Just re-read this thread again as a reference - getting ready to change my valve cover gaskets and upper timing chain cover gaskets soon...

Wilson - is your car up and running now?

Mein Auto: 02 745i
I have a 2002 745i and really enjoyed this write up! I am a former BMW tech about 10 years ago, and really liked this write up. I plan on doing most of the work on my 7 myself aside from the electronic programing since I dont have the factory computer at home, lol. Good job!

Well it would have been ready to go. But I discovered the source of my misfires was bent exhaust valves on cylinder 1&2.

I did this manually before I had my timing kit.

After finally figuring this out.... I pulled the head and ordered new valves and sent to the machine shop.

I should will be getting it back today. Over all it was about a $350 mistake. (not including time, but this project is all about patience and perseverance and a great education....)

Head gasket, Bolts, and valves were about $250 plus another $100 at the machine shop.

I'll update here once I get it back together, but I've been taking pictures.

So basically I know how to change an head gasket on a 745 now and it isn't very fun!

fyi- I considered pulling both heads and doing a complete valve job, but the heads were very clean and the amount of money I would need to invest (time and money) wasn't practical for any percieved benefit..

Cylinder Head Removal

To Remove a Cylinder head you better be familiar with your engine. And its every bit as difficult to remove as BMW likes to do with its other stuff.

1. Remove the Valve Covers and all the stuff in the front.
2. Exhaust Manifold.
a. To Remove the Exhaust manifold you have to drop the front axle support. Why? Its the only way to get the clearance you need to get at the exhaust.
b. This means you need to lift the engine with a engine puller to support it.

See Keifers DIY on dropping the front axle support.

Its not that hard and I did the entire job by myself. The axle is light and can be lifted/pressed on and off. But a jack of a friend would definitely make it easier.

3 Once the exhaust if off you have to bolt the axle back on.
4 Lower the engine back onto the axle support so the engine puller can be removed.
5. Remove the EGR valve
6. Drain the antifreeze from the block from the drain bolt underneath the exhaust manifold
7 Unbolt the head bolts. Pitch them or save for something else but do not reuse.
8. Lift of the head.
9. If antifreeze spills out you will need to flush out your oil system.

Pics of my Bent Valves

Took the Head and the new valves to a machine shop and had them refitted for $40. The best value of the whole project.

The Intermediate Levers are on the Intake Valve Side only.

They are used by the Eccentric shaft/actuator to set adjust your inlet camshaft/valves.

Once your ready to go its just a matter of doing everything in reverse order.

Getting the new head gasket on and easy. Just put torque down your headbolts in the correct order. See Pic.

Understanding BMW Timing.

I made this document based on what I learned and the TIS and from my Friend Keith and some good ole Reverse Engineering backed up by verifying it works.

If you can understand this document you can time a BMW.

So hows it running after this huge project? Your 7 should be running as good as the day it came off the line. Good job on the diy.

For reference, making some long dowels to thread in place of the middle two bolts of the front axle support makes raising / lowering it much, much easier.

When trying to understand the timing, read Wilson's document thoroughly, and keep in mind that the intake cam lobes actually contact the intermediate levers at a 45 degree angle (southeast on bank 1 / passenger's side, southwest on bank 2 / driver's side), and those intermediate levers in turn contact the rockers. This is important because the intake cams will look like they are 90 degrees off from each other...until you take the contact positions of the intermediate levers with the intake cams into account, then it should all make sense.

Yeah... Going way back. When I replaced my sliderails the exhaust cam on the pass side slipped more than I realized. This was before I understood the timing. I rotated the engine 1x bendn the valves . I then timed the engine not knowing I had already bent the valves.

Post Parts List

I was gonna change my valve cover gaskets and stumbled on this thread. I have oil in the plugs and idling is not so great. Also got the tic tic noise. Great information here! Thanks to Wilson for taking time to document all this and thanks to other contributors too!


A question: What is the part number of the bolts in the valve cover? The ones Wilson recommended to replace?

Here's the list of the parts I compiled from this and other threads. If you guys have some suggestions to add, change or subtract from the list they are more than welcome.

Edit: REALOEM.com links are not working in the pdf, sorry

I'm getting ready to replace the coolant pipe with the All German Auto unit and it mentions removing the intake cam adjusters. I've read in another thread people questioning why they sell new gaskets for those, which suggests they don't need to be removed. Also, the pictures in this thread make it look like you can remove the intake manifold without removing the adjusters.

Do the adjusters need to be removed to pull the intake manifold and valley pan to access the long pipe? If so, can they just be bolted back in, or do they require a timing procedure/special tools?

Thanks

No you do not need to mess with the adjusters. Just pull the intake manifold . The adjusters and timing was to pull the head to fix a bent valve .

Ok, I got the engine apart (harness, injectors, intake mani., valley pan, etc.) and yes the adjuster didn't need to be touched. Thanks! But now, once everything was apart, I decided that the valve cover gaskets should be done as well, so the ajusters do need to come out.

I think we might be using different definitions for adjusters as the ones I was referring to are underneath the valve cover. I hope your project went well.
