Today I called Haisley Machine and Scheids to pick their brains on fire rings vs o rings. Both shops recommended fire rings. Neither shops do o rings anymore due to "not having any luck with them". Both said that they have many many trucks running daily on fire rings but it is stated several times in these forums that they are more for race applications. :confused013: Do any of you run fire rings on your trucks n a daily basis? Do any of you have problems with trying to? They almost have me convinced to fire ring but I want your opinions before I pull the trigger.

I ran a truck with fire rings for 2 years no problems, my brother is over a year on fire rings and everyone around here has fire rings. All daily driven trucks too

I talked to the local machinest the other day since he has my head doing springs seats and seals, and he said its almost a waste of time to do o-rings on a diesel because they will not handle the cylinder pressure (not saying they wont last for a long time on a nicely droven truck) but fire rings are just fine on a DD, they will not hurt anything so it is a good investment to go that route if you plan on putting out higher numbers.

I'm running fire rings on mine. My original plan was to have o-rings put in but the machine shop I took it too misunderstood me and cut fire ring grooves in the head. I decided to try it out anyways. Going on almost a year since installation and its holding up very good. Sees 45psi of boost daily and I've been all but nice with it. Just make sure that you warm it up or drive it easy before being hard on it and stuff.

So the general consensus is just what Haisleys and Scheids told me then. I tried to get somebody with East Coast Diesel on the phone to get their input but no one ever answered. Ill probably go the fire ring route. Both shops said that they had trucks past the 100k mark running fire rings daily without problems. I'm not looking to make huge power but I want to only do this once. If I can get 7 or 8 years and 100k out of the fire rings I'll be happy happy happy.

Call Sealtec in Oswego, IL 630-692-0633. They are the company that actually makes the fire rings for all these other companies. I used to work with them. Good people. They can probably cut the gasket as well. They make a lot of custom gaskets and fire rings for the tractor pulling circuit, John Deere, International, etc.

as long as the machine work is done correctly and you let your engine warm up, you should never have problems.

What is a fire ring?

I search on Google and all I can find is metal rings to go around a hole in the ground... YOu stick logs in and burn them.

Difference between o-ring and fire ring(also how they work)

"when you o-ring it, your cutting a small grove in the head and placing a ring in it. then it is placed on top of the headgasket. this way it is putting more clamping force down around the cylinder. this is usually a better method for a street driven vehicle.

fire-ring there is a grove on the block, head or usually both. normally, where the head gasket would seal around the cylinder (aka "fire ring"), that little bit is cut out to make room for the ring to sit in the groves. making it so its just the head and block with a small piece of wire between. its called this b/c your making your own "fire-ring" for the cylinder. creating a much stronger seal. this method is usually more problematic on street vehicles due to numerous heat cycles. this all depends on climate, driving habits, ect."

For those of you in the dark.

? i asked a guy about o rings and he said that they actually do it different over where they are. they said they actually cut the o ring in the head right behind where the headgaskets fire ring is to "back it up" in a way. it reinforces the headgaskets fire ring and still requires 4-5 torques on it? the fire rings in the head are just thicker wire? i'm trying to figure out exactly what to do real soon. could be pulling the head off as soon as this weekend to get the work done.

I went to east coast diesel and had my head oringed one of the owners delton has oring on his sled pulling head .041 stainless steel wire. The motor makes 1200 hp and he hasn't had problems with blowing gaskets so I was had mine (amOng other things) oringed and I was told it was way more reliable with orings. I looked at a lot of the fire ringed heads and blocks and orings is stainless steel wire that's pressed into the head but fire rings are just loose rings that sit in a groove or grooves to seal the head to the chamber better but they crack and need replacing orings are lifetime unless you pop them out
