The GM 5.3 and 6.0 are well known for this clicking (usually caused by clogged lifters even on engines that were babied from day one) the piston slap is an issue with the pistons rocking because of the different metal types used in the 5.3 and 6.0 once warmed up it fades as the pistons expand and fit the bores better over time the clicking will last longer and sometimes get more prominent (ive herd these engines sound like diesels and still run like champs) like alot of newer GM engines these are very sensitive to coaking (cooking oil in some spots) so doing oil changes at shorter intervals may help with this issue (this info is based of the 1000 truck fleet i service regularly and other customers vehicles equipped with said engines
There is no additive that can cure piston slap, and there never will be. Piston slap means the cylinder is larger than the piston and the piston has play side to side. Unless "seafoam" can put the metal back in the cylinder, that isn't what fixed it, or it wasn't piston slap.
M Bro the 6.0 are bad to get piston slap, the skirt's on the Pistons are shortened to get more stroke but caused them to get the slap. Once the Pistons warm up, boom the sounds gone
Yeah, this youtube seafoam stuff is getting pretty silly. They don't even know whats in it. Its a 2 stoke motor boat lube created in 1932. Marketed for suckers.
It's not piston slap or a stuck lifter. These are know for the lifters to clog up and make that noise or get low oil pressure from a bad oil pickup tube o-ring
@@dskrpncs Fuel tank, oil sump, or let it TRICKLE into the intake charge tube via a vacuum port. If you're going for a vacuum port be careful not to allow too much to get sucked up if you've got an engine with a small squish area above the piston... you might bend a rod.
Do a oil change and Put 1qt of RISLONE in it with a oil change of royal purple or mobile 1 and with a ac delco or mobile 1 oil filter and drive untill 3,000 and change it 2 times like that and it will help clean your engine and completely stop your lifter noise.. It did for me in a 2005 chevy tahoe LT with 205,000 miles
Did you put it into your oil or the spray through the vacuum? My 6.0 has the same problem. I put sea foam into my oil and it quieted down some but still pretty loud.
I think what the seafoam cleaned was the hollow rod on your lifter, but no engine pro here. Trans fluid 50 miles before an oil change should do the same thing.
That's your valve springs bud, Vortec engines are common for these issues same with the Hemi. I have a 2012 5.3L with 280,000 KMS and same issue. My 2004 Z71 crewcab has the same issue. It's nothing bad, nothing to worry about.
That sound was NOT piston slap, that was a tick, Slap has a distinctive hollow "conking" sound that you can hear on all 8 cylinders. No wonder Seafoam cleared it, it wasn't slap to begin with.
seam foam only cleans out carbon build up, def doesn't help quiet the problem down, the only reason it quieted down was because you took it for a drive and allowed the engine to heat up, therefor the piston expanded (because aluminum expands when warm) and BOOM no more piston slap
I had the same problem on my 06 crew cab Z71. I tried all the motor flushes that I seen on previous UA-cam channels. It’s seem to go away just a little bit but would come back it got louder and louder. After doing tons of research and learning about the GM piston slap. It is due to the cast iron block and the oversize skirts on the Pistons that will tap until the truck is heated up. This was not the case in my truck. I ended up calling and putting new LS seven a listers new lift her tray and new pushrods. I have drove it now for over 40,000 miles and zero sound. I also noticed before I done the work on it my all pressure would hardly get up to 40 pounds only if I was deep into the gas pedal. Now since the works been done I can barely tap it in my old gauge will get up over 40 every time I’m dealing with a front differential problem now after the truck being lifted. Also the slapping under the dash is the intermediate steering shaft had to change that as well. That should have been covered under GM as well. Seems they are only building for looks now not durability and sound lol
Seafoam works. Period. For the right applications, anyhow... I never believed in any "mechanic in a can" stuff until I saw it work. We have used it in several industrial engines (Caterpillar G3306, G379, G398). We had serious crankcase venting issues on the G398. The seafoam freed up the rings enough that the crankcase vapor venting was back at an acceptable level. We have also used it to free up sticking valves in the G3306 and G379. The valves were sticking bad enough the units were shutting down manifold vacuum safeties and routinely backfiring. They would not reliably carry load. Now buying enough Seafoam for a 100 gallon oil sump is kind of expensive, but way cheaper than a head swap or pulling pistons and liners. It has bought us time to plan outages. It works.
