i have a 2005 pt cruiser with over 100000, miles...it has been running fine, i left it in the garage for 2 weeks when i went on vacation and when i came back i used the car and i saw the oil was leaking. when i took it in, my mechanic said that the front seal was broken, he fixed it, but two days later it was leaking again, i took it back and he said the oil pressure was high but he doesnt know why, its been at his shop for over two weeks and he still can find the problem, anyone have any suggestions why the oil pressure is high
