How To FIX Chevy’s LS Piston Mistake - Oil Consumption Fix In Minutes [DRILLING FOR OIL]

While the Chevy LS Engine is one of the most popular powerplants for hotrods today, they all suffer from this same issue. On the surface, the problem signs show in the form of oil consumption, but it's not the typical valve seals that are the only culprit. You may need to dig a little deeper.
The top two rings of the LS pistons do the hard work of sealing the combustion chamber and helping to create compression. This is how we get the big boom out of the tailpipes. However, it's the oil ring/s that do the real dirty work. Pressurized oil lubricates the bearings, wrist pins, and even the cylinders, but this oil shouldn't make it to the combustion chamber. It's the oil rings job to scavenge this oil from the cylinder walls and return it back to the crankcase and oil pan. This procedure not only squeegees the oil straight down the cylinder walls, but it also collects the oil in the ring-lands of the oil ring/s. The scavenged oil in the ring-lands should, emphasis on should, drain back into the oil pan by way of reliefs.
The old small-block Chevys, back when we used to size engines in Cubic-Inches (283, 327, 350, 400, etc.), they used huge "windows" or slits manufactured into the piston oil-ring-lands. These LS pistons have 4 small notches manufactured into the bottom of the ring lands. Over time, these small notches clog up and they can't scavenge the oil like they should. Once this happens, then oil starts getting into the combustion chamber, thus oil consumption goes up and smoke makes it out the tailpipes. Fear not, there is an easy fix. Just drill some holes. A 7/64" drill bit will fit nicely in the width of the oil ring area.

The original Saturn engines used the same drain back feature and it wouldn't take long for the engine to start burning oil. Back in 08 I rebuilt the engine on my Saturn and did this mod, I think I drilled 6 holes in each piston. Long story short, the Saturn was able to go another 200K miles without burning a drop of oil. As a mater of fact the engine was still running great when I scraped the car.

To help speed up the layout of the new holes, use a seamstress tape. They can be found in the sewing section of Walmart, or wherever. You now now that you need 1 3/8" from the factory slot, to the first hole, to the next hole. Start at a factory slot, make a Sharpie mark, and you are done.

I would add a piece of wood screwed to the board that the face of the piston would butt up against as a stop. Once you get the first one set, getting the others would be easier and more stable during drilling.

[@SloGN]

What’s really interesting is that the LC2 Turbo Regal/grand National engines has this same type of oil control /drain where it forces the oil down to the wrist pin. I have taken a bunch of those part and never had a issue with the oil rings being coaked up with carbon. And or burning oil.

[@mariopic]

the holes need to be drilled below the upper oil scraper ring to avoid oil going under the ring

[@prevost8686]

We were doing this procedure on some Toyota 4cyl. Engines back in the late 90s. Low and behold Toyota eventually offered redesigned pistons later to help correct the issue. High quality synthetic oil run at reasonable intervals will help prevent buildup in the oil rings that make them stick.

[@chubanderson1765]

My guess is many burn oil because when installing the oil ring, many don't check to see if the expanding spacer between the two thin steel rails has not jumped from being butted up against each end of it. You just look at them and they slip past each other. I ordered eight pistons and the rings were already installed, and in all eight the spacer was not in correctly. The spacer is what exerts pressure on the rails to push against the cylinder wall.

[@Shoptoolreviews]

Correct, that's why they're called the expander ring. However, we're talking about an issue that was done at the factory. I have a hard time believing that all of the factory expander rings were installed wrong. Thanks for watching.

[@sethnelson8698]

I have a 4.8 lr4 that I'm gonna be swapping into my 70 lemans. The original plan was to slap a btr stage 2 truck cam in it and go. But now that I've done a little bit of research on the oil cunsumption issues with these motors and how to fix the issues, it's has made me consider if I should at least take the pistons out replace the rings while I'm at it and fill those little holes that u were drilling in this video. I already have the motor down to a shortblock anyways and it wouldn't take very long to do, I'm just curious if it's worth it. The truck it came out of had 250k miles on it but the motor was super clean when u took it apart, no valve train issues, no leaking valves or seals, the pushrods were undamaged, but I think I'm gonna get new lifter while I'm at it since its apart anyways, and I was also curious on running a ls9 cam instead of the btr stage 2 v2 truck cam that I have for it. Just wanting anyone's thoughts and opinions on this.