Typical Chevy for you. I do agree with the frame filter comment. K&n makes pretty good oil filters. 1000 miles on my oil with a k&n and my oil still clear like it was new plus better oil pressure.
That's called lifter knock not piston slap, running a strong detergent in the oil or spraying brake clean down the push rods before an oil change (preferred method)will help clear it up. Piston slap can only be cured by boring the cylinders to fit a larger piston.
i have a 2002 avalanche z71 and I have stage 3 ported and polished heads from promaxx but anyways it doesn't matter if its hot or cold it makes a knock sound for like 5 mins than it goes away so I don't think its piston slap plus its coming from the exhaust so I think its noisy valves
yea we see that alot in my dealership throw some top engine cleaner in it and it goes away, theres a bulletin that blames carbon building up on the sides of the pistons or in the combustion chamber it causes slight spark knock at idle or the noise you hear is the carbon breaking up, top tier fuel would probably help too
hey guys if you have a Chevy Silverado with this issue like I did and sea foam doesn't work for you do a engine flush and put engine restore in your motor oil I swear by this stuff I tried all kinds of things to clean my motor and nothing worked but after 5 minutes of engine restore no more noises in a smooth running truck I hope this helps some of you who are dealing with this issue!!!
Ignore the ignorant internet hype and read the MSDS for chemical contents. There is no way seafoam will fix anything. May even cause problems. Pale oil, Naphtha, and Isopropyl alcohol belong in a fishing boat or lawn mower, not your modern auto engine.
that noise is a collapsed lifter that will eventually lift when you get 200 degrees or so. any 2-weight oil will do that, fix the lifter for a short while, but it will stick when it gets cold again. using STP oil treatment will also make a lifter shut up long enough to sell the car.
Alex B Exactly, which is why there was no piston noise heard. Seafoam will not cure piston slap, it will not reduce piston to cylinder wall tolerance which is what causes piston slap.
Piston rings have nothing to do with piston slap. Piston slap is the piston itself moving in the cylinder. I've heard it in just about all years, and not limited to GM. Toyota 3.5 is also notorious for this. It's a result of short piston skirts which reduces weight and drag, but lets the piston rock in the cylinder until it expands as it warms up. It's harmless.......
mrpotatoheadracing. This makes perfect sense. Question tho : we've got a 2006 GMC Denali 6.0. it now has 195,000. at 100,000 miles I never heard it knock like this truck does BUT at 170,000, yes , when cold it knocks as this truck in the video now. so what I'm basically asking is, why did it not sound that way before. I was running synthetic 5 w 30 & now have begun to add STP oil treatment & full synthetic 5 w 30. it's helped some but that knock at cold tho....Grrrrrrrr. I run 93 octane. I don't know bud. just figured I'd ask. My ears always on the ground listening for knowledge so if ya git a chance, thanks for any advice in advance.
do you know why he didnt hear the noise as loud after taking that short drive...? engine temps.... my piston slap in my honda gets lessened with the increase of engine temperature, and it fully stops when the engine is warmed up.. Seafoam had nothing to do with the decrease in engine noise after a short drive.. not ragging on seafoam. i use it in my motorcycles. but its not going to stop Piston slap...
Dumb video, he didn't say where he put the seafoam and after the engine reaches operating temperature the knock stops anyway. At least on my engine anyway.
Uhhhh. Didn't GM shorten the skirt on all the vortech and LS engines? I've seen these engines start the click at 10 or 20k miles and last to over 300k so I wouldn't call it an issue. Put a louder exhaust on if the click bothers you.
Guess that's why most GM v8 engines have less bearing wear. Less rotating weight on the bearings. Lot of different factors there. If they would have put a better lifter in them they would be almost bulletproof. As long as you keep the oil changed it will last. I think the newer VVT engines are having oil consumption problems from day one.
