Did a coolant flush on the 3.0 about a week ago. Went out today to check the level and found fuel in the coolant overflow tank. I am guessing it is probably a head problem, but only thing I have ever seen with head gasket problems is coolant mixing in the oil. From others I've talked to, I've been given a wide array of possibilities:
1. Cracked head.
2. Blown head gasket.
3. Bad fuel pressure regulator
4. Fuel pump putting out too much pressure.
5. Not possible for fuel to mix with coolant.
The truck runs fine going down the road. It's not blowing any smoke out the tailpipe. At idle she stays running, the RPM's hold steady, but feels like a little miss or sputter in the engine. Starting when cold, she starts up with no problems. When engine is warm she acts like she has a dead battery when trying to start. Have to hold the accelorator to the floor to get her to start. No problems with her overheating. No CEL's. Belt squeeks at idle, but stops while driving. Belts good and tight.
Recent work:
previous owner, top end job on motor. Within last 10,000 miles.
New plugs, wires, cap and rotor.
Timing checked and is 10 degrees BTDC.
New fuel filter last week.
Coolant flush last week.
New thermostat and gasket at time of coolant flush.
New muffler and tailpipe last week.
All vacuum lines checked. No leaks.
New timing chain.
New water pump.
New IAC.
Can anybody help me with this bad mixture?
