LedHed65: I have a 98 Blazer with the 4.3 It knocks at start up for a few seconds then goes away. Ive been changing the oil about every 1000 miles for the last 3 or 4 oil changes and it stays quiet for about 1000 miles and comes back. Will the tranny fluid fix this problem?The oil still looks new when I change it each time. I use 10w40 Pennzoil and ac delco filters. Thanks

Travis McVay: I'm not saying that Fram filters are the best but the way you're bashing them makes it sound like it was the cause of all that sludge. Sludge is caused by not changing your oil. It has nothing to do with the filter. You also said it was collapsed. I wish you would have pointed out where you think it was collapsed at because it looked perfectly normal to me other than being full of filthy dirty neglected oil...

Russell Booth: So far it's taken 15 months to eliminate the lifter noise in my 5.7 litre LS1 powered car which will clock over to 300,000 kilometres (184,049 miles) within the next week or so.I couldn't work out why some of the lifters have been noisy 3000 kilometres (about 1840 miles) after I'd flushed the engine with diesel then changed both the oil & filter and the lifter were quiet up until that point.I think that a high kilometre engine such as mine and the one in the video ,particularly if it has suffered a bit of neglect can accumulate sludge which can block up the lifters or varnish can build up inside the lifters themselves.I think that while a flush helps,there can also be a lot of baked on sludge deposits which become loosened up over a period of time and the lifters can drag down the sludge deposits and become trapped inside the oil gallery causing nothing but bother as far as lifter noise goes.How did I know it was sludge?,Well, I'd idle my car while facing uphill and one of the lifters on cylinder number 8 would start clacking its head off,2 Fridays ago, I decided to drain to 3000 kilometre oil out and strain it through a nylon stocking,I got a mixture of used ATF and engine oil and strained that too, I put that in the engine and added 1 litre of diesel, idled the engine for 15 minutes ,drained the oil out,fitted a new oil filter and put the other oil back in.The noise seemed to still be there after the engine warmed up after a 10 kilometre drive (6 miles) so what I did last Friday I drained about 1 litre (about 1 quart) of oil out and put that much ATF in,the lifter was still noisy on Saturday (yesterday here in Australia) but I have given the ATF to work its way through the engine as the lifter noise isn't there if I shut the engine off for 30 seconds then give it a few revs (goes away),I drove the car in total of 100 kilometres (60 miles) yesterday and about a mile a couple of hours ago (Sunday night here in Australia) and the engine appears to be quiet.So tomorrow morning is going to be the big test to see whether it was just sludge plugging up the oil porting or if there's still an issue of baked on varnish inside the lifter I still have to persevere with.

jim davidson: You need to drop the oil pan and clean the sucker out. That was amazing what came out of it. The oil pickup screen and pickup tube must be clogged also. Remove the oil pan.

TheBlackShadow270: Jesus Christ that's dirty. I would have poured clean oil in until it ran out clean. Then I would change the oil, run it for a week and change it again

Payton Richardson: you can't blame chevy for your terrible maintenance habits though... the engine wear, sludge and clogged filter is all you. so yeah if it ticks thats a good way to fix it but don't blame chevy for ticking and breaking when you are just a crappy car owner

Jorge felix: I think is not a good idea put synthetic oil on engine whit that cane of sludge , better put regular oil whit Marvel Mystery and run for couple of days and back again change the oil .

knightfive: Im really losing my faith in chevy at this point, went to change my knock sensors, and the one closest to firewall under intake manifold, was so full of just plain dirt and gravel it shocked me. After removing a cup or two of greasy dirt, I then go to take it out and it breaks off, the screw part still in block, and now Im like 2 days into it and still not fixed?? Who f'ing designs these motors, great engineers :(...... no wonder Detroit is out of business, wish Honda would make an affordable heavy duty truck!!

Mopar Nut: If it is in the pan, it didn't make it to the filter. Can't blame the filter for not filtering what doesn't go thru it.

Treavor Wolf: just thought i would throw this out there.. i used quaker state in my rebuilt 350 X engine and a year later i changed it and it looked just like that

Jorge felix: What do you guys expect whit people like this , they never look into the engine bey , and every time make complain about the chevys engines .

Barnekkid: ATF in the engine? Never heard that one before. I'll try it.

Bret W. Caldwell: this is meh new fav. video

scorpinock2: If that sludge is coming out from the pan it means it was picked up by a mesh filter before the actual oil filter and never made it into the engine. If chunks like that got in the lifters at all it would halt oil flow in them, not even just slow it down.

PR O: +AdirondackNY just a quick link to your video update for others interested in this video: Chevy Vortec lifter & valve tap update after using trans fluid thanks for sharing this info, ill be using it on my 94 nissan 300zx na, previous owners must have neglected oil cuase all you can see is carbon/tarnish when you look inside oil filler neck. horrible. cant wait to have a smooth running z again as i wasnt looking forward to ripping into the engine to rebuild the lifters... thanks!

crackermoves: Hello does it matter what kind of Transmission fluid to use??

