What Head Gasket is Best for You?

[@notwho84]

I like welding my heads on makes them never blow out 😂😂😂

[@chillville2938]

That's an idea 😂 just need a grinder after xD

[@badgermetal]

I considered doing that after I broke a head-bolt deep inside a Subaru block. In theory, the shrinkage while it cools down would keep it pulled tight.

[@meanmachinesgaming]

Flex seal

[@DAMN__________]

Ducktape worked like a bomb too

[@kcdesignconcepts5216]

I have been running the cometic mls on my 3L M50 BMW at 26 lb of boost for years. Using the eaton 2.3L supercharger. It's mainly a track car so it sees prolonged abuse. Never had an issue with head sealing. The key is proper head and deck surface. Head studs help.

[@angelo_giachetti]

And the tune.

[@MR__JUSTIN]

​@@angelo_giachetti Even with a perfect tune, an engine with high power density is going to make a ton of cylinder pressure. Gotta keep that pressure where it belongs.

Awesome info Mike!!!

[@eatmorechicken1064]

I have personally ran 25lbs of boost on a composite gasket and know of people that have ran 40lbs. This was and is still being done on the 4g63. If I was more knowledgeable regarding tuning I would have pushed harder. Downside is any detonation will blow the gasket. Currently running a MLS gasket.

[@xhames61x]

I like good head.... gaskets

[@SpecialAgentJamesAki]

I really like the fel pro SD/marine head gaskets

[@circletech7745]

The best head gasket is the one that doesn’t blow again

[@Brittvanegas]

I use a copper gasket with copper spray and ring

[@motoiq]

I have found that to hold cylinder pressure well but to weep coolant.

[@angelocriniti]

Hi Mike! Do you have a recommendation for a brand that makes a stopper head gasket for a KA24DE?

[@motoiq]

Apexi

[@angelocriniti]

@@motoiqThank you!

[@angelocriniti]

@@motoiqI just reached out to Apexi, they said they don’t offer any head gaskets for the KA24DE. Do you have any other suggestions for a stopper style head gasket for this engine?

[@motoiq]

Whoops I meant Tomei makes sure it is Tomei japan not usa

[@angelocriniti]

@@motoiq Thank you for the follow up reply! What's the difference between Tomei Japan and Tomei USA with this headgasket? (Also, with a quick look at Tomei Japan, it looks like they don't have any parts for the KA).

[@Rideordie-eli]

Can you comment on the IAG Firelock Gasket please? Is it worth it? I was told by OF Motorsports that the blocks machined with that gasket can’t be reused which seems like BS. I asked IAG and they said it just needs resurfacing if heads are removed after initial install.

[@motoiq]

I sort of think that the ring is pretty good and once the block is machined for it, that's it but I have never tried it.

[@michaeldixon6619]

Can you get those gaskets for all cars

[@motoiq]

no

[@Guitarguy0522]

What about feltpro gaskets??

[@motoiq]

For a stock engine with stock type driving they are fine. Not for a modded engine and racing.

[@John.ThirteenPoint6969]

Subaru guys take note

[@williamlock2984]

Absolutely what i was thinking. Subaru got the worst design as far as the water flow goes. The water stays at the top, causing the old antifreeze to eat away at the gasket. Change antifreeze and use the right antifreeze called for the Subi

[@DBOOKIN208]

*Composite is garbage waste of time and money*

[@motoiq]

except for old stock engines.

[@glenbenton4855]

Head gaskets are an absolute night mare now a days considering all work is incompetent everywhere and no one takes accountability. Might as well weld them on or super JB weld and never have a leak lol jk though, not about the incompetent machine and automotive work out there

[@markrich3271]

Us diesel guys run orings . One of my trucks with compounds 110psi for many years no issues.

[@BWalker-yg9en]

You know what the real best head gasket is? Whatever they used 30 years ago in my yj 2.5 because I've been throwing boost at that poor 200k mile engine for thousands of miles and it just keeps on going. Runs like a champ. It still isn't a powerhouse but i can merge onto the interstate without getting ran over. That's always a plus.😂

[@station08]

I bet this guy never blows a gasket. 😅

[@kamperformance5281]

There is also the "Athena/SCE" Composite-Fire Ring Combo Gasket that doesn't require any grooving or particular surface prep.. Like the Last "Carbon Fiber" one you showed us , it features a thin edge in the ring that inserts into the head itself sealing the combustion chamber

[@uses0ap]

How about copper gasket's its a bit old but still my go to i make them

[@Travis_cerny86]

What is the second to last gasket with the inner seals on the mls one and what company

[@motoiq]

Apexi

[@s.v.gadder1443]

Definitely not called sealing rings lol

[@motoiq]

ok cooper rings

[@DeVoNmotorsports]

Hi A composite or MLS based material gaskets will isolate heat. But if you use a copper gasket its soft and will crush and seal very well under higher boost and heating conditions but it does somtimes require additional cooling to the cylinder head with pvc cooler air recirculation/catch can filter, stronger rad fans, and lowering engine bay temps by wrapping exhaust and installing cold air intake

[@motoiq]

I have never gotten a copper gasket to long term seal the water jacket. I have tried coating them with everything known to man and they always eventually weep. They seal compression fine, just not the water after many heat cycles. I consider them to be drag race or short term use only.

