    Post 63k miles - VANOS Exhaust Hub FAIL

    Brought my 63k mile E46 M3 in yesterday to have one of my 3 BMW Master Level techs do a 'premium' Inspection II + VANOS bolts. The car has been running great in this cold weather - I was excited to get it back Monday in 'like new' condition.

    I received a text at 3PM with these 2 pics. Mind you, I was in a meeting with my fiancee and the event rep for my upcoming wedding - we were sorting out the menu etc. Needless to say I got in trouble with the fiancee as I was paying more attn to my phone than the menu...

    Anyways, yes - I was lucky to catch this before there was total VANOS failure which would lead to well...a full rebuild. We have not seen a ton of these fail, but we do know they are just another E46M3 weak point. On our FB post the owner of Performance Technic in CA said he has replaced 15 in just 2 years!

    Looks like I will just replace with new OEM equipment. I might have a new one cryo'd...we will see.

    Lucky it didn't take out the motor. Install Beisans oil. I believe someone is selling a exhaust hub for about 300 on 1 of the other forums. Would you like me to link it here?

    Yep, much better this way.

    Thanks for the heads up man. We have a bunch of used ones in the shop, but I am paranoid.

    We will def drill the oil pump disk!

    When I see this stuff it makes me worry about all the things that can go wrong with the S54. Not to mention I have an SMG which compounds the worry! Happy to see you caught this - I need to check mine!

    Finally a free day! Been driving the shop E90M3, but I miss my E46...

    Uprated VANOS bolts to 12.9. Say goodbye to failures!

    Re-drilled oil pump disc. The stock hub tabs often break due to excessive 'play' in these holes. We re-drill them for a tighter fit.

    Since we had to drop the pan to find the broken tab it made sense to upgrade to VAC coated bearings and ARP rod bolts.

    Oh, since the stock oil pumps fail way too often, it also made sense to upgrade to our badass high volume oil pump that features our upgrade kit.

    I wish. I was very tempted to walk into the stock room, grab Schrick 288/280 and DLC followers.....but I resisted.

    I'm doing all the maintenance stuff now. I need to talk to Karl@Active for a nice tune - I want to see what I can make before adding headers!

    Cool. I think most of the other ones do. I don't have any amps or anything, but I have factory NAV, Bluetooth, TV Tuner and Sirius. I figured that this might be better. Next mod!

    Word. I got back from the PRI show yesterday and drove my car for the first time in a few weeks. I've been driving our stock DCT E90 M3 when my car was down... but I really missed the E46....hard to explain.

    Prototype VAC double adjustable suspension goes on soon - perfect winter mod ;-)

    Ha yeah, I have driven both and the e46 is just better IMO. Feels more unrefined.

    @Mike@VAC great to hear you are back with the E46 M3 and running strong.

    Sorry I did not get a chance to formally introduce myself at PRI over the weekend. We literally exchanged a couple words, then you had to part ways before I got to introduce myself. I decided to come back later on in the day, but you weren't around Click here to enlarge

    I cannot wait to hear more about these VAC D/A dampers! Hopefully we get to chat and catch up soon.

    PS: I was one of the loony guys discussing swapping a S62B50 in an E46 M3.

    Sorry to hear about your vanos OP but it looks like you are more than set now. Mine went out too not sure when but I discovered it around 50k miles. I don't think I can't post pics yet but my tab was lodged by the chain guide. I got really lucky.

    Did you replace the upper chain guide too while you were in there? Those are a common failure too.

    An S65 swap makes infinitely more sense.

    That would be the dream! But we're doing the S62B50 for several reasons:

    1) Cost. My buddy got a S62B50 for an incredible price.
    2) We'll be competing in NASA GTS3. Since we're limited on top end power, we want to maximize area under the curve.
    3) Swapping in a S62B50 will be a lot easier from the tuning and electrical side considering it essentially uses the 'same' DME as the S54B32.

    When we start actually working on it, I'll make another thread for more fun discussion Click here to enlarge

    I see, makes sense.

    If I could build my dream M3 it would be an E46 M3 CSL clone with a 4.6 liter S65, Schrick cams, dry sump, and 9000 rpm redline.

    Oh, nice man. Crazy show for sure...still mad about the $#@! location we were given.

    No matter what you guys decide on be sure to hit me up. I think our PRI display explains what we are all about... we are a lot different than most vendors out there.

    I'm going to do some AA software next week Click here to enlarge
