[@ZeroTo60Tube]

@@shafieksalie3119 there is a lot that goes in to keeping the cylinder pressure in the right place. Sometimes too large of a bolt and too mention tq on the bolt can twist the block and cause more problems. This is a test in what this style of gasket really does, when being used by itself. Taking out other variables.

FINALLY n54 content. To hell with the athena cut ring, you straight up need an o-ring'd head. CSS + sleeves if you want a chance at surviving 1000+ HP. Lots of reported failures on the elring gasket, BUT to be fair, the deck and head surfaces have to be absolutely perfectly flat and finished to the correct surface roughness with a profilometer. If you aren't doing that, you will push coolant, especially with no o-rings.

[@diyguy6054]

If you can reduce pumping losses. You'll make the power with less parasitic loss. Higher volumetric efficiency means potentially less pressure and heat. By this I mean porting the exhaust and adding some aftermarket cams. Intake ported as well. It works on other platforms. In fact it's probably the one of the reasons why one of my LS based builds has lasted so long. I tailored the heads to the build (positive displacement setup). It made more power with less boost than other identical builds. Combined with a slightly looser converter. The car has lived way past most others experation dates. If you make the engine more efficient, it'll decrease back pressure, decrease heat. Because the turbo won't have to work as hard to nor will the engine have to work as hard to move the same cfm.

If that made any sense lol. MY OEM engine is holding well so far with basically the exact type of build you had with the cheap 17T build.

Drop a link to the new head gasket

[@T.Cun.]

Proper fire ring and copper gasket is the way.... Steel compression strips around the cylinder will not deform enough to allow the fire rings to bite. Also check the copper gasket is annealed properly.

[@cbdrift]

i saw an open deck block where the engine builder drilled a dowel hole, so a round dowel pin slides into the hole a few inches, with an overlap on both cylinder wall and block - so the one round dowel pin locked that part of the bore and the block together - they ran a few of these spaced evenly around the cylinders - and being metal they would not allow movement between the open deck cylinder and the block. You could flush fit them or you could recess them depending on what your head gasket needed to cover / seat on. It looks like your cylinder walls are similar thickness to the one i saw - which was not on a bmw. maybe an option?

[@rare7385]

Hey Andrew, great to see you getting back to the N54 content. My thoughts on the Athena racing head gasket are positive. (Currently planing a few mods on my m235i and have been researching it for myself). As long as the head and block are straight and true the gasket should hold up to about 50psi. Although my understanding is exhaust manifold pressure has an influence on this. I would combine the cut ring gasket with head studs and deck the block and head etc. Quite interested to see how this one pans out!

[@tighematthew]

I have been running the Vulcan cut ring gasket for the n54. No problem yet

[@ronn147]

Loving the content! I’m used to dealing with v8s but I enjoy learning about all different makes and engine builds. I had a thought and if it’s a crap idea for your build then just disregard it. Have you ever heard of or watched any Steve morris videos? Big v8 high horsepower guy but when it comes to o rings for head to block combo he seems to have a really good system. He puts the steel ring in the head and groves the block then uses a copper head gasket to “squeeze” the gasket into the groove in the block for maximum sealing. Just thought I’d throw that out there as another possible idea to seal the cylinders up and maybe not cost an arm and a leg lol. Good luck. I’ll be following along!

[@ZeroTo60Tube]

Yeah, I enjoy Steve’s videos. That ring is the “real” way to hold combustion pressure in. I’m still playing around with this motor build. Definitely not the best way to go a n54, but some more experimenting like the old days.

[@ronn147]

@@ZeroTo60Tube good luck! I’m curious what you come up with!

[@Jam24711]

I highly recommend you still go with ARP hardware since BMW head bolts are torque to yield and that could mess with the cut rings properly sealing and cutting into the head / block.