[@sethnelson8698]

Damn the was alot of words

[@Shoptoolreviews]

Since you're so close and the expense is pretty low, I'd recommend to pull it apart, fix the pistons, run a dingleberry hone through the cylinders, and install some new rings. Also, gap the rings appropriately, especially if you're thinking of a turbo. Thanks for watching.

[@sharonmiller9151]

So, is this THE cure, no but it is an easy thing to do that can only help. If it does nothing more than keep the rings free it's a great idea. An oil catch can in the PCV tube is also a great addition. I would also like to add that almost NOBODY changes pistons on an LS. I have NEVER seen one with a ridge at the top, or pistons that were worn out of specs, why spend at least $300 for pistons unless you really hate that piston slap. My buddies truck was down 80 hp at 275k, new rings and a bigger (stage2)cam, boom 180 hp gain. These blocks, hypereutectic (hard surface) pistons, and better oil keep these from wearing like any old engine from the 50-60"s As a GM World Class tech and slobbering car nut, I have pulled lots of these apart. Most all of them have stuck rings. I have also seen it on many other engines, besides GM (for all you haters). Seems like every manufacturer has oil consumption problems: 4 cylinder Ecotec Mini Cooper, 4 cylinder Chrysler, Nissan, etc. Later model LT engine have holes behind the oil rings, and a different PCV system, very few oil consumption problems. Now in my experience with these engines it is rarely just one thing that causes this problem. Cheap oil (Dexos is great, cleans out sludge and is available at Wal-Mart cheap), extended oil changes, and to me the biggest problem, putting around like a 90 year old and the engine never sees 3,000 rpm. Worst ones I have seen is the 6.0L, I had to do lifters on two in a row. One had so much carbon build up it filled the quench area and you could tell where the combustion chamber started. The next one was clean as a could be, very little build anywhere. I made an effort to talk to the customers and the first one used oil and they said they drive pretty slow. The second customer said they drive like their hair is on fire. The MPG showed it too.

[@ferberb9662]

Wow 😮this is cool, I have a question I have a 2017 Kia soul and is starting to burn oil almost a 1quart every 2000 miles Can this be done in the pistons on that engine if I rebuild it, the car is awesome and it has good mpg everyone your comments will be appreciated.

[@ricardo340]

If I have the pistons out odds are I’m not going to reuse them. Aftermarket.

You can buy aftermarket, but most of these LS pistons are perfectly fine for reusing. They're also very safe to build 600+ horsepower. That's pretty cheap performance. Thanks for watching.

[@pingpong9656]

Does that not require the crankshaft to be re-balanced?

[@juanrocha6548]

Same thing on 6.2L pistons??

[@pauljanssen2624]

The reason why they did that design is to keep the oil on the skirt of a piston you can see the drain back holes where the pin is yes in the LS engine has a poor PVC valve system it's all about how much you change the oil and you should use a good durablend or all synthetic

[@Shoptoolreviews]

You are correct, for the most part...or at least I agree with you for the most part. However, they still should have allowed for more drain back in the pistons. It's a very common issue, in both dirty and well-maintained engines. Thanks for watching.

[@KatiTheButcher]

I have a missfire in cyl 6 in my 99k 2011 4.3 silverado. Rough idle, not burning oil and no knock. Went through a plethora of tests and intake gone through. My question is, is the 4.3 truly an LS with 2 less cylinders? Im about to say f it and rebuild the damn thing.

[@davidtaylor1384]

Probably said on down, but screw a piece across the v joint and jut push the piston top against it to stop wobble.

[@chuckpatrick9926]

Your positive that it can't hurt integrity or unbalance it a little. Just wondering, there known for chippy the top edge off the first ring already. There swallow pistons and a awesome idea

Weight will be negligible. I'm thinking the structural integrity would be weakened though..... I'm not going to try this on my turbo 5.3, and find out.

[@johnbaidas]

Performance pistons normally have drain holes and drain to the wrist pin

[@Shoptoolreviews]

Under boost, they are known to pull the top off the piston and the first ring, but you're doing the drilling at the oil ring. You're not removing enough material for the pistons/rotating-assembly to be out of balance. If you're concerned then just weigh each piston/rod and match them before assembly. Thanks for watching.

[@basshnter1997]

I wonder if this issue is what has caused my 2001 4.8 to burn oil since new?

[@Shoptoolreviews]

I would venture to say that the culprit is probably the valve covers and PCV system. You can find videos on fixing this issue in the valve covers. Thanks for watching.

