Went for a drive, lost power and now car exhaust sounds like it has cams

[karter16]

If they did not remove the securing clip for the oil pump disc and left the VANOS unit completely stock, then there might be a problem with that VAC exhaust hub. Otherwise, it would be an installation issue like heinzboehmer said.

In your picture, I cannot see the securing clip or washer for the VANOS oil pump disc. That is a strong clip that retains the ring that has now fallen out onto the exhaust hub.

Haha touche

These photos seem to show that the retaining ring that holds the outer race of the pump disc has popped out and the outer race is what he's moving with the pick?

If so it seems possible that if the retaining clip wasn't seated properly that could have caused the rest of the destruction subsequently?

It's been a while since I did mine but from memory that seems plausible no?

I'm not sure what the term is for the part, but that is the ring that the four oil pump pistons push against and it rides on the needle bearings in the VANOS unit.

Yeah agreed. If that retaining clip wasn't seated properly, or the oil pump pistons weren't seated properly then that could be the cause of this too. The “bearing” damage could be subsequent to that. All depends on exactly what OPs mechanic did/didn't disassemble.

Update from the shop:

So what happened is the piece in the upper right came out

What is odd is the snap ring is still in place.

All the needle bearings are out in the oil pan so we are going to need to flush the engine oil

The Beisan vanos would work and we can flush out the oil pan.

The snap ring isn't in place in the photos you posted earlier.

Edit: unless it’s part of the needle bearing casing?

No idea but I just ended up buying the Beisan Vanos unit and their exhaust hub and having it shipped to my shop. Hopefully after that my Vanos issues will be fixed.

[jpy1980]

It does not come with exhaust hub. Since you already put a $700 upgraded VAC hub on the car I assume you want to keep it?

Call up beisan and see if they can sell you a rebuilt VANOS with tbd OEM pump disc hole size.

Thanks for this. I ended up just buying their exhaust hub as well as the unit itself. My VANoS system should be bulletproof now right? Haha I even changed out the solenoid stuff earlier too!

I shall have a slightly used VAC exhaust hub for sale soon. Didn’t want to mix parts.

thanks for the help!

Not sure how that is physically possible if you look at how it is assembled -

Exactly - something doesn't add up

Yea not sure what to really think. I don't have enough technical knowledge to refute what they are saying. Once again, this is a very well known and popular shop in SoCal so I doubt they would lie. I've been going to them ever since I had my f80 years ago.

I guess I can find another shop after the fact, but I already bought the needed parts and they just need to install it and be done.

Anyone know of a shop more dedicated to e46 M3s in SoCal, particulary in LA? My friend mentioned JMP but any more recs are welcome.

This video explains the components and how they are assembled, skip to 8:40 -

For major or technical work, it might be worth driving to Kaiv in SD.

There’s a guy in Pico Rivera that is a killer with VANOS work. He’s a Beisian-certified VANOS technician (I think that’s what they’re calling him).

Got it. Do you have their info?

Lama from beisan sent me some recs too. Odd that the pico rivera guy isn’t on the list below:

Here are some shops. Just let them know you spoke to Beisan systems and I recommended them. And they will take care of you. Best of luck. And let me know if you need anything else.
