Question about VANOS issue
 
Hey

I read this thread and I just wanted to make sure that if you ever get VANOS issue with the car, it's my understanding it'l only require a expensive but not disastrous fix? Like, it won't destroy or wreck the engine like the rod/main bearing issue on the E92 M3s?

Well, if any part of the broken hub tabs gets down and wedges on the timing chain, you will have catastrophic engine failure. This is the reason why most of us performed VANOS lock-down using Beisan kits.

Shoot. Man, wanting to own an M3 isn't easy huh. It's always been my dream. The E46 being 15K cheaper than the E92s, hopefully it's the right choice.

Is the job easily DIYable? If you compare it to rod bearings for example.

It is with patience and tools.. stuff like this is why e46's work *great* as a second car :)

Yeah I know the reliability isn't optimal compared to E92.

But I don't need a DD car in the sense use it to go to work. Only to drive for fun and do the rest.

Well there you go - if you have the opportunity to just make sure you have the tools listed in the Beisan procedures, crack the engine open, take your time, and have the car down for a weekend or two, I say go for it.

Yeah that's the thing I'm a bit worried about internal engine work to F up something but I'm sure following the DIY it should be fine.

The only other thigh I want to figure out before is the damn subframe/RCAP issue. There doesn't seem to be a clear solution as of yet? At first I thought those reinforcement plates did the trick but apparently not in another post that seems very thorough? I don't want to discredit the person since I'm new on these forums but is true?

Re: Question about VANOS issue
 
Where are you located? I have a 2002 M3 for sale. Vanos has been done last year. Bearings are good as well. No sunroof either. Now as to subframe mounts. There are many ways to repair. If your car isn't rusty and you do not have cracks in the mounts you have a number of options. If it is already cracked, then you pretty much have to weld up the cracks so then you might as well weld on plates as well. When I did mine on my other M3, I used epoxy and stainless rivets and made my own plates. I also extended the mounts right through into the trunk and back seat area. I then made special brackets and riveted them on as well. I usually go for over kill then I drive like an old man because......well, I am!
There are many threads on this subject. Many ways people have repaired, fixed and generally redesigned the whole area. Pick one you are comfortable with and do that one. Good luck.

I'm in Gatineau/Ottawa, I see you're in Calgary, that pretty far haha.

Yeah well, I guess I'll go with VinceBar thing since he sells kits and all that. I'm currently catting with him by email to get more information on the process.

And there isn't any issues with the rod bearings right, because when there was that service announcement, the new rod bearings put in place we fine huh?

Re: Question about VANOS issue
 
Re: rod bearings, treat them as a wear item. Take an oil sample at oil change and have it analyzed. If test results are good you are fine. If not you will need to change them. If you wait and spin a bearing then it means a complete rebuild, which I di or buying a used engine which most people do.
