My n42 gets through a fair amount of oil and have been trying to pin-point the problem for a while.
The cam cover gasket has been done, which doesn't seem to have stopped oil loss but MPG has increased around 5!
I took the pollen filter etc off today to take a look at the vacuum pump as I get puffs of White smoke from the engine side of the bay. I also get the burning smell shortly after starting from cold.
The pump looked ok but think I will take it off next weekend for a clean up.
I cleaned oil residue off the engine also and went for a run and noticed fresh oil here:
Any thoughts/suggestions much appreciated!
Thanks in advance!
