did 50 yrs ago ,,,, no lead in gas
Austin Craig: I think ol walter jr was doing a little bit too many burnouts...
Chris Hamer-Hodges: about to buy a 99' jeep cherokee 4.7 v8 with a ticking just like this.
could this be the same issue? could it be something else? is it worth
buying this car for $400?
Phillip Creoruska: You got while spraying the top of the lifters. One of the funniest
reactions I seen in a while.
Mark Doe: DORK
Mike Hartmann: I just had a collapsed lifter replaced in my Chevy 5.3 with only 6k miles
on the clock. Actually two lifters replaced, as GM said the opposing
cylinder lifter had to be replaced too. Great that this was 100% warranty,
sucks that it happened at all.
XbenX0101: lmao great video man
carwasher420: Hey Brian, I'm gonna give it a shot, on my 2005 5.3. Same crap. I watched
your video like 4 times I pretty much got it down,, my only question is,,,
when I put the rod and rocker back, do I just tighten all the play out, or
do I have to tighten and follow the fireing order?? And do top dead center
and all the procedure?? So far only helpfull video on you tube.. Thanks
Shiftin Gearz: Ive read lifters cam oil pump etc. High milege engines with tappet noise
may be caused by low oil pressure(ez test) caused not only by oil pump but
more often crank bearing wear will prevent the pump to get oil to top of
engine. Im sure we all know this. Peace
rogbri1971: I want to thank you for all your videos, I am going to try this on my tahoe
since I have the same problem. BTW, you saved my volvo xc90 twice! Thanks
briansmobile1: It's worth a try and sure beats doing nothing. Also Diesel fuel helps
loosen them up. When I have a stuck lifter out like on a head gasket job I
soak them in DF over night.
RICKAFIX: Hey Brian Great vid as always. I am going to have to do this to my 204k
tahoe but for some reason i want to reduce my shopvac hose down from a 2"
tube to 1/4 tube and when the lifters are soaking for awhile put the 1/4"
tube on top of the lifter stem and suck the grim out of there. and maybe
blow some air down the to clean the bottom half. Think that would work?
Toluene: Not worth it to me. obviously you can add seafoam. Seafoam you can drive
with, the motor flush you can't. Some pans you can't drop without pulling
the engine and even if you can just pull the pan, it's more of a pain the
not having to do it at all (there will be other things in the way that have
to be removed). When your engine really starts to go and you need a
rebuild, that's when you clean your engine. Unless there's tons of sludge
and buildup, there's really no reason to worry about it.
Toluene: If it's just after you start it when it's cold and goes away it's nothing.
GM has a technical service bulletin about this and says it's fine. how long
does it take before it stops ticking?
Toluene: They don't know what they are talking about. Find a new mechanic. you don't
need to change the cam to replace the lifter. The cam rarely goes bad and
you would have more than just a tick if it was. Any decent mechanic would
Warren Bradely: I wasn't talking about the motor flush - on that you are correct - I was
referring to the b-12 he was using.A small amout to free up a lifter is not
going to affect seals...No big deal.
Jason Breakfield: I tried this on my yukon that had the "click"-assuming it was a stuck
lifter. It is still ticking but not quite as loud...any other ideas to try?
Earl Guyton: Master mechanic here. This video is all wrong. The valve cover never needed
to be removed at all, because this engine isn't getting upper oil which is
the OIL PUMP! The oil pump needs to be replaced. I like this guy in the
video but I think he is a salesman and not a mechanic.
TheJsmith BA: Ford 4.2 Coil pack is all-in-one on top of engine. even better.
Warren Bradely: It is a matter of opinion if it is intensive to replace lifters...As soon
as you crank that engine the oil wil remove all of the chemtool..if a
higher viscosity oil will not cure a stuck lifter - this video is a good
fix - if you think replacing lifters is hard this video is a good fix..It
is not, however, so quit splitting hairs with me.
Toluene: I wouldn't use it because there is the possibility of corrosion and reduced
life of the lifter if it isn't already bad. Whether that fixes it or not,
it's just a band-aid till it comes back whereas if you just replace them,
you know you would be good. It isn't that intensive to change them.
rob quimby: I have a 2006 crew cab chevy 1500 4.8L V8 that makes that same knocking
noise but only for a few minutes, and on the first time I crank it. I have
used seafoam and waited a few days and changed the oil and then hoped that
would fix it but it didnt. im no machanic but would my nest step be to do
what you just did to this truck?? or what would you recommend
Tony G: so, did you torque the rocker arms to the valve spring and check the
clearance between rocker arm and valve?
tommy David: I tryed this no luck still making the noise help! !!!please
briansmobile1: Poor spark plug type for the application and or gas that is lower octane
than vehicle threshold.
lokslick: You sir just save me a bunch of money they try to charge me $2,500 to get
my 03 Chevy fixed but now thanks God I found this video and thank you for
taking the time to show people how to do this kind of things again thanks a
LEO TERAN: excelente amigo gracias,
pablocruisefromsocal: Brian, Thank you for sharing this info. A lifter in my 01 Silverado 4.8
started ticking badly like inthe video. I took off the coil pack plate and
the v/c but then reconnected the coils. I started the engine. The #5 intake
lifter wasn't pumping up apparantly. I didn't remove the rocker but did
shoot B12 down its bleed hole. I also shot compressed air into it. I let it
soak for a bit and also added 1/2 qt of ATF to the oil. I also added a
little bit an STP additive that claims to quiet lifters
ericspeeder20226789: Question.. my 98yucon makes the same noice I had the header gaskets and
heads replaced after that I was left with the low ticking sound just like
the truck in this vedio.. my question is wuld a bad riser cause the truck 2
shake and low cylinder presure? I was told my cylinder rings were busted
but im starting 2 question that..
califcheesehead: I noticed this same sound in my 2006 GMC Yukon XL 5.3 1500. At first it was
very faint and I was going to take it to the mechanic at the end of the
week but in the period of a few days it became not quuite as loud as it is
in your video. I took it in this morning and they told me it was the
harmonic balancer changed it and the sound was still there. They say it is
a bad lifter and gave me a quote of 3300 to replace the cam or 6000 to
replace the engine if the engine was damaged. Any feedback?
mhockey23: Same thing happened on my '08 silverado. Wish I could've fixed this myself;
winded up costing me $4100!
briansmobile1: Experience..... That's tough to share verbally. I guess that's why torques
William Eldridge: I'm having a problem with my '99 Tahoe w/5.7. Had the oil changed 2 weeks
ago (and there was a lot of sludge in the old filter!) Went with Castrol
Synthetic 5w30 and K&N filter. Drove to TN and back last week, now the
truck is making that same ticking sound AND has very low oil pressure! It
only has 138K miles, and did have decent oil pressure before. Any thoughts??
