Have you ever reused a head gasket?

I was reading a few threads on another site about this gasket issue and I was wondering if you ever reused a head gasket or any other sensitive gaskets. I just want to know from people who actually tried to do it, doesn't matter if it worked, failed, whatever.

If you done it tell me the results, what type of gasket it was, why you thought you could do it without incident, the type of vehicle, and how long it lasted.

Back in the day. Used solid copper gaskets over many times. Doing quick checks between rounds at the drags.
Also have used steel shim and Fel-Pro blue gaskets over on SBC engine in dragster. Never a problem. I had a gasket engineer tell me Chevys can be sealed with almost anything because of five bolt holes around the cylinders.

My shopmate is a one of the few top fuel owner/ drivers left. Yes they still use copper gaskets with wire o-rings in the heads and reuse the gaskets as long as their condition allows. I have not ever reused any other type of gasket. Maybe it will work but I wouldn't know.

Yes, a honda 3.2L v6. It was the factory cometic head gasket. It is composition of metal plates and you can torque it again.

Well I am mostly curious just about the results with gaskets that arent known or said to be reusable.

I run Cometic MLS on the blower car, and talked to Cometic about reusing, they say yes if it was sealing when last assembled. Even at over $100 per side I don't reuse them, but then I don't pull my heads that often.

I have head studs and it simply is not worth the effort to have to pull the motor out twice to replace the head gaskets. For the $ 100 or so for a pair of head gaskets it's just not worth the risk.

The Funnycar we reuse the solid copper gaskets all the time. We have sets from .060 to .100 by .010 that are changed to alter compression ratio. Once in a great while a head will get a gouge burned around the o-ring groove under the gasket. It doesn't trash the head but it means a trip the head rebuilder for welding and machining that we can't do. I don't recall ever burning the new aluminum blocks this way. Lost a couple cast iron hemi's in the old days however.

To answer the question, I don't like to have to re-do motor stuff so I'd say don't reuse.

On some smaller old motor cycles. I didn't have the head gasket so I used a film of silicone.

How long did the pizza box last?

Only in the case on MLS, shim and graphite or Teflon coated composition gaskets and the engine has not been run nor gasket goo of some sort been used. I never reuse these type gaskets once the engine has been run. I typically end up reusing head gaskets when doing assembly mock ups where the engine may come together one or two times to measure dimensions such as valve or spark plug to piston clearance, etc. Certainly the higher the output or end use of the engine plays a role, high end builds for street or competition only leave the shop with virgin gaskets.

In the case of copper or aluminum with cylinder O rings these can be cleaned and annealed then reused in their original locations when there is no other choice this being an in the pits maintenance thing. A new build, rebuild or a service tear down and inspection always gets fresh gaskets.

Back in the flathead days I would reuse the copper head gaskets. I have also reused the performance level Fel-Pros, but only if I haven't filled the engine with water, then fired it and run through a heat cycle.

There are several levels of Fel-Pro gaskets. The ones I've reused are the HiPo Perma-Torque versions, i.e. Q1011-1 or -2(which I'm currently using). Their standard OEM level gaskets, i.e., Q9333Pt1 probably I would not reuse, are fairly inexpensive, though these are almost as good as the HiPo's for performance use without nitrous or supercharging

Don't think i would ever re-use a headgasket. Some of the newer motors have reusable gaskets, but they end up leaking over time so I don't know how reusable they really are. I wouldn't reuse any gaskets that are under pressure or hard to get to.
