Nope just watching the gauge in dash and on the edge. As far as I can remember though its always been like this. Any idea what your trucks pressure runs Jamie>?

Yea that looks exactly the same as mine! on a rev cold it will damn near hit the white line! Thanks for the pic man and that looks to be about 75-80psi to me!

Yep, your pressure sounds like it is exactly the same as mine. My new camera phone is awesome!
 
Looks good! I believe my head gasket took a dump and not the oil cooler. I;m getting the cooler pressure tested at the cummins shop tomorrow, they have a plate to test them specifically I found out today. So if its good the head is coming off tomorrow night!
 
Headgasket Carnage for sure. Had the cummins shop pressure test my oil cooler today it was good! They actually have a test plate just for the oil coolers(nice to know) All so found some other interesting things inside. On cylinders 1-3 I seem to have some valve to piston contact. Very minor, just enough that I can see an exact indent of the valve in the piston but can't drag a finger nail across it and feel the indent. Has me worried, Guess I'm gonna look into getting the cam degreed. Thats the only thing I know to do. Any ideas are more than welcome! BTW the gasket blew back a cylinder 6 on the drivers side!

I'm wondering if your valves being out bad enough to cause your truck to surge had something to do with that.
 
Well I'm thinking not. The valves were only out a few thousands. I've played with different lash since I put this thing together though. Greg Houge had me set them very tight and I have since put them to cummins specs. I think I really need this cam degreed. Just need someone with the knowhow. When I got the cam it was supposed to be a direct drop in then I called when going to install and was told to degree it. I had no resources to do that so he told sent me the most extreme offset keyway and told me how he wanted everything put in.
 
Glad you found the problem man but sucks bout the piston and valve contact. Cam degree is very strenious form what I have herd. I was gonna do it on my Lt1 350 when i did a cam but decided against it cause I just wanted it to run good. Now if i had a built motor I would have.... Would degreeing it make that much of a difference? And did you have your head planed when you had it O-ringed?

I believe its goin to make a good bit of difference and so does the cam builder. Should be able to move a lot more air at the right time when degreed propperly

Ok, I have never been in a cummins engine like I have a 350 or the old paper weight 6.2 diesels but would my pistons look like that? To me it looks all sooted up, that just cause of the heave fueling?
 
I have the same problem right now. My coolant looks like straight oil. But no coolant in the oil. Guess its time to pull the head :bang