[@ZeroTo60Tube]

This was a concern of mine. Also why i checked the break away tq required to remove the last stretch bolts (these would have seen around 700whp and potencially the head lifting). The "main" issue is the cost of going to an upgraded stud. The other point i didnt clarify enough in the video, when you use studs and change the factory head tq values, we dont really know what effect that has on the entire structure of the block. Papadakas did a great video on the B58 recently. He summised (loose term here) that the factory B58 bores are not straight until they are bolted down. To the point he said if this brand new OEM block was recieved this way from a machine shop he would return it to have it redone. He believed the factory are maching defects in to the block which correct themselves when torqued down. So in the inetrest of trying to be scientific. I wanted to see what would happen with this style gasket and factory torque values on the head. Ive seen unopened n54 engines roll 1000whp. Massive single turbos with a very thin power band. But the factory head gasket will hold for a little while. I've also seen a few blocks crack where the ARP bolts have been fitted. Obviously to get a decent stud in there you need to time sert as factory thread in the alloy block is limiting to a point. But then if you time sert the amount of material around the time sert is also quite thin. There is a lot that goes in to making an engine work at 2/3 times its intended power level and not many people understand all the aspects of each potencial upgrade. There are hardly any N54 engines out there that get used for prolonged periods above 850whp. Nearly everything breaks pretty quickly. Im trying to piece together a puzzle of everyones results and combinations interest of a combo around the 800whp level. Which lets be honest is more than enough for these chassis.

[@cornfedboost]

Those cut ring gaskets make a big difference on a closed deck engine, so it will be good to see how it goes on an open deck one

[@ZeroTo60Tube]

Its something i wanted to investigate. I havent seen anyone try this combination. Also kinda clutching at straws with stock headbolts. They seem ok around 750whp, its almost like they have a little give as everything is hot and expandting/twisting. Where ARP dont really do that.

Finally

[@liftedcj7on44s]

Have had 0 luck with those gasket's at my job, We mostly do Evo's,GTR's and Lambo's. Our method is Copper Gasket with a fire ring. For the N54 I would keep the Factory MLS, Do a stainless steel wire in the head and ARP head stud's. That method should crack the sleeve before the gasket blows.

[@ZeroTo60Tube]

What power levels per cyl were the ones failing? What you are saying is 100% better, but also quite costly.

[@liftedcj7on44s]

@ZeroTo60Tube On a 4G63 around 1200whp or higher is when we do a copper gasket and fire rings. On a GTR it's around 1800whp when we start doing the same. With Evo's we can usually keep the headgasket happy with a stainless O-ring in the head on a factory MLS gasket up to around 1000whp. Copper O-rings do not work as they are too soft. Now keep in mind an open deck block changes everything. If you know about Myles Integra we run dowels on all the head studs.

[@ZeroTo60Tube]

@@liftedcj7on44s Those examples are way above the power goals i would like to see. I am curious about the integra setup with dowels on all the head studs. I feel that would help reduce twist in the block fairly significantly.

i can tell you one thing that influences more than any of the things you mentioned TUNE! remove torque because you don't need it with such an efficient gearbox-really wind back the torque under 4.5k and this won't happen again MLS gaskets do 35psi easy! if you were making 700nm make it 500 skim the head properly this time! also you will flex the block if you use ARP to its maximum torque. don't go over 15% torque to standard if you can shorten diff gears, this helps engine load allot also

[@Jeff-bw5kw]

Andrew, first, great to see hard-core N54 content. Watching the time-lapse of your taking off the head was pure rapture! Second, I see FCP Euro sells both Elring “OEM” and Genuine BMW head gaskets in two thicknesses - “stock” and “1.52mm (+0.30) Thicker Than Stock”. Which thickness had you used, and any thoughts on choosing one over the other? Third, the comments about tuning to keep torque (and hence cylinder pressure) low at low rpm seems to make a lot of sense from an engineering perspective to help minimize cylinder deflection. It would seem that a given pressure in the power stroke, a cylinder will have more time to deflect at low rpm than at high rpm.

