Looking for help with engine timing, M62TU

[MrFixIt]

Please recommend a reputable BMW tech/Indi--Kansas City area.

I'm looking for a BMW tech/Indi in the Kansas City area to help me do the timing on my 2003 X5 4.4 M62 TU engine at my house/garage. I have the timing tool kit, but would like to try a different one if you have it. I'm willing to pay a fair price for your time. I will have everything all ready to start the timing when you arrive. You show up and help me go through the steps. You are done when the timing is done. I can put the rest back together/close it up. The worse part about this timing design is that we don't know if it's done right until everything is put back on...what a pain.

Only redoing timing on Bank 1 (P0011 code, Bank 1 A over-advanced). I was advised that it is not necessary to open up and redo the timing on Bank 2. Is it better to redo both Bank 1 and 2 again?

I'm throwing in the towel. Please help...I'm tapping out

Part 1: DIY, Replaced all timing chain guides, rebuilt VANOS with Beisan kit, etc. Put everything back together and engine started right up. Got a P0021 code "Bank 2 A over advanced". Rough idle and reduced power at low rpm. Drove 25 miles.

Part 2: Tore it down and redid the timing, both bank 1 and2. Started right up and ran ok for few minutes before rough idling started. Code P0011 this time, "Bank 1 A over advanced". Same symptoms, rough idle at low rpm; smooth at above 2000 rpm.

Part 3 (today): Opened up only Bank 1 and redid timing today. Started right up and ran smooth for only a few minutes before it went into rough idle at low rpm. P0011 code showed again, Bank 1 A over advanced. Runs great at above 2000 rpm, but very rough idle/below 1200 rpm.

This was a huge job, and overall everything went quite smooth; however, I am stuck on timing like a ground hog day.

Thank you.

What is the milage on your car and did you service your timing chain as preventive or were there symptoms? I am thinking to service my timing chain while doing the valve cover, valley pan and cooling hoses and having 2nd thought about removing the front of the engine for the chain is PITA. I don't have any symptoms on the timing chain yet and currently at around 92k mile.

My X has 135,xxx miles on it now. Did the chain guides as preventive maintenance. Had these symptoms a couple of months ago:

Extremely loud grinding/crunching sound on two start-ups; they lasted about 3-5 seconds, but seemed like an eternity. Now I know it was the chain grinding on the plastic chain guide that had broken off. One of the guides was missing a 1" chuck of the plastic, and the rest were extremely brittle, especially around the thin edges.

You don't have to remove the oil pan or drain the power steering fluid. The lower bolts on the lower cover are outside the oil pan on the X5. I found this out after removing the oil pan cover ...it was great to see inside the engine though.

The crankshaft bolt "Jesus Bolt" was uneventful. Came right off. Just use 3/4" impact socket and 3/4 breaker bar, along with a 4-foot steel pipe (from Home Depot). Spray it with PB Blast a day prior. Be sure to use the crank holding tool--not the fly wheel pin.
Here is a good consolidation of the job: http://www.xoutpost.com/bmw-sav-foru...ides-4-4i.html

I went very slow and learned a lot about the entire process and how the engine parts all come together. I read and study all the write-ups to the point of muscle memory before starting the work. Get all parts and tools before you start the work.

I change the oil every 5,000 miles or so; original owner since it was new. I am convinced that the chain guides should be replaced at or soon after 100K--they are just high impact plastic. M62 engine.

I'm redoing the timing again tomorrow with this new set of timing tool:
BMW Master Cam Tools DIY

Purchased two days ago. Just arrived today. They seem more precise than the clunky two-section blocks I was using. Will report back...

Success! Timing is a GO. Engine idles very smooth and no codes. Can't wait to test drive it tomorrow. Still have to put the skid plate on.

Redid timing just on bank 1 with this timing tool:
BMW Master Cam Tools DIY

Everything went extremely smooth and the tool is so much easier to use than the clunky OEM two-connecting blocks style. Everything is definitely more precise, extremely user-friendly, and the bright red anodized color is nice, too. Wife said they look like pieces of art work.

I highly recommend this GAS timing tool (not associated with them) over the OEM style. Wished that I'd known about GAS before wasting all the time and energy with the timings.

Thanks for all the input.
