Major engine malfunctions

So this is somewhat a continuance of my low oil pressure issue thread back in April. After pulling the valve cover and find pieces of my old serpentine belt i pulled the engine and stripped it down and found #1 connecting rod bearing spun causing both damage to rod and crank. So sourced a ebay crank from a 335i and 2 connecting rods #2 also was showing signs of damage. So rebuilt the engine. Now for the nightmare to really begin. Engine is hard starting as in very long crank cycles and will slowly start firing to life once fires it will run as it should untill it starts warming up then i have to push on the accelerator pedal to keep it going, if let idling it will just slowly peter out. Now for what i have checked,

Faults using rheingold ista d have a couple
002A9A INLET CAMSHAFT , SYNCHRONIZATION, i have checked timing,camshaft and ledges, swapped solenoid and cam sensors, codes stays the same
002DED DME POWER MANAGEMENT , Self induced
S0098 NO COMMUNICATION POSSIBLE WITH; ELECTRONIC FUEL PUMP CONTROL MODULE. i have check both the low and high pressure fuel pump psi low was 6020 Hpa "87 psi " and high would climb to 150,000 Hpa :2175 psi" while cranking, so would appear the fuel system is capable of delivering the required fuel psi to idle at a minimum. I have also triple checked the timing , tried moving the fault , checked power and ground at connector all ok,. Missing something just cant think of what

timing, you have a timing issue..

how did you set the trigger wheel? *did you pulse/sound time it?

your problem is timing thats all..

the other 2 codes are probably phantom results

that 2a9a is a fancy way of the car saying its having difficulty figuring out where the top end is and its not pointing to a vanos sync error (*which is normally a sensor issue) i beleve thats the 2a99/ 2a98

judging by what you describe the engine is really retard, which is why you can keep it running after it warms up, and why the long crank

I have the proper tools to set the trigger wheel for the camshaft. Starting to question if the vanos gear on the intake side has somehow failed, noticed that after setting the timing and then rotating the engine to check the time the intake vanos gear will start to rotate with the chain but the cam stays stationary for a couple of degrees. I have been assuming it's normal but now thinking there's something screwy going on with it. Can anyone else confirm this as normal for the vanos gear?

So finally got her running correctly. Can't really pinpoint exactly was the issue since I did 2 things , 1st was installed a new / used vanos gear on the intake cam shaft and 2nd was to take both exhaust and intake vanos gears off and start from scratch during the timing procedure, thought was that by trying to set the timing on just the intake side which is also the none tensioner side that there was some slack in the chain when torquing down the bolt. I did notice that the intake vanos gear did not rotate separately from the cam a couple degrees like before but didn't really focus on this since they are made to do just that. Hence Variable Valve Timming.

yeah, the way Bentley describes the timing procedure isnt really complete

there are a few little things that you have to do that are not really in the book..

Ive have to retime a motor or 2, the way the pulse trigger wheel works and stuff is kindda rocket science'y

there is a guy over in the e39 sub, jimlev who is really really good at timing these v8's i think he is also on bimmerforms, Ive consulted him a few times for things like this,

that 2a9a went away right? glad you figured it out.. Im not looking foward to working on the timeing on this N series motor...(even though your not a v8) I find that the v8 timing is a little more complicated then the i6's


you had to kindda preload the chain a little before you locked down the wheel right?

Yep 002A9A has not come back. I have the Bentley manual but also have the latest version of ISTA-D which has the factory repair manuals in it but typically I use BMW TIS which is the same as what's in ISTA. Both are complete in the task. I used the original tensioner to preload the chain by just turning it out almost all the way and then turning it in by hand a couple turns. Overall the whole process itself is not difficult. And you do all this BEFORE locking down the BS onetime use bolt.