[@ze_german2921]

just restored an ls4 gxp been driving daily in Ontario. As I was doing mini restoration and paint touch up and paint correction I soaked all the combustion chambers in. Kleens combustion cleaner for a few days to clean ring lands and free rings as it was a stock motor with dod then changed the oil with 5-40 synthetic and hi quality filter the car has over 100000 miles and runs and sound like new the 5.3 uses no oil . Also for gm front wheel drive transmissions I used transmax synthetic and a biggest transmission oil cooler . Purchased the car cheap because it had a destroyed transmission. One I replaced it with a rebuild I checked the temp and on a 75f day it would spike to 218f way to hot and it actually started to darken the new Oem dex so I flushed it and added the rv cooler in series with the Oem rad cooler and added the trans max synthetic to replace the Oem fluid the car runs 175f after freeway 75 mph driving of 100 miles . So in my opinion the cooling and hi quality synthetic fluid will help keep the transmission alive with a yearly service of removing 7 quarts pumped out transmission dip stick tube

Perfect. You're right! If I were to make a video doing this, 75% of the viewers would tell me how that's not precise and everything will be out of balance, etc. Even though, I know it would be fine. Thanks for watching.

@@Shoptoolreviews I've built couple hundred engines in my time. Zero chance I would have wasted my time in this. Just replace the pistons with something better.. If can't afford it then buy plenty of oil and keep it changed.

It's sad that Chevy overcharges it's customers and does this.

[@Shoptoolreviews]

Not sure I can agree with that one. Chevy is still the biggest bang for your buck in the horsepower game. Thanks for watching.

[@UltraGamma25]

@@Shoptoolreviews I used to sell Chevy's at a dealership. Only lasted for 3 months. They overcharge for everything. 50k for a sedan whereas a new Volkswagen Sedan is only 20k with all of the features. I mean sure, powerwise it's good but one can not deny that they've lost their touch and are cutting too many corners. Tarnishing the brand. Chevy used to be #1 in my books.

[@cerace9120]

Please don't take apart your engine just to compromise and unbalance your pistons.

[@Shoptoolreviews]

By no means are we recommending to dismantle a running LS for this alone. It's meant to be done when you're rebuilding anyway. It makes a difference. Thanks for watching.

[@nickcarter845]

Please don't come to someone else's video and make remarks about things you don't know about. Literally not compromising the piston and remind me how much a couple of aluminum shavings weigh again.

[@tahcogunworks]

You're clueless. 4 holes do nothing for weight and yes I owned a machine shop for 20 years.

[@tahcogunworks]

@@RwP223 wrong. Absolutely wrong.

[@LuigiSpada]

This is why I am happy electric cars are becoming more common. The internal combustion engine has been around for over a century. Billions of pistons have been made. The engineers are STILL screwing it up. If they haven't figured it out by now, they never will.

[@bigredracer7848]

You definitely over complicated a simple matter

[@zipcitymotorcars]

oh ya!....theres not an easy way to fix this....lol

[@psk5746]

The LS isn't perfect as many want us to believe after all

[@alcunningham5103]

But... Now you must rebalance the piston if you are running high rpm's

[@stephanouellet3673]

4 small holes like this in aluminium doesn t have weight difference to need rebalancing the rotating

[@zedee2000]

I agree GIF it's under a half a gram in weight it shouldn"t make a difference. But if you're going to balance it do it after all the work is done then balance.

[@thechiefenginer]

Paying 80K for a truck, but immediately have to make customizations so the engine doesn't blow up? What am I missing? I just has a 6.2L blow up on me. Upon research, i am seeing that GM engines have a lot of issues. I am beyond disappointed. I suppose GM wont admit nor fix, as that will admit fault. Good to know. My business will never be with GM again.

[@kenbritt8616]

Because its GM and all they know is stupid junk

[@Shoptoolreviews]

I don't think that's exactly true. The LS is still the go-to platform for building cheap power. What other motor can you buy for $400 (used) and the stock rotating assembly hold together for 700hp+? It's a well-proven platform, but not without a few cautions. Thanks for watching.

Wait a Minute . I think you’re doing more damage . The ring is actually called an “oil control ring “ . It also supplies oil to the cylinder walls and aids in lubricating the skirt . It’s. Not supposed to drain all of it . Engineers designed it without holes for a reason . Just a. Heads up . It’s not scavenging oil to take back to the pan , it’s scavenging to later be deposited back on to the cylinder wall . You don’t want to get rid of it .

Yea Ls stands for Last of the Seconds. . Cheap horsepower 460 with a 6-70 even the new godzilla motor can't touch it. For a good point A to B performance motors just run the old 350 or Ford 302 why complicate things. .
