I don't normally comment on videos but will do so purely to help the algorithm bring you riches. You consistently make high quality videos, even out of normally boring topics like combustion sealing.
In 12v BMW engines it's common to use a combination of a stainless fire oring in the block and an OEM composite headgasket. It makes for a good combination of OEM reliability in sealing the wet deck and performance head sealing with the oring system.
I use fire rings with a composite gasket. No groves in the block though. Best seal I have gotten on a vg30 (300zx engine) and I have had a few issues with sealing at my power level
Yea i just used the oem nissan hg, composite with the fire rings over each piston and all the coolant holes ... As long as you aint detonating or using too much boost for those head studs, that oem gasket will hold.
@@ACommenterOnTH-cam i get the composite gasket made to get the correct thicknesses and recently upgraded to 625 headstuds. Zero leakage with aluminium bronze fire rings at 40psi. Just bent valves instead this time.
I had used an mls-cometic back in the late 90's .... when i rebuilt the engine, they were on back order for several months so i had to go back to oem composite. But it was funny that the oem composite had the crush rings built in where the pistons were and all the coolant holes.
What about the head gaskets that use thin fire rings, but don't require block machining? That's what I use on my engine, it seems like the best choice since the rest of the gasket is composite with rubber sealing rings for oil and coolant, but still gives a great seal at the combustion chamber. The only downsides in my opinion are they cost double what an MLS does, and the head has to be shaved about 0.005" every time you pull it due to the grooves caused by the rings.
you can have the best of both worlds, we use a mls gasket with al/bronze fire rings. (custom edm cut mls gasket to suit the rings) abit like a athena composite deal, but using al/bronze gas rings instead. seals everything.. no combustion leak, and no oil/water leaking either. literally blow the side of a 2j block apart and still have an intact fire ring. abit expensive, but its a multi use for the life of the engine gasket solution. have held 2500whp in a full wet 2jz. retaining factory water pump and radiator. no leakage of anything. if you must have a wet deck, this is the ultimate solution.
I'm sticking with the OEM stock MLS HG on my 2JZ build. Have seen many hold over 1000whp with no issue. Fire ring might be good for someone whos building a 2000whp car but for most the stock MLS is the best option.
MLS gaskets have been around for years. Many older engines had them. They knew how to machine accurately before WW2. The WASP aircraft engines didn't even use gaskets to seal the two halves of the case.
Factory Ford Boss 429 Engines were dry decked with individual registers for separate fire rings and cooper ring seals for oil and water. Pain in the butt to install and assemble engine. Jon Kaase solved this issue when he introduced modern technology Boss '9 cylinder heads for 429 and 460 385 series Fords. Conventional head gaskets can now be utilized.
I love that the verbage is very thought out and understandable for anyone with lawnmower experience all the way to expert. Maybe next he will do one explaining exhaust manifolds, and probably show a eBay sheet metal twin scroll, SPA cast equal length twin scroll, and a FULL RACE. Weight comparison, durability, price?
Good video. Have used almost all those types over the years. currently am trying a oem compsite with SS O rings in the head on my 4g63. If that fails I’ll go back to the ole HKS MLS.
I have had 2 FelPro MLS gaskets fail on on a head/block with very slight warp. The machine shops say to only use MLS. It seems like a Composite/Graphite Gasket would be more forgiving?
Did an overhaul on an older 2.0 litre non turbo diesel engine, my mechanic says he wants to change to a carbon gasket as the steel one he chose is not sealing well and the engine will overheat.
Unfortunately I was in a pinch and needed/wanted the engine assembled and the only available type for my engine with the compressed thickness I needed for my target compression ratio was composite. I wanted MLS.
@@realstreetperformance good to know! Even for a clapped out 1997 GM LT1 V8?! It's a basic but old combo. Forged rods and pistons, ported heads, cam, Vortech blower, converted the distributor to coil per plug and run it on a Holley Terminator X meant for an LS lol.
Hi I have an over skimmed Toyota Corolla 3T cylinder head, when I fully torque it the engine stops rotation. Which kind of gasket can I use to restore the cylinder head to the standard surface.
I have a Ford Ranger 1993 v6 3.0L 4x4 XLT, does this engine requires a specific head gasket? I read that a RWD needs a left and right head gasket, and a FWD it does not matter which way is installed, meaning the two smaller coolant slots on both ends are opened. Is this accurate? Any information is appreciated. Thank you
I see you are in Sanford Fl . Do you visit Palm Beach international raceway I’m in west palm and have a diesel performance addiction lol could be worse
hello how are you ? hey I own a Toyota 1fz fe engine and I planing to replace timing chain, head gasket, etc etc , the engine is working perfectly right now, but my question is, do I need to sent the head to a machine shop in order to install the new head gasket or can I just put it back as is ? thank you so much for your opinion
Hi, If the head gasket is currently sealing well there is no reason to replace it unless you are looking to upgrade for future modifications. If that's the case, yes the head will need to be decked to the appropriate surface finish for the gasket you are planning to use.
Another downside to a copper head gasket is that the sealing spray is ultra carcinogenic. It's cancer in a spray can. I use a respirator and spray them outside. In all other ways, I like copper. I've machined them myself on a custom application where nearly anything else would have been impossible.
My mechanic said my engine uses a copper head gasket. He said my block was machined for the O ring seals. I asked if the heads had been machined for the O ring and he said no. Is this possible??

