N62 Timing Chain Cover Removal

I'm working on replacing the gasket for the left timing chain cover on my N62.

I've got all the bolts out except for the one behind the alternator bracket.

I watched this Zeiten LLC video on how he did it on a 7-series, and I'm guessing that I'll need to do it the same.



However, if I have to pivot the alternator bracket, won't that mess with the infamous oil gasket that's in that bracket? From what I have heard, replacing that thing can take as long as these timing covers!

Also let me know if there's a way to deal with the hard coolant pipes directly in front of the bolts for the timing chain cover. I managed to get them out but it was a lot harder than in the Zeiten video.

Thanks!

yep... thats a mother fk'er of a job..

If that was a m62, and not a n62 Id say just do the timing.. your already there (* i dont believe the n62, suffered the same failing timing guides as the M62)

wait till you meet the Jesus bolt,


Oh lol your only doing the upper's so you dont get to meet the jesus bolt this time...

best way to meet and greet a 62 series motor is to just take her apart

they only give you like 19 hours book time to do a timing job...

Its pretty easy all of it.. its just time consuming because if its the first time coming apart, everything is dirty and stuck fast... a lot of things want to break, you end up having to order more and more as you go on....

My first time was brutal, i remember very specifically working for free that job.(*i blew over 15 hours) it was a learning experience at the owners expense: (*particular situation was ruff, it was neglected )

my 2nd time doing a timing job i did much better, the 3rd i let someone else deal with it...

yeah so your doing the left upper?

alternator is on the right boss... are you thinking of the ac compressor? Its easiest to look at it as bank1 and bank 2

bank 1 is passenger side
bank 2 is drivers side,

(*except right hand driver versions)

Iím working on Bank 2, replacing the gasket for the upper cover (not messing with the internals).

Maybe itís just me but Iím confused. Are you trying to replace the left, right, or lower timing covers? Itís not too complicated of a job. You donít need to remove alternator bracket bolts. Something doesnít add up.

I'm sure that it's me, the new guy, that's causing the confusion. I'm trying to remove what the manual calls the "left top gear case cover" as shown in the attached photo.

The bolt in the bottom right corner does not appear to be accessible.

Looks like the left with the vacuum pump. If you have the vacuum pump off is there just a coolant hose in the way?

I think that some of the confusion here is that the BMW manual refers to "left" and "right" from the perspective of sitting in the car, not working on the engine. For example, if you browse to the page on newtis.info for the right valve cover, they show the valve cover with the oil cap on it.

If I'm looking at the engine, I'm inquiring about the "right" cover near the alternator, not the left one that's behind the vacuum pump.

On the 750 N62, I loosen the lower and removed the upper alternator bolt, then swing it down a bit. Doing this, exposes the last lower torx bolt to be removed. You'll need a 1/4in torx socket.

Thanks for the advice. I did as you instructed, and discovered that the obstruction is not the alternator bracket. Itís some other sort of bracket that is sort of wing shaped and goes diagonally down and next to the belt tensioner. Iím attaching one picture of it next to the tensioner, and another picture looking down on it from above the timing chain cover.

Anyone know what that thing is, or how to remove it? Thanks!Click image for larger version

Looks like I have something extra that you donít. Maybe related to an option that you donít have? Itís blocking the bottom of the cover. Hereís another picture. Click image for larger version

I know that the black wire loom is for the alternator wire, and thatís not whatís in the way. Iím referring to the grey metal bracket with the square-ish holes cast into it. The alternator wire is routed on top of it.

Just the parts for the cover itself (gasket and VANOS solenoid o-rings). I also have everything for the valve cover gasket replacement.
