well, just finished installing a new guibo on the front driveshaft. I noticed a mix of oil and antifreeeze all over the top of the aluminum reinforcement plate under the vehicle. My question to those: If the valley pan gasket leaks is it just coolant? Maybe my rear main seal is leaking as well. thanks in advance
Update: I finally cam around to doing the valleypan gasket. One needs to remove the intake induction hood, the air intake, fan,fan shroud, the engine cover. once i did this I started to dismantle the fuel rail and ignition boxes(one on each valve cover). once all that is removed you are left with the intake manifold. I removed the crankcase vent on the rear of the manifold so I could clean it. here is a pic once everything is off of the top of the manifold. the injector clips to pull off each ignition box was the hardest thing.
Next i proceeded to remove the intake manifold which was about 12 bolts lightly tightened. After removing the intake manifold now I had to work on removing the belts and the water pump pulley so I could reach the two bolts behind it. once the water pump was off i was able to remove the old gasket and remove the two coolant tubes from the rear manifold.
here is a pic of the valley pan: its about 14"x5" and there are about twentyfour bolts. make sure to clean the surface that the gasket is going to sit on and then reapply new gasket. I tightened the bolts in a similar sequence as bolting a cylinder head, starrt in the middle and work out.
this is really a straightforward procedure just dont follow my synopsis, get yourself a nice bentley manual and read the directions, most diyer's can do this and probably save 1500 or more at the stealership.
