On my MRS3 is an oil leakage all over all cylinders. I suppose that it´s from the camshaft studs coming up. I´ve cleaned it completely with brake cleaner and blow it away, was really clean and dry. 2 weeks later, i´ve removed the engine cover and found the leakage again around all studs. How can it be fixed? Supposedly they didn´t use sealer or Loctite when fiiting the bolts. Did anyone fix it permanently? I´m not fancy to remove the valve cover, the camshafts will be relocating and it´s the same expense as to replace the timing belt, even more….How to get out the oil of the threads to make the sealer work?
