What ensures, that the rings don't move the gaps during time?

Once you place the ring in the desired groove , you roll the rest of the ring on . The distortion on those rings displayed disturbed me .

that hurts watching how you put the oil rings on lol. But your still the man

Super helpful, thank you

Good video!

very helpful, thank you!

Vefy informative good to know. Currently troubleshooting a po302 on my Subaru sti

thanks lake

‏‪0:20‬‏ Hello, what is the best oil rings, 3 pieces or 2 pieces?

Thanks

Oh and I remember i have seen once a motorcycle piston with tiny anti rotation pins, so that they stay in place at very high rpms.

Unless pinned rings rotate. You can't stop them from doing so.

The instructions on the ring box say do not put any ring gap's on the thrust side of the piston

Nice video, very instructive! But that's in the best world possible, actually piston rings rotates slightly due to engin inherent vibration.

I have a question, so my pistons have a .200 oil Grove and I got some rings that supposedly match the oil Grove, when it's time to compress them into the cylinders they won't budge, is it the type of compressor I'm using? I've tried the fixed angle and the rachet type and the piston gets stuck as it's about to enter the bore. Does that mean I needa rebore the cylinders?

They’re going to eventually line up, they’ll rotate at around 6 revolutions per minute and at some point they’re going to be in line. Just have to have a way of venting the crankcase pressure that is created.

Trying to understand. So, you are suggesting we place the top & 2nd ring gaps in line with the piston pin? Thanks.

Why did he put the bottom scraper on before the expander ? The scrapers are meant to sit on top of the little ridges on the top and bottom of the expander right ?

Well that solved my question, do the rings move round when the motor is running.? And the man said that they do indeed.! I can stop worrying now.!

Shouldn't the expander ring go on before the two oil scraper rings? The scraper rings push against the expander ring as there is a lip on the inside of the expander ring on the bottom and top which is there for the top/bottom oil rings to keep the expander in place. Your video shows the first oil ring going in before the expander which I believe is incorrect. However I don't think your expander has this lip like I have on my BMW expander so it might be OK for your application

So I guess the octane value must take an incredible hit with blown and redurning through the EGR. It's a wonder that with these fuel mixtures, the vehicles even run. How can you say that the emissions are better?

Can you explain "thrust side"? Thanks, TJ

Why would there be blow by when they are aligned and when they are not. Pressure goes where it can go.

Hi

How can I know the first from the second ring ?

I turn each ring 180 from one another I was taught not to line up a ring gap to a piston pin I know it don’t matter but 180 from one another is better then him doing oil rings 180 and the second ring only 90* from the oil ring gap why would u not go 180 from each gap ?????????

How, if the top oil rail is placed on the thrust side of the piston, is the second ring 90 degrees from the top oil rail gap on the exhaust side when it lines up with the piston pin which is neither exhaust side nor intake side???? Lake needs a script and a diagram of what he means , a much better teaching aid. The thrust side changes from bank to bank in relation to the piston and the intake and exhaust side of the piston. Again, Lake used the term intake and exhaust to describe all pistons. Another thing, why would the intake side be cooler when the intake charge coming through the ports splashes against the exhaust side of the combustion chamber then swirls in the direction of the exhaust valve as the piston goes down? I would like a physical demonstration using a piston and a bare block explaining the major thrust side of a cylinder wall and a piston before explaining gap position. Just holding a piston in hand for a V8 is not a good demo. It is assuming everyone viewing knows what piston thrust is and which side of a cylinder wall on each bank is. What I just witnessed was confusing. Lake spoke and moved quickly because he understands this perfectly, a common mistake for someone in the know. Keep it simple, just do not line up the end gaps. It is unlikely that after a bunch of miles or possibly by the end of the break in, where you placed the end gaps will have changes completely.

I just set them 180 from each other

People always sh*t the bead of rings, and placement of the gaps… They spin all around durning operation. Where you put them initially, is not where they will stay for ever… Set the first 2 up 180* from the other as you go up, like he said, every 90*…

Octain value must be dem

Its really hot today and my ring got stuck i cant get it off should i put my finger in the freezer?

so wrong mate you never put ring gap over guedon pin

That foo dont kno hot to install rings

terrible ring installation method. You are scrapped the all piston rings dude. Did hear before about the bend over the rings and you are sure before did that?

DON'T LISTEN TO THIS VIDEO. Consult with factory service manual for your application or contract the piston manufacturer.
