SOURCE: bmw n42 oil pump

the m42 oil pump is located inside the timing chain cover and is an integral part of the casing so it is neccessary to remove the water pump + viscous fan etc to expose the pump front cover then remove 4 machine screws to examine the pump rotors underneath.

Bmw 318i oil leak


make sure that the filler cap seal is in place and not gone hard over time also has the rocker cover been off at some stage if it has check that the gasket has not moved the other thing to look out for is that the PCV (breather )valve is in good working order if it is damaged the sump compression will rise and push oil out

I drive 3181 N42 02 Reg. I'v been told the car has oil leak, jus yesterday whilst driving I could smell something like burning metal and a particular noise I don't know where it is coming from. Please...


Let an auto tech look at it because one way or the other it's going to end up on some tech's hands. Burning oil smell must be from the valve cover leak and dripping on top of the hot exhaust manifold burning it. The only time I smelled burning metal odor was from a smelting plant. It had an acidic smell that going to put you in tears.

Check engine light 2003 BMW 325i


both codes are for lean mixture ... bank one and bank two .....that usually means a vacuum leak in the air intake system ... there is a Y shapped boot off the throttle body that fails frequently .. look for a hole or tear or general deterioration ... there is a second boot after the MAF (mass air flow) sensor, that is another possibility ... any off the vacuum hoses you can see under the fancy cover plate could be leaking .. there is a "crank case breather diaphram" that can do the same ... you can test that by removing the oil filler cap slowly (running) ..there should be a sllight vacuum release ... if its a big vacuum whoosh and maybe engine stumbling then suspect the crank case breather diaphram ... finally you could have a bad MAF sensor but more likely the vacuum leak ... running with a lean mixture can eventually damage valves and valve seats ... i use a small rubber hose to my ear to find vacuum leaks (stethoscope) ...

possible valve cover leaking,at least this is more likely the cause, they make a die that you can use too help determine where it is leaking but some dies require ablack light too see the die,
