Need to get my Vanos looked at

Hi all,

I need to get my Vanos looked at as down on power.

I’m based near Oxford.

Have tried to get in touch with Dannagh at everything M3 but no response after weeks.

Any suggestions appreciated. Can’t believe how hard it is to spend my money! :wink:

I know people who travel much further than that to ETA Motorsport in Kent.

Bunch of true petrol heads who always have given me time.

How do you know for sure that your car is down on power and how can you point the finger at the Vanos? What tests have you done?
 
Hi guys,

My engine light came on and then went off. It’s lumpy at low revs and is knowhere near as quick.

Mr Vanos has a bad review on here which put me off but maybe it was a one off?

I’ll check out these guys in Kent as I need a service also.

Thanks for your replies.

You need to hook up to diagnostics to find the actual cause.
 
OP, another excellent indy and ///M specialist much closer to you is CPC Performance Engineering in Amersham:

I'm a Huge fan of ETA the work they have done on my M3 was top notch!

I would however recommend to you Everything M3's hes had lots of great reviews and located in Banbury.

best way to get Darragh is Facebook messenger via his everything m3/// page. He has just done mine highly recommended. May need a bit of perseverance as he is absolutely stacked with work most of the time. But I wouldn’t go anywhere else.
 
Hi Michael,

That’s good to hear as I was beginning to take it personally! I can’t wait any longer so I took my car to DMWorkx and they advised that there is one fault on my Vanos on exhaust port. I’m getting my car to DMWorx who will do an insp 2 and whist it there Mr Vanos will come down and change Vanos. Will also get timing chain changed. Simon Just had new tyres so expensive month!

I got mine replaced by Mr VANOS at my home address in Leicestershire during the weekend. While he was 'at it' he also checked the valve clearance (two shims needed replacing) and, surprise-surprise!!, the timing chain was stretched thus throwing the timing out and allowing for additional rattle. Steve (Mr. VANOS) replaced the timing chain, too. I was very surprised when he actually showed me the slack. Not crazy, but a slack that shouldn't be there anyway.
The engine now runs quieter in the overrun and with no torque surges below 3k rpm.
 
Does he replace the timing chain tensioner as well as the timing chain, or does the tensioner never break on the S54 (mine did on an S38 M5). If there's not a lot of stretch, then the tensioner should take up a bit of the slack anyway.
 
You need Mark Purcell, Oxford based and a great rep. A few friends and I, all use him on our BMW's.

He's here: The Hangar Horton Road, Stanton St John, Oxford OX33 1AG. Ignore the other addresses you see online, they are old.

The valve clearances need to be done in a controlled environment of 20'C. The tolerance on them is so tight that just an ambient temp change of 10'C is enough to push them from one end of the spec to the other. Unbelievable I know, but many repeated checks both first thing in the morning (about 7'C) compared to middle of afternoon (about 19'C) can make the difference between in spec and out of spec. Confirmed with many repeated measurements over 2 days using very high quality digital vernier calipers.
 
[ref]ph001[/ref], is a car's engine. More similar to a tractor than to a nano tech robot. I was /am happy with my garage being at 17C during the process.

I’d be very surprised if any main dealers and Indy’s have temperature controlled workshops. Open plan workshops with large rollers doors, just not going to happen.

I work for a precision engineering company. We machine and measure components at 20C and the components have to be in the temp controlled room 24 hours before machining to ensure accuracy.

This just doesn’t happen with garages changing shims.
 
I don’t disagree that many garages ignore it but the BMW procedure does specifically state the ambient temp required for the measurements. Makes a bit of a mockery out of doing them otherwise.

Modern dealerships are climate controlled with quick acting fabric doors. My local sytner dealership has exactly that setup and the mechanics all work in short sleeved polo shirts.
 
...and probably even more importantly, the valve clearances should never be done same day as you drive in as it takes a long time for the engine to cool down completely. OK, maybe if you arrived at 9am, it could be done late afternoon, but usually it should be done next day after the engine has been sat overnight.
