O-Rings, Pictures, Myths, Facts and Info!
Just figured i would post a thread that could easily be found for people searching for info and pics about O-ringing their heads...
First some facts and fiction;
Here are pictures of my O-ring job done by Advanced Sleeve in Mentor, Ohio.
450$ Later (Machining, Cleaning, O-ringing)...
400$ Head Studs, You should NOT use head bolts with O-rings...
Any questions? Just ask!
First some facts and fiction;
- An O-ring does not have to be installed in the engine block
- An o-ring does not need to have a grove cut in head AND block
- An O-ring can be glued or more correctly pressed into the grove in the head
- An O-ring is nothing more then a piece of wire put into a groove on the head that gives extra clamping force directly on the fire ring of the head gasket.
- An O-ring protrudes past the heads surface to establish the clamping force.
- O-rings require many heat cycles to clamp the head down to proper torque
- O-ring wire is cut and filed down for a tight fit in the head
- The gap on an O-ring should be near a head bolt to help keep it tight.

Yes, in combination with head studs the rings help seal up things to over 75psi. I stretched my stock bolts and poopped the head gasket @ 35psi (and smill high boost spikes to 40psi) with the stock turbo. I ordered 130hp injectors and will probably have twins in spring. So it will need to hold strong.
