Re: Oil in coolant...
Thanks Chipset. I'll print your reply and ask him all these questions. They said they ordered the parts using the VIN. At the time the heads were replaced, the timing cover wasn't removed. He told me from the begging that the head bolts needed to be replaced and they were. They said they put high pressure air on each cylinder and didn't get any air entering the cooling system.
As for blowing the heads gaskets....I had coolant gushing our of the very front of the right gasket. When replacing the gaskets both heads proved to be warped. When looking up the engine on line and reading about all the changes to it over the years it was mentioned on one site that about 25% of all heads or gaskets are blown or cracked. Of course, you never know with the internet.
