I get both sides of the argument, but things always improve, you don’t get a new car when the new model comes out.

Even though the engineers have concluded and confirmed that the Alu covers do not have any flaws other than they fact they do not believe the Alu covers are “Lifetime” part. Rather they should be treated like a wearable item and change them out. Aren’t the bearings in your car the same way? So that’s nothing new. Since SLON, VT, Evolve or EPM never claimed that they are a lifetime part, I don’t see a problem. The stainless steel versions are a “Lifetime” part. That’s the main advantage of the stainless steel version. Plus, since the tolerances are so tight, I believe a metrology lab report is necessary for each unit to ensure there is ZERO machine or human error involved. These are two advantages over my original aluminum covers and the other covers on the market. Did BE offer a replacement for people who installed V1’s of their bearings? Or did they offer replacements for ARP bolts that they used initially that were Chevy ones that they cut? No, they didn’t. But that’s not the one way I operate. I’ve already emailed my customers and am offering a rebate for the covers when they come out. So don’t worry about it. I’m on top of it. |

Having seen alu vanos covers fail in a short time (not specifically EPM sets), and having seen loose EPM covers I would disagree with your statement above. A recall is the responsible thing to do. But you do you.

No real concerns about the added weight of solid stainless steel compared to cutout aluminum or the original plastic? I would think there had to be a reason BMW used plastic.

Why does BMW opt for cheap plastics when there is a durable, permanent, metal alternative? Bean counters. See their cooling systems.

I think the primary motivation was weight savings. Similar decisions made by Audi on the S4 engine from same era. Their plastic rails and timing chain guides / sprockets ended up requiring the motor to come out to address around 100k miles. I assume plastics are still going into engines but more durable options now

In my experience with product development, the cheaper play at scale will win out even at the expense of durability. I would bet money this is the case over weight savings.

Going from plastic covers to steel covers increases the angular momentum and rotational inertial loading of the covers by a factor of ~10. Angular velocity at redline is ~71.7 rotations/sec = ~25,810 degrees/sec (camshaft rpm = engine rpm / 2). Plastic was selected to minimize the inertial loading generated by the covers. Basically, they minimized parasitic losses.

I wish plastic replacement covers were available to avoid redesign issues. I certainly would not complain if I had to replace them every 10 years. This part does not have to be "permanent" because it is very likely that the valve covers will weep within that 10 year period anyway. Just pop new plastic ones on at that time and be done till next time.

Watching these Vanos covers getting machined is so satisfying! Many of you have been asking me about putting your order in to purchase them. I’ll update you guys soon.

Abdul, instead of creating new products you should fullfill the orders of other products you took my money (fuel filter) since many months you never shipped and since 2 months you were supposed to send me. I have asked you last week to refund me by email and you never replied to me. Do not ship. I want my refund. Sorry but please reply to my email

I especially like trying to advertise new products in a thread about the potential flaws of your prior version.

Abdul Hi Abdul, your PM box is full.
I am following up with you to get an update on the billet silver valve covers that I pre-ordered. I was told 4-6 weeks and am just checking in on things. I messaged the EAE instagram account but got left on read. Kindly advise. Thanks, Alex
