Can i reuse a cometic head gasket

There are numerous misconceptions in the high-performance world on what you can or can not do with countless parts. Amongst the a great deal much more typical ones out there is that reusing MLS head gaskets is faultlessly fantastic, nevertheless also if you pay attention to something is true does not suggest it is. We spoke to Mickey Hale from Cometic Gasket to see if you can, in fact, reuse an MLS head gasket.

Head gaskets are in fact what aids to preserve all the fire inside the engine where it needs to be throughout treatment. If a head gasket is threatened, all type of adverse factors will definitely take place rapidly that will definitely hurt an engine as well as likewise the owner’s budget plan. Preserving the sincerity of the gaskets intact will definitely preserve an engine running right as well as likewise making great deals of power, so taking advantage of a fresh gasket is actually essential.

According to Hale, the mistaken belief of having the capability to reuse a MLS head gasket has in fact been around for time, nevertheless it’s a little misdirected.

” While we see it on online discussion forums as well as likewise message boards regularly worrying reusing MLS head gaskets as well as likewise the success of the method, its falling short cost is a great deal higher after reuse. The variable behind this is: once the gasket is heat cycled, the embossments will definitely not get better to where they were originally. In a mock-up circumstance, it is faultlessly ideal to establish, take a look at clearances as well as likewise reuse the gasket. As quickly as heat is recommended the gaskets, the ‘spring’ is gone as well as likewise thinking about that the embossment is the protecting place, there is a far better chance of a coolant or compression leak.”

Presently, if you stay in a general bind at the track as well as likewise need to reuse a gasket for simply a handful of runs it’s not excellent, nevertheless it can be done. If you’re trying to reuse a head gasket as a lasting solution, that’s opening up an unsafe door to a number of problems. The risks consisted of with not taking advantage of a fresh MLS head gasket much surpass the benefits enough to make it a superb principle to preserve an added collection accessible whatsoever times.

” Besides the a/c leakage or a compression loss, oil retention could become part of play. Most of times with any kind of sort of MLS-type gasket, any kind of sort of leak is contributed to 3 factors not continuing to be in play: right torque configurations, right area finish, as well as likewise the gaskets not being completely pushed. An MLS gasket, when all 3 of these variables appertain, will definitely not leak as well as likewise hold a big quantity of cyndrical tube anxiety. I would definitely also declare that consisting of an improvement sealer, while it could seem like a superb principle, in fact isn’t. The gasket presently has a sealer on it, consisting of another layer of copper layer or equivalent keeps the gasket embossments from pushing completely to do what it was recommended to do; consider it as hydraulicing the gasket in theory,” Hale reviews.

If you desire to find even more worrying MLS head gaskets as well as likewise numerous other engine protecting components consider the Cometic Gasket website right listed below.

I have in fact reused mine 4 times presently. Like the others, I got rid of the rivits as well as likewise cleaned them in the Safety and security Kleen parts cleaning maker, dried them as well as likewise sprayed the outter layers with copper spray. I took an electric scriber as well as likewise considerable each thing (in a non previously owned location), so they regularly return in the precise very same location.

I acknowledge I’ll be thought about the ridiculous old individual.

Yet I take my very own apart. Clean them well, afterwards spray 3M #99 adhesive on each of the layers while building them. Afterwards I screw the straight as well as likewise there’s never ever before been any kind of sort of issues whatsoever. No seeping. No leaking. Not an issue.

BTW – copper layer never ever before profited me.

Ive had 2 numerous individuals at Cometic notify me they shouldnt be reused. Which is specifically what I would definitely expect them to case.

Yet, Ive took a look at where alot of individuals do reuse them.

Quote:
Visual states certainly nevertheless what they do not case is that the stick layer from the production center is gone the extremely very first time you tear it down!

I acknowledge I will definitely require to look, nevertheless I have in fact done 2 last setups up as well as likewise am yet to end it.
I most likely to the variable of twin tracking my twin tracking, nevertheless I have in fact too much entailed this deal to take any kind of sort of sort of found an oversight, as well as likewise have in fact required to solve an oiling worry I situated when priming that needed amongst those teardowns.
They have in fact been torqued, nevertheless not seen heat.
Is this a variable?
I will definitely notify you what I find, nevertheless I am sort of wondering about. if they have not been run, does that issue?

I dealt with a similar experience on a fresh unfired engine I called Cometic to buy another collection as well as likewise they notified me I could reuse them as long as they actually did not experience a heat cycle. I notified him simply just how much $$$ stayed in this engine favor to play it safe than sorry as well as likewise I would certainly incline paying the added coin for another collection. Again he mentioned it would definitely be fantastic to use them so I did.

