My truck has about 415,000 miles, about 300,000 miles on the new engine (2003) after the factory hydrolock took it.
I went outside and turned it over and it went half a cycle and stopped. I checked the voltage on the battery, its 12.8v idle, so I know its not dead. The truck refuses to turn over and I think its got water leaking into the cylinders. I'm going to try to pull the plugs out this afternoon and see if I can confirm my worst fears
---------------------------------------------
I tore it down to the lower intake manifold. Turns out my Bank 2 IMRCs arent connected for some reason. I'm not sure if its a vac line or what at this point, but they're just flopping around in there. I hope thats the cause of the mystery rattle and CEL!
I need to run to VatoZone tomorrow and get the fuel rail disconnects and then the lower intake manifold is coming out.
I took off one of the valve covers to see how well this 300,000 mile engine is doing with oil. It is C-L-E-A-N!! No sludge or anything! I'm happy about that.
Also found my 2-year old 2-row radiator is leaking...so that has to get replaced as well. This sucks because I was hoping to get my tires on this weekend, looks like I'm set back another 2 weeks since I have to drop ~$200 on the engine. The injectors are covered in gumminess. Is it safe to put injectors in an ultrasonic cleaner bath? Hopefully this eliminates some issues and makes it run better!
Does anyone know the Ford Part Number to the lower intake manifold gasket? There is a whole slew on RockAuto and I'm not sure which to use
