Thank god I paid for an extended warranty. He told me I would have been looking at around $400.00 for the part, plus the cost of the gasket and the labor. He also said that since the late 90's and early 2000's the Camry's have had this problem and the Scions as well. He replied back it is a problem w/ Toyota and the R&D at Toyota.
Just thought I would pass this information along to those on here who have Camry engines and to be on the look out for this problem.