Ive had piston slap in my 04 since i got it in 2010 with 100k seafoamed it yesterday & the slap is almost gone only does for a few seconds on cold starts
I have same engine. Had same exact noise in same exact spot. It was identical to this sound. I used seafoam in the gas tank and brake booster vacuum line and now no noise. Still quiet. I was surprised by it. Mine don't make noise cold either. Only did it when fully warmed up. So glad it's gone. Noise got on my nerves. Some people say the 5.3's and 6.0's all have cold piston slap when cold then goes away warm but like I said. Mine don't do that. I guess the guys with that problem there engine was built on a Friday...lol. I'd try some Seafoam. My sisters car had a ticking engine and we put some marvel mystery oil in the oil crank case and a few miles of driving around it cleared up. Sometimes simple things work, sometimes not.
Yeah everyone of these videos I’ve watched with the lifters tapping has had one of those freaking Fram filters on it AC Delco or Purolator filters are the best
I had this same sound on my 350p express! And guess what the fuck it was!? The flex plate was crack all the way around the bolts. This made a ticking sound with no load. Accelerating makes the ticking stop.
Just so peeps know, piston slap sounds worst when engine is cold but mostly goes away when she warms up. Putting SF in the intake would have ZERO ZILCH NADA effect on PS. Dont waste yer money. GM went bankrupt to avoid fixing these motors. The ONLY fix is an engine overhaul. That being said I have a 2001 2500 suburban with 130k miles and bad PS when cold. She runs fine, dunno if I’ll get 400k like some vortecs but bottom line is there IS NO EASY FIX.
I bought a nice C5 Corvette of this era and it's a "slappa" after I sold my Honda S2000. I love GM and will always have a place for them, but the reality is the quality of the build of these cars is just not great. You'd NEVER see this on a Japan assembled Acura or Honda. It's just a crying shame the quality is just not there.
You see it on Hondas, Acuras and Kias just snap. You have junk in every brand Just people don't want to talk they bought a piece of crap honda. They trade it in.
thats not piston slap thats most likely a lifter if piston slap was happening ur bearing shot on your crank what that prohibites is lash/play and your connecting rod is moving and scraping the side of your cylinder or you heads been grounded down and your pistons hiting your valves.
what the heck are u talking about?? If pistons hit the valves motor will no longer run. The rods never hit the side of a cylinder. Not without putting a big hole in the block Thats called catastrophic engine failure.
you can still run with piston slap but its vary hard on your motor. you can run with a rob knocking but you'd hear it. go to a durby and you'll hear rod knocking from at least one at some point but 7 out of 10 times the motor will lock first. as for the valves being bent thats under full force but you can run a motor with slightly bent valves.
and the Seafoam is petroleum baded so it probably cleaned the gum and varnish from the lifters and they are pumping up fully now. You gonna trust your vehicle to a 3 dollar piece of crap? SMH.
This is funny. I came across this on accident. However piston slap means you unfortunately got a block that has piston slap. It will wear out the block faster than other 6.0l That do not have this reciprocating disorder. Their are blogs on this. Sorry dude. By the way I have a 2000 chevy ls 6.0l silverado with 175,000 miles and no such knock. Although I clean my valve rockers now and again.
oi most people who drive the 6 use cheap gas which makes it tick some do some dont but most of them tick with gay cheap gas so put in better gas it wont click as much THE END ::))
I did everything to my chevy.. Until I dropped the transmission.. Flex plate was cracked.. Also watched every video on the jewishtube didn't help.. Pure bullshit
cuz it actually has shown to work. you put this product in your gas tank and it goes through your lines into your injectors, cleans your injectors and intake manifold. this product makes your engine run more efficient. although a real engine rebuild is a whole lot better

Wait, so if the reason for clunking is the piston material and size, how is it “usually caused by lifters”?
StasKatia Bakanov it's both. My 5.3 does both. They are separate issues. The piston slap goes away after warmup. Lifter tick does not.

