Opinion on N52K valve cover replacement vs. PCV valve replacement.
Hi All, I was after opinions on replacing the valve cover vs the PCV cover on the N52K engine. I have read a few forum posts stating no problems with the cover replacement, but every video on YouTube has a follow up comment which seems to imply it didn't work and that they replaced the whole valve.
As it stands, the eccentric shaft sensor has a leak and the PCV is blown (hand tested with a vacuum pump), but the valve cover itself has no leaks from the gasket, valvetronic gasket or spark plug tube gaskets. No history of if/when the cover was last changed. Is it worth just replacing the whole thing, or shall I just replace the eccentric shaft gasket and the PCV valve? Does anyone have positive experience with the value? Thanks! |
