SOURCE: 1987 bmw 325 idles rough

I had a similar problem on a 318IS.
The rough idling was accompanied by an occasional whistling noise from the general engine area (caused by air leaks through the front and rear crankshaft oil seals).

The problem was caused by a faulty crankcase ventilation valve (Costs about $100).
The vent valve is easy to replace - (2 screws) - check the vacuum hose that connects this valve back to the tappet cover air vent nipple - it goes soggy and disintegrates.- replace with suitable oil resistant vacuum hose.
While on the job, clean the throttle body / butterfly valve internally with a soft toothbrush dipped in petrol. This cleans off sooty deposits - makes engine idle rpm more consistant.

I have a bmw e30 325i it cranks but will not start so what can I do to fix it?


Fuel Pump - can you here the pump (usually under the right hand back seat) running with ignition on?
Fuel Delivery (injectors) - squirt some fuel (just a cap full) into the manifold.
Spark - pull a lead off a spark plug and use a spare spark plug resting on the exhaust manifold.
Crank sensor - Injectors won't inject fuel if the ECU thinks the engine isn't turning. Crank sensor is at the front right lower side and as it gets older, the wire gets brittle and breaks most of the time where it meets the hard end. The connector is under the throttle body and should read 500-600 ohms.

Hi, You need to check for fuel and spark. Spray starting fluid into the air filter then try to start it. If the car trys to start then you have a fuel delivery problem, could be fuel pump or filter maybe even wiring for the fuel pump like the relay. If after spraying starter fulid it won't start then you need to check for spark, pull a spark plug wire and place a spark plug in it, ground the side of the spark plug to the metal part of the engine, have someone help, try to start the motor and look for spark at the end of the spark plug, if no spark then you need to check the electrical system and the timing belt. log into the local libary web site and find the auto reference guides for you r car that may help also, Good luck.

Need location of fuel pump relay


You are going to have to remove the fuel pump and disconnect the wire harness. Check for voltage at the plug. Not sure of the excact location.
