Re: Ok...decided to pull the motor to junk the gapless rings
Has anybody tried using the Total Seal compression rings and stock LS1 oil rings?

Re: Ok...decided to pull the motor to junk the gapless rings
I had the same troubles with the gapless 2nd ring design.
They pull oil through the guides and suffer from lousy ring oil control.
I used standard tension oil rings with them also.
Would never use them again.

I can not explain why, but they seriously pulled oil through the valve guides.
I initially noticed the problem on the plugs about 400 miles after I used the rings..
A couple plugs began to foul with oil and it smoked on startup.
Leakdown showed almost 0% on the problem cyls.
So then I pulled the intake and saw a good teaspoon of perfectly clean oil sitting on the closed intake valves after running the motor and letting it idle for a bit.
Could Not belive my eyes when I saw that!I thought I had a crack in a intake port or something.I tried new seals with NO help.
Well after a lot of other testing including a port pressure test,I finally had to pull the motor again and even began to think I cracked a piston or something as it is a supercharged motor.
I was thinking of all sorts of scenarios that would allow this much oil to get on top of a valve,lol.
Tear down showed each and every piston with tell tale burnt oil spills on the piston tops.You could so plainly see how EVERY cylinder was doing this.
This proved oil was dripping down from the guides to the top of the piston.Some worse than others.
Now I can't explain why as I ONLY had about 1-2" more vacuum with the gapless rings.
The pistons came out relatively oil free between the lands/rings indicating it was not oil ring control but rather the oil made it in from the guides mainly.
But something odd was occuring that it had such a strong vacuum pull in the intakes.
Performance was great. But oil control was horrible.
Cylinder wear on the thrust sides also showed a lot of wear.
I can't say the motor did not run good with them.It did.Very good actually. Just very odd oil control problems I have NEVER encountered before.
They state very clearly in the ring instructions that you better have good tight valve guides and good seals.
Mine measured in a factory specs.
Not good enough I guess.

Re: Ok...decided to pull the motor to junk the gapless rings
I have used these rings on a turbo Supra and it smoked like a bug sprayer. I removed them and installed regular Toyota rings and all was fine. I talked to a guy that raced turbo bikes and he said they wouldn't work on them either. They sound like a good idea, but they just don't work. I would like to know why.

But don't Total Seal tell you to put restrictions in the vacuum lines because of the extra vacuum produced by these rings? Has anybody tried this?

SO what your saying is they suck more? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Brian, what about selling your dynas and gettign some jethots? Lemme know if you want to know some prices <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Or how bout putting some diamond or rosspistons in there while you got it apart <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> You know you aint gonna stay NA for ever <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Ok...decided to pull the motor to junk the gapless rings
I'm having the same exact problems as SJH described... a teaspoon of oil on top of each valve. Compression test is awesome (haven't leaked the motor but it is most likely ok) and it runs AWESOME...
just the oil smoke SUCKS!!!

Re: Ok...decided to pull the motor to junk the gapless rings
Sounds like i got that same problem as you. I smoke bad, burining alot of oil, i loose about 1 quart every 700 miles. I dont have total seal rings though, but 1/2, 1/2,3.
Reckless and i pulled the intake to install a ls6 intake on and i had oil all over my cylinder intake ports.
Tell us what you find.
ill probably do a compression check this week or next. Havnt been driving it thanks to the snow. but going to install my air pump to evacuate the crank case pressure, hoping to have some luck with that.

Re: Ok...decided to pull the motor to junk the gapless rings
If you run gapless 1 and 2 rings then you can occasionally get compressed gasses trapped between the rings, which causes ring flutter, and can lead to poor oil control. I would only run a gapless top ring if I were going to run gapless at all (but I wouldn't - I would just stick with a je/hastings ringset).
