Vanos Covers

[sergbaja5t]

How good are the vanos covers from Evolve? Im doing NRW valve covers and plugs and everything related very soon. I might as well do the vanos covers as well. What are y'alls thoughts?

I’m doing the same thing and I have the NRW valve covers, NRW billet spark plug tubes and the NRW gasket kit.

I’m also doing the throttle actuators (better rebuild ones) at the same time, as well as the vanos covers. However I opted for the Mporium bolt on vanos covers, I’m not saying the Evolve ones are not good, but the bolt on ones from Mporium look to be a better solution in my personal opinion.

The Mporium ones are a bit more labour intensive to fit though, as they require the motor to be re-timed, as they involve removal and replacement of the vanos stretch bolts (if you get the complete kit from Mporium it includes OEM stretch bolts and also the gaskets for the vanos cover housing).

Re-timing the engine is something I don't want to do right now. I kind of want to keep cost down, as I am putting back capital for an F80 in the very near future.

I have a friend whose Vanos unit spring exploded and put a hole in the valve cover and upper timing cover. After seeing this I don't think the clip-on covers can handle that force. Something to think about.

Your friend had bigger problems than his choice of vanos caps if his spring exploded. The plastic caps would never have prevented that either. Nothing short of Carbahn or Mporium caps would have worked but again, what causes the spring to dislodge in the first place?

I’m going to get my vanos covers changed and NRW valve covers fitted.

Can this be done without changing the oil - or does the oil need to be drained? I’m asking because my oil is only a couple of thousand miles old, so if it doesn’t need to be drained I’d rather leave it.

You don't need to change engine oil.
