SOURCE: 318 timing chain setting m42 engine with out bmw tools

Remove the cam cover, remove the spark plugs, turn the engine to number 1 TDC, put a pencil in spark plug hole number one and twist the crank back and forth and make doubly sure you are at TDC. Now loosen the four bolts at the front of each cam sprocket, check TDC again with the pencil and rocking the crank, now take the pencil and lay it across the flats at the back of each cam. Twist the cams very carefully so that the pencil sits flat on each cam square. Snug up the sprocket bolts and use the pencil to check TDC again! Now check the cams again. Repeat the procedure until you have the cams flat and the engine at TDC.

SOURCE: Does a 1993 BMW 318i have a timing belt or a timing chain?

Hi some of them have a belt but yours being the M43 engine is a chain, the only thing to listen for with them is chain slap or an rattling around the chain area, a bit of research on the M43 engine also shows that the chain should be changed after 100000 miles as they become weak, Just joined here and found this unsolved i know its a bit late but hope the extra info helps

SOURCE: Cam position sensor error.

It's not enough only rebuild yours engine !!!
After new camshaft position sensor instalation and timing perfectly alignment you must scan the engine control computer and erase these error, actually all errors stocked in memory. The best scantool is VAS device used by VW-Audi dealers, VAG-COM by RossTech (cable + software 704.014, 805.01, ... on CD), or also Bosch KTS 540, 570, 670, ...
RESET = erase errors from the engine control computer memory !
Yours engine control computer don't understand if you only replace damaged sensors with new others! Errors still remains in memory affect engine runing!
Best regards!

Bmw m42 engine to fit a camshaft sprocket to a camshaft


The M42 and M46 engines have the twin vanos pulleys and require locking tools to lock the crank and cam shafts inot the correct position. There are no timing marks on these as they are floating pulleys- ie they have no key locating the pulley in a specific position on the cam. Unless you make accurate marks during stripping there is very little chance you will be able to get the cam timing right on this engine without the cam locking tool kit.

I need a diagram of timing chain replacement Thank You


During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

Need to know how to set the timing


Cylinder #1 set at TDC, compression stroke. Cam marks level with head, aligned with mark on cover, or if unclear where to mark the cam: SET Cam at point where intake valve has just closed and both valves are shut on cyl. #1, cam gear marks should start to appear more clearly to technician, along with corresponding alignment points. This is ballpark. Remember, on clockwise rotation, after cylinder #1 intake valve(s) are shut, the cam will continue to rotate 90 degrees and come to rest at a position in which both exhaust and intake valves are at their maximum lash point. (the most play) Hopefully if you get this close, you will decipher the marks that exist on your Bavarian machine.
