Been driving around for the past couple months or more with a boost leak. Got a couple weeks off between and dug into it. Put my test cap on and got the soapy water out. Found a good size leak on the upper clamp on the i take horn. No problem just tightened the clamp up. Start hosing the other and nothing. Started spraying the intake cover on the head and when the soapy water hit around #4 it looked like Lawrence Welk has having a bubble party. What I hoped was going to be a 1 hour fix went out the window. I look down between the head and the plate on the intake and I can see the gasket pushed out. Took everything off and find this.

Looks like the gasket seperated. Which after getting it off it appears thats what happened. 

The bolts in that area were tight but not as tight as I feel I left them after the head gasket install. So maybe install error on my part. Though as I remember the gasket appeared fairly thick when I put it on. I was able to seperate it somewhat but it still appeared to be made that way. This gasket was from the Cummins gasket set I bought for the HG replacement several months back. Did not have the Cummins name on the gasket.

 

Lucky for me I have a extra one from a Fel Pro gasket set I bought a good while back. I pull it out and it is the same brand as the one from the Cummins get. Though it is dark tan and not red. It is also not quite as thick as the Cummins one though. They both have the name inter face on them. So I will keep my fingers crossed this one holds.

Is 18 years to long to ask a hose to last?

 

We think you need to be honest here - we are pretty sure that you used that hose as a handle to lift the head from the block during your head gasket replacement.  I know, it only lifted the head out once....

There is really much pressure on the heater hose . Are you sure it blew or rotted. 

Mine stay on with no clamps and can pull them off easily by hand truck blow them off or leak with clamps not on. Yes they're on now but I've accidentally ran without them

I dare say after 18 years it just got tired or rotted. The upper one that connects to the head split across the hose just below the 90.

 

Not sure how long mine was leaking but I blew 3 gallons of coolant out. How long did you run with no hoses on? Seems to me that the heater hoses ought to have the same pressure on them as the rest of the coolant system.

I had heater hoses on with no clamps.
