Correct - bottom end in my reference refers to rod bearings. Top end refers to valve train - adjustments and all the VANOS stuffs. Main bearings don't appear to be an issue in these engines...at least not that I have heard of.

It is indeed my Imola coupe in the sig - still can't stop starring at it even after 10yrs+ with it! Slowly updating it to my liking as well...little by little. Here are a few more pictures to push you over in case you're still on the fence

Sounds like a great deal if everything checks out. Note that you'll most likely need another valve adjustments done soon (it's recommended on every inspection)

Just reached out to my local shop and they quoted me $660 labor and $120 parts on valve adjustment. Sound reasonable?
also recommended if it needed it, to replace the entire VANOS system rather than rebuild? Thoughts?
Thanks Again.

$600 ballpark sounds about right for a valve adjustment.

There are 2 sides to the VANOS system - the Pump and the camshaft sprockets. When you say replace the "entire VANOS", I'm assuming that you're saying to replace the pump (the side that separates from the engine)? Replacing the pump will only save you on the labors of replacing all the seals that's in the pump, but that's only a fraction of the VANOS' problem. By just replacing the VANOS pump, you won't address the following:
  • You won't get a tighter tolerance re-drilled disc (unless the new pump comes with one). Without the re-drilled disc, the hammering action by the exhaust hub will cause one or both of their teeth to shear off.
  • You won't address the VANOS hub bolts, that tend to shear off on the sprokets sides - this is common on the '06 and some '07
  • You won't address the axial play on the camshaft sprockets

You should ask your indie if he/she is comfortable with rebuilding your VANOS with all the Beisan Systems' S54 stuffs:
  • S54 Vanos Sealing Plate Repair Kit
  • S54 Vanos Seals Repair Kit
  • S54 Vanos Rattle Repair Kit
  • S54 Vanos Oil Pump Disk (re-drilled)
  • S54 Exhaust Upper Chain Guide (this will most like about to break at 50k miles)

What to look for in PPI

Just found an 06 Z4M in the Carolina's. Clean Carfax, 3 owners, 42K miles,valve adjustment done at 23K( spoke to the dealership that serviced the car)
What should I concentrate on with the PPI. How long would it take for the BMW dealership to have the oil analyzed? Can they check valves? Check Vanos? Whats typical and what additional service could I request that would pay for itself in the long run?
Thanks in advance for your advice.

BMW dealerships don't do oil analysis, at least, none that I know. Oil analysis requires you to collect the sample and send it off to a laboratory, which are typically not nearby. For example, it takes approx. 1 to 2 weeks to get my results from Blackstone Labs. Also, a single analysis isn't going to do you much good other than just seeing a snapshot. To be any useful, you really have to look at trends...so lots of analysis are required. If you want to read up more about interpreting oil analysis results, have a look at my thread on another forum here => https://www.zpost.com/forums/showthr...t=oil+analysis

Valve inspection/adjustments at a BMW dealership will cost you an arm and a leg. I've gotten and seen other quotes in the range of $1k - $2k just for an inspection!

Check VANOS? The only thing they can look at while the valve cover is off is to see if the exhaust hub tabs are broken - that's it. All other stuffs require the unit to be removed and at that point...you get where I'm going with this.

Here's a work in progress thread that shows what's involve with valve adjustments and VANOS rebuilt => https://www.zpost.com/forums/showthread.php?t=1709657

Thanks...really helpful.
Sounds like I'll be getting a one over with visuals, road test, all buttons pushed, etc.
Thinking they just changed the oil anyway. Did get a car fax. Looks like its been serviced all its life by BMW dealerships in FLA. Wonder if rust will be a problem? Its an 06 .
Is low mileage more of a carrot than getting a newer car? Any issues between the 3 yrs?
Thx

There are very minor differences between the 3 years. The '06 actually uses passive tire pressure monitoring (no sensors in the wheels), which is a plus in my book. It also have the older bolts (the one that tend to shear) in the VANOS cam hub. But if you're going to "bulletproof" the VANOS down the line, those bolts will get replace anyway. There are a few other minor differences that I can't recalled at the moment. But if it's a good car at a great price, I would definitely pick it up. Post some pictures and your initial thoughts when you get the car!

One other minor difference: no aux port on the '06, but it can be added - IF you can find the kit, which are rare as hen's teeth nowadays.

I'm also an EAG client. I purchased my 06 Z4M with 29,000 miles from Eric and couldn't be more pleased. Yes, I could have found a car for less money. But my car was totally sorted and had all service up to date, including a valve service, all fluids flushed and changed, New tires. Etc. I figure that alone was worth several thousand dollars. So,in the end you pay for it either way.

I was interested in more info on oil analysis and came across this video discussion. Thought it would be helpful in this thread.

Great Video...thanks for sharing.

Right in the middle of my PPI now.

Convertible top problem..
Does the top have to be removed to replace motor and pump on this 06 Z4M?
Generally speaking, is the fail point usually the motor or the pump?

Thanks for the advise...have to take this cost into consideration before final negotiation on car!

Hey Guys...

Just arrived.
Did a swap with a great dealer in NC.
My 07 Z4 with 48K miles for his 06 RED Z4M with 42K miles.
Looks perfect to me so far..Will post some pics shortly.
Question? and I knew about it before hand, top goes down fine and all front dash lights work perfect BUT it doesn't go back up without help?
Electric motor still alive, pump works great for UP, any ideas whats up with the up function?

Thx.

Not even close. Just look at estimated values between Z4 and Z4M similar years, condition, mileage. Did get almost retail credit for my trade and thereby tax was less than half of outright purchase...Very Fair.

Where do you get your z serviced in Ata?

Once you get some time behind the wheel, I’d be interested in your feedback on the difference between the old Z4 and the M.
