talking about the facelifted car. The 318i provides much better fuel consumption and much better performance coz it is equipped with BMW VALVETRONIC system which is much better than the 316i. In case of the prefacelifted models .. you could not tell much of difference but the new 318i engine won prizes it is much more powerful with the 316i To set the timing you should turn the No.1 piston to TDC, then turn the cam to where both valves on No.1 are close. The timing mark on the sproket should now be in line with the mark on the cilinder head. With No. 1 still on TDC fit the chain. After fitting turn the engin a few times by hand to make sure there's not a valve pushing against a E36 Problems troubleshooting relay / DME. Fuel pump not getting power, worked my way back, tested fuel pump relay, main relay, ECM/DME wiring, DME PIN's where I could. - PIN 30 to PIN 85 (ignition off) = 12v.

Hi, I have recently purchased a BMW 316i (1999) from octions, but seller was BMW dealer. The car was declared as no major problems. Just when I am about to declare proud owner of BMW, I have found some traces of oil in the middle of right side of the engine. :rofl There was no white smoke and coolant The Idle Control Valve is effectively an electromechanical throttle body that meters air below 20% throttle. The Crankcase Vent (CCV) allows oil mist to condense and drain back into the sump via the oil dipstick. The DME measures intake air temperature using this sensor. Replacement is entirely optional, but convenient while the throttle bodies The BMW N46 was a new-generation engine, but it did suffer from some common problems. These included high oil consumption, vibration caused by the VANOS variable valve timing system, leaking valve stem seals, and rattling noises caused by worn timing chain tensioner and guides. BMW used the N46 engine in the BMW 316i, 316ti, 118i, 318i, 318ci Into this arena came the E36 Compact – a 316i with 102 bhp and a 318ti with 140 bhp. Using the front half of the E36 sedan, a whole new rear end was designed, and with it came what appeared to bmw e36 icv. The last major maintenance items which are frequently overlooked, are the two valves underneath the intake manifold. This would be the ICV and the PCV. These two valves are extremely important for the proper functioning of your vehicle and need to be replaced around the 100-110,000 mile mark. 7UaGb.
