Machine Shop, O Ring head

[9guy9]

Anyone have experience with a machine shop in the area that has cut their head for O ringing? I called a couple places in Mankato and got a long pause followed by a "we don't do that here".

My brother knows a few different people that have done his 12-valve cummins heads, I'll post em up for ya when I get ahold of him.

thank you

I called Gosh and he said he hasn't had to do it for anyone around here so I don't need it and then followed by saying he doesn't have the tooling for it, but he could do it but be ready to pay for the extra time.

That was a few months ago.

I talked to him recently. He is setup and able to do it. But it is expensive if that's all you getting. If your already getting a bore it's very cheap.

Whats the point? Unless your head/block surface isn't very flat, a MLS should be more than enough.

But, you may be shooting for tractor-pull boost levels.

Im surprised dsmers havent done this more often with the boost levels some of you are running.

I've heard of shops in other parts of the country charging about $40 per cylinder.

Blechinger Diesel, is the place that did Cody's motor. It is in Ham Lake. (763) 434-7050

Diesel shop for the win!

If I recall correctly, I had it done for either 20 or 25 per hole, but it was done to my block. I might be able to dig up a receipt, but you maybe can call the shop I used. It's the Carquest machine shop in Hopkins 952 935 0120, ask for Joe.

So all this talk about ringing the head or block... what do you use for the ring then?

stainless or copper wire. I am planning to use stainless wire with a cheapo composite head gasket.

[FattyBoomBatty]

That's what I did. Stainless steel "safety" wire. Then a regular gasket. But I surpassed my old boost level (by one psi) and it held together, so in my mind it works. The true test will be 30psi. Also, I think it would be better to o-ring the block since it's probably easier to get the groove centered on the bore. With a head, the bore centers might be slightly different than the block or inconsistent from hole to hole.

I run 35+ psi with a Fel Pro Permatorque and Arp L19's. Unless you are running crazy ass cylinder pressure, you dont need to o-ring your block.

Proper preparation is the main key, make sure your block and head are straight and your good to go.

$200 head gasket, no

[blackrosenova400]

Well you have to play to play sometimes....

Plus you missed the fact I said.....

Preperation is key!


I see diesels everyday at work that run 30+ psi of boost with 18:1 compression, and they have composite head gaskets!

i'm planning to pay a machine shop. I like the idea of running a more forgiving better sealing composite gasket, with the o rings to provide the combustion sealing power of a mls. I am using L19's.

[Super Bleeder!!]

Brads car runs 30 something psi plus a 100shot with the permatorque and L19s. At least i think that what he has.
