I have the liberator egr delete which keeps the egr valve in ... no block off plate. also has arp head studs. both were done at a dealer 2 yrs ago. the truck is an 06 6 speed manual and 87 thousand miles. i noticed when it was pukin that the coolant is a rusty color like you cant see thru it. do i have bad head gaskets or am i forceing coolant thru the egr valve? Also i noticed for the first time today that i didnt have any heat. then it started to work latter on.Any help would be aprecieated.
So you have the EGR cooler deleted but left the EGR valve in place? If so you might have the start of a head gasket issue. If you were still using the EGR cooler I would guess that the oil cooler is restricted starving the EGR cooler and making it flash boil, which would cause excessive coolant pressure.
If you don't have the EGR cooler then it can't be that. If your coolant looks rusty you have an issue there. I'm sure the oil cooler is plugged up, and probably the heater core.
You need to rig up a coolant pressure gauge and see how much pressure you're building. Also have EOT/ECT deltas. You are probably also going to need to do a VC-9 or Restore+ coolant system flush and try to get the rust deposits out of it. Do this before you replace anything or you'll just plug up your oil cooler again. Also a coolant filter system would be a very wise investment.