[@DeVoNmotorsports]

@@motoiq it should be preventable? why does it weep, corrosion? use better coolant, heat expansion and contraction, use better thermostat even 2 temp sensors with electronic valve, and electric pump to run after shut down, maybe a stainless fire ring around the area like the kind that is a c shape and folds around the edge in a groove, if your heat cycles are overheating the engine that's why it would fail and only if the coolant is overheating from heat soaking, there is coolant you can get that is waterless and inert, maybe retorquing the head would help after heat cycles, copper compression fittings work good and are used for many industrial applications, they have a good yield strength to tensile strength usage without degradation to compression over time so my guess would be oxidization

[@motoiq]

That has nothing to do with copper head gaskets.

[@DeVoNmotorsports]

@@motoiq why does it Weep? you said they weep?

[@motoiq]

If I knew mine wouldn't! Technology makes gaskets that won't blow out and seal better nowdays.

[@erickbernard8208]

What about copper head gasket?

[@motoiq]

The always seem to leak coolant, drag race only.

[@73notch]

Besides the extra machining involved, are there any downsides to using sealing rings?

[@motoiq]

The grooves have to be done with precision

[@Malficion]

​@@motoiq With the number of heat and cool cycles on a street car, do the head studs need to be regularly retorqued?

[@motoiq]

No

If i put in a stock engine will it last longer? I'm not an engineer or mechanic. Im just wondering if it can get more life out of stock engine.

would the iron sleeves in an ez36 be a good candidate to be machined and ring sealed.

Who's T-spec

[@Baconmcmuffn]

due to economic reasons my uncle Bob an ex merc mechanic bolted the exhaust headers onto a 3.8 ecotec v6 without the gasket..does the 2 or 2.5 mm thick exhaust gasket affects the exhaust flow as the the flow length is alterd

[@motoiq]

It's gonna leak, really soon.

[@Baconmcmuffn]

this was over a decade ago Sir and it did sounded more robust and there isnt any leaks i noticed as the surfaces were cast iron and flush

[@motoiq]

If its cast iron, they are not headers

[@Baconmcmuffn]

@@motoiq well its the original stock exhaust manifold..anyways it felt better and he said its should be fine..

[@Baconmcmuffn]

i m quite sure the exhaust outlet vane length affects the flowrate

[@adampancechowski5965]

how do coper gaskets stack up? CAD your block, print it 1:1, glue it on a sheet of coper, few hours later of hard labour you get a gasket? 😂😂

[@motoiq]

I have never had one seal coolent very well, they weep. Drag Race use only for me.

[@oliverscorsim]

No copper options lol I know I'm old-school but I can make it at home and it has yet to fail me even the little compound bike runs one 😂. I do like your options

[@motoiq]

I have yet to run a copper gasket that doesnt weep coolant no matter how you coat or treat it.

[@oliverscorsim]

@@motoiq in all fairness the only time I needed to was the compound bike and its air oil cooled 😂 but I did put one on my neon and it has yet to weep although it's a block and head I machined as well as I could and we annealed the crap out of it. Probably helps that I didn't want to chance it and put a little Indian head around the coolant passages lol and a iron closed deck block. Now on my Volvo I go s60r MLS but we all know how hard keeping a head gasket on one of those t5s can be especially over 500hp even with pd150 diesel head bolts and devcon filled deck 😂. Hell long ago I think I was 16 I had a turbo Honda d16 civic and eh well I was broken and I had cardboard hahaha that lived at 250hp until I sold the car no fire rings or anything either.. looking back that was questionable to say the least but it did work well for the 2 yrs I had it. Your not wrong at all though even with the bike doing a heat cycle and retq then doing it again and again gets old but by the 3rd time I find they don't move much and we check em every few races or Dyno pulls.

[@motoiq]

Man I tried Indian Head, Copper Coat, Gasketsinch, even hylomar and never could get them to work in anything except air cooled engine. Seems to seal combustion just fine, just not the water.

[@oliverscorsim]

@@motoiq interesting thanks for your knowledge still impressed you reply to this many of us 🥲

[@jimmicrackhead12]

Carbon fibre gasket- lol they don't work 😂😂😂😂

[@motoiq]

You need to pay attention, this gasket has cooper rings and can take 100 psi of boost.

[@knowntalker135]

I'm sure you know but how precise and clean the surface would be with no gasket like the subaru sti hoonicorn aka the subicorn

[@kh40yr]

No matter which one you use, always hit them with 2 coats of K&W Spray Copper Coat, both sides, and let them dry 24hrs after the final coat. I usually do this weeks in advance of use. I have brought old, dead, head gaskets back to life with Copper Coat. 1 reused, regooped, gasket has 875K on it. Your welcome.

[@nzuncovered1845]

I heard race teams use Hylomar spray

[@motoiq]

I have found that not to work either.