  • Can you reuse head gaskets?

    I acknowledge any kind of sort of head gasket with paper should not be reused nevertheless can the all steel ones be? I have a all steel Cometic head gasket with around 2 personnels. on it as well as likewise desire to do a head swap. I can not find anywhere that markets merely the head gaskets simply collections. I do not desire to buy a whole topend collection if I do not require to.

    search a honda distributors oem parts finder. you can get merely the head gasket. 90-91 cr head gasket 12254- k23-000 is the slim one. i think the atc & 86-89 cr is 12254- ks7-881 the trx was the thick one. made use of to be a 12254- ha2-771, nevertheless i think it was updated. somebody could have much much better information for you.

    Yet my birthed is.80 over or 2mm bigger so can you get them with Honda for overbores?

    I re-use them each of the minute. That is if they do not tear or look adverse. It takes about 30 mins to change a head gasket or a lot less.

    Like mentioned over, use the cr gasket if you desire to bump up your compresssion as well as likewise consist of a little hp. Yet you could need to use a higher octane gas if you do.

    You do not need to get a 2mm over gasket. The supply one will definitely fit.

    My difficulty is I have 225-230 psi as well as likewise in some way I am not seeming nevertheless still desire to put the supply straight also if I feel I am losing on some power?

    mines worn out 0.080 over too. i have in fact never ever before had a supply birthed, nevertheless i still use those gaskets. i have in fact been notified you cant use’em develop the steel overlapping in the burning chamber will definitely replicate a luster plug as well as likewise develop pre-ignition. they profit me effortlessly yet. i think i seen overbore gaskets seperate formerly on cometic web site. potentially try that if you do not wan na use oem.

    3 Bond #1211 sealant & theres no end to just how much time you can re-use that steel head gasket, that is, as long as you do not flex or warp it real adverse.

    Hi Y’ all, as I was building the leading end. head as well as likewise base gaskets. I disregarded a number of factors. I have MLS head gaskets as well as likewise rubber split steel base gaskets both from Cometic. I was wondering about if I could reuse the head as well as likewise base gaskets. The head screws are presently torqued to spec. Never ever before ran the engine merely torqued it down.

    I NEVER reuse a gasket. My time is worthy of a lot more to me than the price of gaskets.

    That being mentioned, you should be fine.

    As long as the engine has in fact not been run, they will definitely be fine. I torqued my very own down 2 or 3 times each whilst examining valve-to-piston as well as likewise squish clearances, as well as likewise never ever before had a concern with leaks (I got in touch with Dan at NRHS at the time, as well as likewise he acknowledged it’s fine to do).

    I merely did the leading upright my 883 to 1250 renovation as well as likewise accept steelworker. You can re-use the head as well as likewise base gaskets as long as you do not start your engine.

    Numerous numerous other posters listed below have actually mentioned the precise very same factor, ok to reuse. I too asked Dan as well as likewise he validated the precise very same, fine to re-use. This was my first HD leading end so I also e-mailed cometic. They responded actually promptly as well as likewise mentioned the precise very same also, as long as the engine is not started it is fine to re-use head as well as likewise base gaskets likewise after they have in fact been torqued.

    I too torqued, taken apart, restored, as well as likewise re-torqued as well as likewise presently have a very sturdy, leak-less, racer sportster.

    Hey Nate, what did you forget?

    Someone help me acknowledge why a MLS head gasket would certainly not re-seal. likewise IF the electrical motor had in fact been started, as well as likewise probably also about temp!: wonderlan: wonderlan

    As long as the surface are neat as well as likewise degree. I think it “requires to” be fine!

    That’s MY perspective as well as likewise up till someone notifies me they tried it as well as likewise they actually did not seal. (:( I’m sticking with it!:p:p

    Normally everyone acknowledge what viewpoint look like. right!: laugh: wonderlan: wonderlan

    Myles,
    I believe I was thinking a lot more worrying the head gasket than the base. I still think if you would definitely run the electrical motor as well as likewise be actually careful attracting a head, so as not to interrupt the base gasket a great deal, if whatsoever, they “should” re-seal.

    REQUIRES TO HAVE. widely known last words as you start the disassembly to transform them. doh: laugh: laugh: laugh: laugh

I have in fact never ever before needed to re-use the head gasket, nevertheless they can be re-used as well as likewise, in your circumstance where the engine hasn’t been pushed whatsoever, I ‘d definitely use the gasket one more time.

    The head does require to be super-smooth when establishing the Cometic gasket (the provider offers a number) as the steel sandwich is unrelenting of any kind of sort of roughness nevertheless, as quickly as equipped, it’s never-ceasing(!).