My nissan oem gasket is composite and has the fire rings on each piston and over each coolant passage.
@@ACommenterOnTH-cam It has the rings that you can actually remove from the gasket, and are grooved on the head side?
Would have been nice if you covered cut ring style gaskets like that of SCE
That's what I was thinking
I love these videos. You guys are amazing
Thanks you, James. 💚🙌

@@tadda6282 yes. Stock gasket is fine for 1000 engine HP. But since we are in there, doesn't hurt to future Proof it.

Today in Brasil everybody uses Fire ring, are cheap and safe for use on VW 4 cylinder engines
I know from many different sources that the stock Toyota 1JZ head gasket can handle 54psi. and over 1100hp. 😎👍

Which do i get for my rx7
Composite fire rings. With MLS timing belt. With exhaust valves made out of The highest grade Chinesium.
Ya mom
Lol
The one that comes with completely assembled 2JZ or LS.

Love these vids, always learn something!
What is the black stuff you used to seal the copper headgasket? You mentioned copper spray and other things. What are the other things? Thanks
I have heard of people using hylomar used on each side of the copper HG to seal the water jackets and the oil passages.
Awesome video! Thanks
Not bad video. How would you compare the Fire Ring Gasket to the Vulcan?
What are the pros & cons?
Just fire ring hoop including the passages
I wonder about the jb weld head gasket
Waoooo thank God I came across this channels

On modern common rail turbo diesels would you advise to spray Hylomar onto gasket prior to installation?..
Supper info thank you Sir

Might be a bit late but what's your opinion of the Athena cut ring head gaskets
Very,VERY Helpful video series you guys have done!! Thanks much!! I personally took some notes and screenshots. 👍🏻👍🏻👍🏻👍🏻
Can it be used more than trying the head gasket MLS?
With a sightly damage head and a three-part headgasket should you cooper spray it?
For 4g63t to make 1200hp at 50psi what would you choice? How about using SS head ring and MLS gasket?
I use butthead head gaskets they seal good they leave a brown residue tho.
What gasket do y’all run on your white Supra Jay? And what gasket does JR run on the green Supra?
Hey mike. We use a copper gasket with a fire ring on both of those cars.

Is it ok to use copper spray on composite headgasket to "increase its grip" and make it seal better ?
Jay, whats your normal coolant pressure with copper gasket ?
Thanks !

I was just looking at 2jz head gaskets I went with a 86.5 bore so would I be good with an oem gasket?
Yes. I did that with my engine, bought the whole gasket kit from Toyota. 👍