[@ZeroTo60Tube]

The thickness of the head gaskets generally come in to play when surfaces have been machined. The thicker gasket then makes up the difference in the combustion chamber. Previously i used a stock thickness. Factory gaskets are identified by holes in the corner of the gasket. The Elring runs a difference hole numbering system it seems. The elring is definitely not the same as the genuine MLS. Regarding the "tuning" this is very evident with big single turbo N54s. They cant make power down low due to the lag, which is why they seem last at higher peak power levels than the twin turbo cars.

That head needs resurfacing. Modern engines are cast with hardly any strength, over heating will cause distortion. You will also need to straight edge checks on the block especially where the gasket blown

So the issue is head gasket sealing. I agree budget is considered but why not just do the block insert with the copper o ring? The o-ring does not keep the cylinder wall stable the block insert does.

Did you ever find out why the motor was originally knocking?

[@ZeroTo60Tube]

This motor never knocked. The built one however…….. it had a loose bolt on the power steering pump. It was insane how much is sounded like rod knock.

[@maxcutie822]

@@ZeroTo60TubeAwesome thanks for letting me know. Do you have any recommendations for upgraded main cap bolts/studs?

[@ZeroTo60Tube]

@@maxcutie822 I dont believe that would be needed. Theres a few engines running over 1100whp stock main caps and bolts and staying together........ for now.

Using such a thin cut-ring to keep the liners in place is quite risky imho. Machining the top of the block and pressing in an insert may be a bit more expensive, but should be way more reliable. Even cheaper pinning of the cilinders with alu dowelpins at the corners is a much better Idea.

[@ZeroTo60Tube]

Accurate statements. But I want to see what the cut ring does vs a mls. See if it’s any benifit.

[@km6832]

​@@ZeroTo60Tubethe results will likely be the same. Then you would have to take the block apart again because you will still have wall flex because of combustion pressures..not my money but if you want to experiment on it more power to you

Those Athena gaskets are notorious to leak coolant out through the matting surfaces wouldn’t recommend, oem gasket and a good machinist is all you need

[@Glo_Natee]

im gonna run oem gasket, stock head bolts, epoxy, with only head resurface. I'll see how it goes

[@ZeroTo60Tube]

I think that is a fairly safe, tried method. Hopefully it serves you well. What pistons and rods are you using?

[@Glo_Natee]

@@ZeroTo60Tube cp pistons and brian crower rods

you ever used those Metal intake covers from china?

Do you mean the inlet manifolds? ]

@@ZeroTo60Tube sorry, I meant metal valve cover

[@ZeroTo60Tube]

@@rllamas14 i dont see any advantage. They do exactly the same as the plastic ones and a new plastic one will last 5-10 years. There are issues with cast alloy being pourus mild concern with the china ones. I guess they are better if you want to paint them. I would really like one of the billet style covers ideally. They tend to really tidy up the engine bay.

[@nickboyco2666]

Will you be using the zd30 head bolts?

[@ZeroTo60Tube]

No, this is purely an experiment. I don’t want to have any extra variables than just the head gasket. To see what it will do.

[@RenÉ_MiG]

Oh Boy !!! cant seee this composite head gaskets holding up to so many more than normal heat cycles...

[@ZeroTo60Tube]

There has to be a reason they exist. And so many well established companies selling them.

Also seen video Indian i gues making head gasket by hand and packing elring labaled package.

Been considering doing an 8 speed swap since revisiting your channel. I don't really see anyone here in the US doing any 8hp swaps or any content regarding it. Got a z3m coupe that keeps eating up slave cylinders. So tired of it that I'm tempted to just tear the trans out and go with the 8hp. The stock gearing on the 5 speed they come with is terrible with the stock rear end ratio. Going deaf on the freeway.

[@mcmillinpead]

id gauge the surfaces before blaming the gasket
