Head gasket question
« on: January 25, 2018, 09:16:44 AM »
If I pull the heads for a cleanup and .030 gasket change, should I replace the bottom cylinder o-rings as well?

Thanks

I never have when performing such a cleanup.  I've not had problems with leaking.  Also, if you pull the cylinders off the pistons, then having your rings seal back up without issues is nearly impossible.  This would cause you to have the cylinders de-glazed and new rings.

I would not mess with the o-rings at the bottom of the cylinders.

You're welcome, and also try not to juggle around those cylinders too much if possible.  I know it's hard to break the seal on the stock head gaskets without jiggling the cylinders, but try to get a friend hold them down firm while you're doing it.  Use some plastic plumbing pieces under head bolts to hold the cylinders down (two diagonal each cylinder) if you'll be turning over the headless engine.

Bottom line:  You don't have to touch the base o-rings, but also don't go poking the bear in the nose.

I always replace base the o-rings, my thought goes back to the EVO with paper base gaskets, they would often leak with low mileage, I would remove the cyls, replace the gaskets and reassemble, never an issue with the rings sealing back up. I carried over my process to the Twin Cam without issue, a plus is you can inspect the rings and replace if necessary.

Les, with your insight, I may change my ways.  :beer:

You could always leave the pistons in the cylinders and pull them together. I would replace the o-rings.

It depends on how old the o-rings are, I have pulled heads several times left the old o-rings in with no problems.
On a stock build if you pull the cyclinder you are going to find the rings at the max tolerance gap+ so expect new rings.

Depends on years and or run time... if you get a upper engine gasket kit you can add those o rings for dollars on the penny. As a tech I would ALLWAYS recommend to do it all, an extra 20 min for me can save you hundreds. Now if you just doing in you garage and you donít have the oil ring compression tool getting the pistons back on the cylinders can be ... challenging ... and make sure you never line up the holes on the oil rings.. over all Iíd do it.. but Iíve done quite a few. But it not REQUIRED

 I just did heads and thinner mls head gaskets bike has 10,000 miles i only replaced the o-ring around the dowels not the actual base orings no issue but i do think you could pull cyl an pistons an reassemble without honing etc ! Jus try to not turn the rings to a diffrent pos on the pistons .

I've done it both ways - never a problem on TC with o-ring leakage but I'm careful not to disturb the cylinder seal to the case.

Like Billy said, EVO's are another story

I'm kind of a flat rate guy so I'm not interested in pulling the cylinders unless parts are being changed...sounds too much like extra work that the customer may not want to pay for and that I'm not interested in doing for free. It's all in how you sell the job I guess.

I left them alone on my personal bike.

It's a bit of a gamble I'll admit, but a pretty safe one.

It's like this, if you don't replace the base o-ring, and there is not a leak later, it's all good. If it does leak, you do it again.

It's really only about time. There's a good chance it won't leak, but guys that have said they do it, some are shop owners, and they want a good reputation and a happy customer. I look at it like this, with the heads off, you're 30 minutes or less replacing both o-rings, and the oil return o-rings, so why not?

1/2 hour now, 8 hours later? :banghead:

Low miles, fairly current year I probably would chance it. Ten year old bike, or a bunch of miles I would pull the cylinders. I would probably hone and drop in a set of rings too as long as the cylinders measured good, on a higher mile engine.
I am an adult?? When did that happen, and how do I make it stop?!

Here you go. This is what happened to me. Shortly after this discussion it happened to another well known member here. This may have corrected itself over time but finding it while tuning we ended up trouble shooting it and this is what we found. There is the evidence they rotate. I know and have a clear recollection where those rings were initially indexed. The ones that stalled in the lined up position could be related to the shape of the cylinder (that wasn't perfect but was well within spec). The other cylinder was OK but the rings were no longer where they started out.

I seriously doubt his bike is ten year old and high mileage. He's changing head gaskets to get more compression. And more HD cylinders get fubarred by a ball hone than if left alone. And if you use a conventional hone, you better have torque plates.