Yep mone has 330 on her and I legit am picking her up from the shop today just had the o-ring replaced
Thanks for this. I'm at 60000 miles and counting with the noise. It started at around a 100000. I always let it stop before driving.
That wasn't piston slap. Sounds more of a stuck lifter
i was thinking that too, if it was piston slap it wont go away stuck lifters will go away
@@redneckasmr-xd1gg mine is the same way I hear the noise coming from the bottom but goes away when its warm

My '77 caddy with 80K 7.0 slaps, and has lifter knock for a couple minutes after a cold start. Can barely hear it running after 5 minutes.
seafoam sometimes breaks down the shit in your gas tank and ends up clogging your fuel pump/filter
Because gasoline is never used to break down gunk?

Bondo agreed. It is nothing but snake oil.
take that junk ass Fram filter off it and use. Wix or AC DELCO filters. That's the worst filter out there.
royal purple filter is better
Pretty much any filter other than Fram would be better. The metal casing on the Frams are crazy thin.
Been using Fram for over 30 yrs and never ever had a failure. All my vehicles go to the bone yard rotted out with 300,000+ on them.
You have any scientific proof to back up what you say?
I use coffee filters wrapped around a tampon stuffed into a red Solo cup for my oil filters 👍

you can still run with piston slap but its vary hard on your motor. you can run with a rob knocking but you'd hear it. go to a durby and you'll hear rod knocking from at least one at some point but 7 out of 10 times the motor will lock first. as for the valves being bent thats under full force but you can run a motor with slightly bent valves.
strikeforce4 piston slap doesn’t mean anything bad. These motors do it all the time.
anyone else wait.for the oil droo
its a broken or breaking valve spring
Nice speedo (;
Mine runs just fine i just got use to the noise
So between the piston slap of the chevys and the spark plug issues with the ford i'd say they are both junk. But i would lean toward getting the ford.
My 6.0 has 340k and does same thing at idle.
Any issues?
fix the oil leak you ran it without oil now you have a stuck lifter
يا انه زاحف شف الطبلون 100 ميل
Hahahaaha seafoam fixed piston slap lmfao
and the Seafoam is petroleum baded so it probably cleaned the gum and varnish from the lifters and they are pumping up fully now. You gonna trust your vehicle to a 3 dollar piece of crap? SMH.
That’s a stuck lifter. Not piston slap
that wasn't piston slap, seafoam wont fix a worn piston or cylinder what seafoam does is remove carbon.
Its not mechanically possible to solve piston slap sucking in a fluid.
mechanic in a can fixes piston slap bitch please
Larry Brasher JR lmfao
This is funny. I came across this on accident. However piston slap means you unfortunately got a block that has piston slap. It will wear out the block faster than other 6.0l That do not have this reciprocating disorder. Their are blogs on this. Sorry dude. By the way I have a 2000 chevy ls 6.0l silverado with 175,000 miles and no such knock. Although I clean my valve rockers now and again.
oi
most people who drive the 6 use cheap gas which makes it tick some do some dont
but most of them tick with gay cheap gas so put in better gas it wont click as much

lol learned nothing from this vid.
Lmbo
Sounds like a loose timing chain
This is pure bullshit. Unbelievable
I think you did it wrong
god dam all gm engines leak oil wtf
+ArmaAceChannel Are you talking about the oil around the filter?
Use AC DELCO or WIX filter.
I did everything to my chevy.. Until I dropped the transmission.. Flex plate was cracked.. Also watched every video on the jewishtube didn't help.. Pure bullshit
wow.....engine rebuild in a can!!!!NOT......why do people buy these gimmicks.....??!!
cuz it actually has shown to work. you put this product in your gas tank and it goes through your lines into your injectors, cleans your injectors and intake manifold. this product makes your engine run more efficient. although a real engine rebuild is a whole lot better
only cvrap i put in my gas tank is b12. every month to clean my fuel lines and injectors not to mention the added mpg i got off it
Czrap??????
