Ok time for my stupid question, what is the difference between fire rings and orings. I know what orings are but not the other.

 

Hey Keegan, I have that cherry picker here off Beck's Church Rd. if you need it. Give me a call. If you come help me load it, I will bring it to you to use.

Do tell on what happened to cause this so that the rest of us don't have the same misfortune. Hate to see anyones truck busted.

Hey buddy, it is not a stupid question. Let me see if I can explain it to you here where you will understand it.

Firerings are like o-rings but they are "pre-formed" and usually thicker in diameter. As I recall they range in size from .100 to .120 and I believe some are thicker than that too. You can either cut a groove in the cylinder head for a firering, but IMO, the better way to go, is to cut the grooves into the block right around the top of each cylinder. The firering then takes the place of the metal ring in the cylinder head gasket to seal the head.

Hope that was clear for you 74dart,......if not let me know.

To add to what John posted, if you get the new style Scheid gasket like I did they don't cut the block or head for the fire rings.

 

Are the rings incorprated into the gaskett then?

 

No, you set the gasket down, then place the rings inside the gasket.

 

And you dont have to cut the head. I might have to look into that when it is time to change mine again.

 

Figured I would post an update. Keegans computer crashed so he hasn't been able to be on here and post pictures. The head should be on its way to Tim's to get it o-ringed and resurfaced. He is also going to check the valves to make sure everything is ok. We both are keeping our fingers crossed that we will have everything back together for Mopars!

 

Good luck, Keegan!

 

If you drive that head up there yourself be real careful through Lawenceville Va. They like to catch speeders. Don't ask how I know this.

I hope it works out so at least you can drive it down to the Rock.

 

The plan is to pick the head up from Tim at Creswell on Saturday, that should give us more than enough time to get her put back together and try her out. Rodney, how is the work on your truck coming along?

 

Well it is coming along o.k. Hopefully I will be driving it down to Creswell this weekend. If not I will drive a gasser down there. Either way I will be there.
