I just notice your N46 has EGR. Remove the thing la.. very kacau and require regular costly maintenance.

N42 la bro...if its that copper thingy next to the exhaust manifold , its not EGR but a stop valve for the air pump which is used during warm up I think....local models do not have it...

Wahhhh!. For long time my leaking prob ok already. Last service change valve cover gasket. Also done the vacuum pump seals. Today no stain on the garage. And very lucky when took a look on my engine last service, it's very clean and no sign of sludge. The car was done 105000 mileage. Thanks to the previous owner who took a good care of the car. Will service on time and take a good care too. If take a good care and well maintained your n42 engine i think it doesn't much a problem. Also will monitor how long does all the seals will last.

yeap I do believe if the n42 is taken care of it would serve well into its twilight years, as with many cars these age obviously those seals wont lasts...what more they build the n42 to be like that compared to the m50s...sigh but I digress...

Viva la N42!
