ps.. .st :listen: I heard ghee and spa business also very good. Pls kontek IM and lamsing for more detail on jiont venture. Also no need starting capital.:top:

herbert.. sorry for disturbing your thread. :wink:

no problem bro. nice to have some fun after some "heavy workout".

John,

Please share with us what's the problem after installation.

I have already posted on page 18: http://www.bmwclubmalaysia.com/forums/showthread.php?t=34048&page=18 Maybe it was overshadowed.

Anyway, rough idling solved. It's due to cracked crank case vent pipe, running from valve cover to oil separator. (Part #:11151703775 , Ref: http://www.realoem.com/bmw/showparts.do?model=CD12&mospid=47447&btnr=11_1487&hg=11&fg=15 ) The crank case vent pipe was hardened already, so I think when the mechanic dismantle the vent pipe, it caused a minute crack on it.

I'm still hunting down the engine vibration problem during idling. I suspect the timing was not set properly. So, I'll continue troubleshooting tomorrow. I will feedback once I've found the root cause.

As for the Vanos grinding noise, I felt that gradually it is getting lesser and lesser. So, I guess that's what running in is.

On your engine vibration problem during idling, possible causes are:
1. engine mounting
2. MAF

bro loafer, did you have this alarm before or after you replace the seal?

It was after I changed the seals.

 

[jarance]

It was after I changed the seals.

OIC, it could be cause by sticky valve due to the harder seal. As mentioned before, there need to have a run-in period for the seal to settle in.

Do let us know if you encounter the problem again. :wink:

Yup i checked the beisan forum and quite a few people encountered that problem. Seems like it's a normal occurrence. I'll see if I have time to get the diagnostic machine plugged in some time soon.

Guys,

For those who is changing or changed the vanos seals already. Remember to ask your mech to recode or reset the vanos ! ! Or else the vanos will not work as it's supposed to be. It will not advance when your ECU give the signal and will result higher fuel consumption.

Bro - i think you are right. My FC really drop bro. I used to get about 800km on a full tank. Post seal change I get around 680km!!! I must get this reset asap. This is done via diagnostic? Thanks bro for alluding us to this!

I had spoken to my mech today and even GT 1 cannot reset the vanos systems for E39. I'll try and find out more info regarding this from him.

 

[bmw7833]

Any feedback from those changed the seal for increasing FC?

 

[Herbert]

After I replaced my double vanos seals, low end torque improved and acceleration is smooth without any hesitation. However my FC did not improve at all. I was getting 12.7L/100km city driving and highway/outstation 11 L/100km. Checked with Beisan and was told most likely pre-cat O2 has degraded. After replacing O2 sensors, FC now is 11.8 L/100km (stop/start aggressive city driving) and 9L/100km highway/outstation.

 

[loafer]

Error code 212 "mechanical jam" for Vanos is still present today when I plugged in the diagnostic computer.

I'm going to swap out the vanos with a spare from the workshop. Not sure if it's safe to remove the seals again after it's seated in the piston but if that's not possible I probably would just swap the pistons around.

Will have to wait a while before I can do this as I'm waiting for some parts to change my leaking oil filter housing. Also hopefully herbert will be able to order the rattle kit for me so I'll do it all at a go.

Your purchase of qty 1 rattle kit and payment status posted under 4th Group purchase. Thanks.

Hi Jarance,

Gotten this info from my mech ! ! I'll try to get a print-out of a non working vanos read out from him tomorrow. Then I'll post it out.... After changing the vanos seals, it's a must to check the vanos from the system.

I had spoken to my mech today and even GT 1 cannot reset the vanos systems for E39. I'll try and find out more info regarding this from him.

Any updates yet bro? We're keen to know about this before & after vanos read outs. IF GT1 kenot reset the vanos, what's the oth alternative? TQ.

Hi Guys,
Was in Auto Bavaria Glenmarie for the BMW Innovation Day so decided to drop in to my mech place in Ara Damansara to try and get further info regarding the vanos issue for E39. The guy was busy with the E46 328i ZF gearbox overhaul so I try to make it fast for him ! According to him, he can try and reset/recode the vanos system but no guarantee on it. However, if it's works then pay money lor.... If it don't, then you pay nothing ! ! hahaha....

 

[loafer]

I'm curious to know what this "resetting" of the vanos actually is. Can anyone be kind enough to explain? I'm assuming this isn't available on the E36?

 

[fandango]

Hi

I replaced my single vanos seal about a month ago. The results today are:

1. Noticeably improved throttle response. No more lag or hesitation upon sudden WOT.
2. More "throaty" engine note
3. Overall better drive; excellent bang for the buck.

Fuel consumption stayed the same, but I'm driving the car harder .

bro,

Would you please have the honor and post this question in the vanos forum http://www.bimmerboard.com/forums/vanos/.

I had my VANOS seals changed today on the new engine, took the opportunity to change now before trying out the engine beforehand coz the engine is already on the floor, so workmanship tay payah kira la. Also made sure the alignment of the camshafts and the pulley was proper. I also saw those fellas changing the seal on max's E38 today. Got confidence on all your respective feedback, hope it feels super for me too.

Yup - finally had time to get my vanos seal replaced over the weekend in addition to the valve cover gasket and the valve cover screw rubber o-rings
Felt a noticeable difference in low end torque and overall responsiveness during acceleration. Looking forward to properly run in the seals to see what the fulll effect will be but based on Kevsters feedback I'm excited
Will have to keep an eye on the fuel consumption - I am unsure whether the vanos was reset by my mechanic

Guys, I read this in the e46fanatics forum with explanations by Mr. Rajaie himself.

The BMW TIS (software repair manual) and in mimic the Bentley manual do call for resetting the engine timing when replacing the vanos. But there really is no reason to do so. I don't know a good reason why this is called for. Removing and replacing the vanos on these engines (M52TU, M54, M56) does not disturb the engine timing. Other engines like the M52 do disturb and need to reconfigure the timing when replacing the vanos.
The engine timing is set in the sprokets and chains and that is not disturbed. The splined shafts (helical gear cups) can even be theoretically removed and replaced without disturbing the timing. The splined shafts are keyed. Many owners, and I expect mechanics, have replaced the vanos without resetting the timing. Many have performed the vanos seals repair without resetting the timing.
It's also precarious to reset the timing, even with the special tools. I know two owners that have attempted to reset the timing (for non vanos issues) and have failed and are receiving fault codes. They used the special tools. I have spoken with one mechanic who has had trouble with this.

I understand that since the TIS calls for resetting the timing that owners will be concerned that it's necessary. I need to find a way to speak with some BMW dealership mechanics to see if they have an explanation for this. Maybe BMW felt that while so many components were removed that it's a good opportunity to reset the timing.

There is no reason to disturb and reset the timing when performing the vanos seals repair kit installation.
