I've been using oil and coolant for a while now, and had not found the cause until recently. I believe have a leaking lower intake gasket, which I will replace tonight. I can only hope that nothing is cracked and that the head or head gasket is not involved.

The oil has not shown any signs of emulsified oil/water and tests fine, but the cooling system is another story. At this point there is a fairly large amount of oil sludge in the radiator. I'm not running hot, as I can monitor the temperature readout using my scanner while driving. The only time I notice any issue with temperature is when running on long hills, or when sitting in traffic, which will lead to a 5-10 deg F rise in the temperature readout.

I'd like to flush the coiling system out with something that will remove the oil sludge. I've read about using soap (i.e. automatic dishwasher detergent) and I've considered "Lestoil" which is household degreaser that I've used to clean parts at times. Does anyone have any additonal suggestions?

Also, I had to abort my first try to replace the intake gaskets last Saturday night because one of the bolts would not turn. After I rounded off the head with my 7/16" six point socket (why such a small head!!), and knowing that I did not have a replacement, I decided to wait until I had a few replacment bolts available to complete the job. It's the first "low" short bolt next to the #1 cylinder, very hard to access with a cutoff wheel or anything like that. I also can't get in there with a hammer and punch to turn the bolt. I'm planning to use a drill or Fordham tool to remove the head, then remove the manifold with the shaft of the bolt still in place. Any better suggestions?
