[QUOTE="Countrycar, post: 1550277, member: 11769"] Hey Guys, I'm wondering if anyone has seen this before and can direct me which way I need to proceed here. Let me begin by saying that about 4 weeks ago I had done an Oring job on my injectors after a no start condition had presented itself and my diagnoses concluded that my injector Orings were bad. I pulled the injectors and sure enough 7 out of the 8 injectors had some pretty bad O rings on them. I did have this goop on the valve covers, but since I had applied Compressed air to the head, I figured that the goop was attributed to the compressed air and didn't think to much of it. I cleaned up the valve covers and I then replaced the injector O rings assuming that I had found my issues but still had a no start. After this, I then replaced both iprs (BTS Hpops) and at this point Hallelujah, she fired up. So I'd been driving the truck around for the past few weeks and on Monday I went out to start the truck and once again experienced a no start condition. I got the Forscan out and pulled codes 1212 and 1280 which pertain to the ICP. So once again I figured I'd go ahead and pull the valve covers and see if maybe on the reinstallation process I'd missed something and this time once more this is what I found, a slimy goop that was stuck to the valve covers, just like last time. No where else in the head was this slimy gunk present, just on the valve covers itself. It does appear to be a mixture of water and oil for sure. My degas bottle was a little low, but I also have a very slight leak from a rubber expansion plug that I used in place of a brass expansion plug after my last repair. Thats a story for another time. So far this is what I've done. I don't have any oil in my degas bottle, or my coolant system as I pulled the radiator plug to verify this. I also pulled the Oil pan plug and removed about 1 gallon of oil from the pan to check for coolant in the pan, and nothing. So no coolant in the pan, and no Oil in the degas bottle, and no white smoke coming from the exhaust. I'm a little stumped here. The truck is a 99.5 with about 55K on a full rebuild. Has anyone seen this before? [/QUOTE]
