    There isn't coolant in the oil. The heads are getting done. It's looking like the previous owner didn't maintain this truck at all. I'll clean the crank case breather when it gets home. I'm sure it hasn't been cleaned in 10 years

    The egr cooler is clear. Going to pull the heads to get the freeze plugs replaced and gone through. Guess the rings are getting bad. That will be a battle for another day. I'll have the crank breather checked as well

    2004 E7 427

    I have a 2004 e7 egr engine. The egr cooler is totally plugged. It has oil leaking from the exhaust manifold bolts, the freeze plugs are leaking, and blow by is coming from the front main seal. I'm having the cooler cleaned. Would that cooler being plugged cause back pressure in the engine? Is there a vent system that maybe plugged that is causing the blow by comming from the front seal? The engine has no power. Mack sent an oil sample out, i don't see any signs of coolant/ oil mixing. Is this a issue of to much pressure inside the block? So far its been to 3 different shops. 2 said oh is bad and we aren't opening a can of worms. Of coarse after they charged me $1000 and $1400 for mickey mouse fixes. Now Mack has had it for 2 weeks, said its throwing an egr valve code, they said it is working, and 2 injector codes. They don't want to work on it either. They all say its bad, but wont tell me why. They all want 10s of thousands of dollars to fix it. What on earth is going on with this thing?

    Heater fan wiring harness

    Did put a new resistor in. The old one was fried
  5. Been trying to get the heater fan to work on something other than high. Thought it was the switch, no biggie. Problem is the connector is melted in the center. Mack recommended changing the wiring harness. Problem is, it goes into the dash and goes around some gizmo and I can't find where it goes from there. How do I change this thing out without tearing the entire truck apart? It's a 2004 Mack CX

    R model door locks

    I didn't know the lock had to come out first. I've driven tons of R models. Can't remember ever seeing the door apart. The window split right down the center and half fell into the door. It jammed in, so I had to get it apart with the window up. We did with out breaking any of the glass pieces. It broke the inside of the lock. No biggie, it had to be changed anyway. I don't have a key that opens it. I'm going to put the new glass in tomorrow. Figure I'll change the lock while the door is already apart.

    R model door locks

    The lock tumblers themselves.
  9. How do I change the door locks on my R model? I'll have the door apart to replace the window. Figure I may as well replace them while I'm at it. Thanks