Ohio, my example was just intended to support the statements made about ring rotation as a real life example and not as a recommendation to ball hone or otherwise. We did the ball hone because we had rings, torque plates and the cylinder dimensions before it was run. It was a light touch to help a new set of rings and nothing more.

That's fine Ohio.  :up: My response was mostly for the benefit of the OP. It was to show real evidence of ring rotation and I was putting the post together before your contribution popped up. The circumstance of having a blueprint of the barrels, the parts and equipment availability, and the fact the engine was only a few hours old were the deciding factors in my case. I otherwise would have no problem reassembling with the present ring set and have done it in the past with several types of engines. .

Thank you. I have the o-rings. I got them with the top end gasket kit. And I don't have a problem replacing them, I just didn't know if it was necessary because I couldn't find any information on the subject. Now there's plenty.  :up:

As busy as I stay, I wouldn't consider NOT changing the gaskets, seals, etc. under the cylinders. One leak because you didn't do that not only will cost you time, but most of your top end gaskets as well.
FYI, rings rotate. It's the cross hatch that controls that.
Usually the bottom of the second ring will tell you what condition the rings are in. Removing and installing the cylinders will NOT affect the seal that you had, unless you screw it up by poor installation. Don't hone the cylinders if you remove them and are going back with the original pistons. You're sure to add clearance.

 :up:   I agree with you John. Even on my own stuff, I really don't have time, or want to do things twice. If anything, I'm overly complete doing things.

When you say the bottom of the 2nd ring, what are you looking for? The lower edge of that ring being dull or rounded?

I like to see a fine shiny line, not more than .020" - '030" at the very bottom of the 2nd ring. If the ring is shiny across the whole face, then it's time to replace the whole set, after checking the piston to bore size. 9 out 10 times, you'll go to the next oversize piston and bore. :cry:

Ok, that's great info John. I've seen what you mention when taking a motor down, where only the lower area of the ring face is shinny.

Seating is not a great term for describing ring break in. The rings wear to the cylinder surface (marginally) and the softer ring land machined surface likewise forms to the harder ring top and bottom to seal better. Once these surfaces are mated and sealing they are good until excessively worn and the ring gap widening weakens the contact with the cylinder walls.

Others have more experience, but I have only one first hand experience with someone I know who pulled the jugs off and put them back without de-glazing and new rings.  He never got the rings to seal properly again and ended up taking it apart, honing, and new rings to get his engine back.  So, since this is the only situation like this I've seen, I don't pull the jugs unless I'm prepared to refresh the ring/cylinder interface.

Correct, you will have a tough time making the base gaskets seal again. My point, why gamble.
Just to be clear, I don't want to beat a dead horse, but you WILL NOT affect the piston ring to cylinder sealing by removing the cylinder, and re=installing. For that matter, you can remove the rings from the piston, keep them in the order of removal, re-install, and you won't have a problem with that either. :wink:

No gamble here. I replace everything between the bottom of the cylinder to the top of the case, if I have the heads off no matter which engine I work on. Cheap insurance.

For that matter, you can remove the rings from the piston, keep them in the order of removal, re-install, and you won't have a problem with that either. :wink:

John, does that go for Twin cams with the o-ring in rebate?
No gamble here. I replace everything between the bottom of the cylinder to the top of the case, if I have the heads off no matter which engine I work on. Cheap insurance.

Worked beautifully. Thanks :up:

How many miles are on the motor?

If its 40K ish or more, then not putting rings in while that far in doesn't make any sense.

If you decide to not replace the rings, and just scrape the carbon, then get a set of service nuts.  That way you can keep the jugs bolted in place as you scrap on the pistons.  They are like little head nuts with an extended sleeve to reach the threads down in the jug holes.  You can do it with the head nuts and spacers, but they tend to get in the way, standing up off the jug several inches.

Sounds very nice in the garage, but the weather isn't good enough to get it out yet. The whole job went very well though. Rather easy actually. I removed the wrist pin to make the install easier, but I did pull the piston out to inspect everything. As far as I'm concerned, it all looked good.

35,000 miles on the motor..
