Maybe that would be a good poll- who put your head gasket/O-rings in/on, and are they holding up?

O-Ringing The Head

I had the O-ring register plate tool built for the Cummins engine with the intention of using copper gaskets. This has been somewhat challenging so far. We have tried several configurations with modest success. My engine being the most reliable so far. I run 85 psi everytime we go down the strip and I don't have any major issues so far.

The factory applied sealer on the copper gasket didn't work at all. I have had better results with other techniques.



The best bet is the stock gasket with an O-ring.



FYI, Van Haisley now has an O-ring tool in Indiana as well as does Tom Meers at Black Mountain Diesel.

Nowel,



What about receiver groves?

Did That

Pushed . 022 of copper into the receiver grooves on Kurt's engine. This is on the gasket/head side. It was blowing right past that, big time. The absolute worst I've seen. This O-ring tool I use is deadly accurate and we matched the O-rings with the receiver grooves dead nuts. But apparently the head is lifting more then the receiver groove side will tolerate.

Nowell, thanks for the info on this situation... . you will never understand how much it means. Kurt you are now a test bed, one that Nowell and we will all learn from. "Stay true to your builder and let him learn"
