Got a brand new house with a brand new driveway. Something else I got that I didn't want.... a big oil leak all over that new driveway. Had valve cover gaskets replaced three times in the last year, along with an oil pan gasket. Still leaking. Now they tell me its mainly leaking from the camshaft and that the camshaft wheel is warped. Also, they tell me that my oil pressure is alot higher than normal.

Does anyone know what would cause the oil pressure to be too high? (I would have expected low oil pressure on a vehicle with 90,000 miles)

Thanks.