Albone3000: frams might not be the best but they are adequate. whatever happened to that engine has nothing to do with the filter they used. There is probably water mixing with the oil and it will just gunk up again. 

FireEffective: LoL- it was like watching an accident- I could not look away!!!!!! Napa are great filters. What a bleeding mess- I agree 100% on FRAM- Purolator Pure One- best filter I run nothing but Rotella in all my engines, including bikes.

BurningTirez: This works great... I have an old 350 carbd that I dont really care about rebuilding just yet. Had low oil pressure, valve tap, sludge... 1 qt atf in the oil for 500 miles, I forgot about it but it runs better than ever and is clean inside.

jewllake: LOL looks like it is taking a long crap! I use about 1/2 quart of dexron trans fluid every 15,000 miles and run it for about 20 before an oil change as preventive maintenance. I also use marvel mystery oil. My 5.3's run nice and quiet.

lowell curtis: The 1 quart of ATF and fill with oil trick works , been doing it for years . 

Justin Gibson: lifters will tap in any engine if you dont change the oil.. miles does not have much to do with it i had a 4.3 with 350,000 and ran like a sewing machine but the oil was changed EVERY 3000 miles and all that was put in it since it was new was delo 15w 40.

manny6584: And it still runs. wow

Scott Trigg: I have a 02 maxima that has a slight lifter tap I'm going to try the trans fluid and see what happens

brianallen0826: How long do u run motor with atf? Do u use a quart of atf instead of oil, or just add the quart of atf.

lowell curtis: I got one like that, changed the oil and BOOM ! hahaha scattered ....olds 350 rocket 

Aaron pfannstiel: You can't blame the filter it looked like the oil had never been changed. I only use fram oil filters and have never had a problem with them on my 05 chevy 5.3 that has 153,000 miles on it and countless idle hours.

Justin P.: Not the trucks fault at all, clearly, the oil hasn't been changed in along time...

jewllake: YES! Fram blows. I use motorcraft, A/C Delco( non eco filters) wix, Baldwin or Napa .

ScaleCarModels: Great vid just got a 06 sierra 5.3l with 47k miles and starting to hear a slight ticking/tapping noise. I have learned a lot of these engines in last few days regarding the vortec series of engines. Will keep this method in mind just had it changed few days ago running synthetic now. Thx for posting gonna keep eye on the noise.

Lance Taylor: Excellent video, thanks for sharing. 

jojojeep1: that tic you here is the lule injection , that motor sound's good'

Justin Gibson: thanks for sharing this video this is good to know. I just cant believe someone could neglect a engine that bad i mean it cost 30 buck max every 3 or so months to get oil changed. Hurts my soul to see oil that bad...

The8TrackChap: Wow. The oil pan is pooping like a dog.

vza423: What was the next oil change like, how often would you suggest this procedure?

Warren Peace: This video reminds me of a bad Taco Bell experience I had. OOOO IT BURNS!!!!

sixfittyonembitties: I've notices this sound in my 99 Camaro z28. Has anyone done this with an ls1 like mine? I assume it should work. Also, what oil and oil filter would be the best for an ls1? I've got about 110,000 miles now.

damonlee22: I don't think the fram filter had anything to do with the problem here.. I have an 2005 Silverado 5.3 I've used fram oil filters it's entire life, and it now has 293,000 miles and still running strong.

Jesse Woolard: I put trans fluid in my truck 1000 miles before each oil change and my motors have over 300000 on both.

Jeff Burge: If it saves me money as opposed to buying a rebuilt one, then I'm for it! I have a 02 Avalanche 

Panty Snatcher: This is what happen when you give it a Hysterectomy, you get clots !!! very good video and change you oil ....

jim davidson: Rislone in the oil is all you need. Been around for a hundred years. Ask grandpa and your dad about it. They'll educate you quickly on it.

Russell Jones: I wouldn't blame the FRAM oil filter. Someone must have driven with that oil for 20,000.

roodmood1: adironackNY, whats your thoughts on Seafoam vs trans fluid?

whitenas: i dont understand why your knocking chevrolet. its amazing it runs as well as it does with that crap comming out of the pan. if anything its true testament to how well gm enginiers and builds its engines. you said it yourself ...if you dont change oil regularly this will happen....it would happen to any car with that lack of maintinence.......a chevy fan.

videocoop: I'd be interested to see the oil change/drained oil AFTER the tranny fluid treatment. I mean, if the original oil was neglected and the Fram filter was crap, then I'd sort of expect to see clumps in the oil when drained. But, I'd be very curious to see what sort of gunk the tranny fluid breaks loose. Hope you haven't done another oil change on this truck yet - if not, please video the next oil change and let us see it!

Ray Josephs: The filter has nothing to do with the crud...problem was the oil wasn't change regularly.

vipervin1: I agree with Fram being a low quality filter. I have cut all of them apart and indeed Fram is a inferior filter. However the sludge condition is not related to the filter. No single filter would provide filtration to oil in that condition. BTW I would definitely check the oil pump screen in that engine. 

rja777: Nifty trick thanks. I would have dropped the pan to.
