Weistec M156/M159 Oil / Air Separator
Always use RON 98 octane. Never uses oil either, have never had to top it off between oil changes.
Car is used as a shopping cart. Lots of short trips.
Should have bought an ML320CDi

Apparently its common on E60 M5 V10's as well.
The only person to buy these will be one that enjoys spending time lighting their money on fire or enjoy having their intelligence insulted for a past time.
$530 for a catch can is a joke guys. You need to get real and not hose the members you sell too.

My thoughts exactly.
Theres cars on here with $6k rims, tunes, $2k carbon airboxes.
WTF is $500 to help your engine? You could make something up alot cheaper but you could probably sell this in the future for a couple of hundred bux and get some money back.
Do Weistec send out instructions for us DIY'ers?
As for the price, I don’t know what it cost to make the final product, and provide some source of income to a company that has bills and employees to pay, but outside of the development and engineering and material costs which is part of the final price, and this is not a simple “let’s see if this off the shelf unit fits” approach, appears to be about right, though I would like less cost too, but not less of a product. Sure if they sold thousands of these, they could spread the costs down the line, but that is not the case here. The unit looks like a rather intricate and solid proofed out unit, fully able to be disassembled (that costs more than just a catch can with a drain valve at the bottom) and quality material+finish, construction and fitment hardware, though it would help to see one on the site installed/maybe in the works. Would also help someone to know something about the simple aspects of it like; easily goes in-line with the OEM crankcase ventilation hoses, and mounts cleanly and in an easy to access location (also for removal of the can during inspection and draining). I see bolt holes in the side, assume there is a mounting bracket, but not shown, yet?
Nice product!

One other thought, this product should be used on even non-modded 63s in my opinion, my 63 would "burn oil" even when it was stock, being nearly a quart low at my initial 1000 mile service. After seeing the photos posted here and on another forum I now see where all that oil went. If a $500 part can save my valves and MAFs that's a no brianer.

There are people with money trees that basically do not care how much it costs and there are others that compare products across other brands.
I do believe there is a huge MB tax for all our products.
I debated that with the headers, X-pipes, and CArbon fiber products.
Let the free market roll and let demand dictate the pricing.
If there are enough jrcarts out there, then Weistec will sell them at the price they ask. If not, they will learn a lesson.
It does look like a well thought out quality products so props to Weistec on that.

Why do you guys think your motor is that cheap? My dealer had to replace a motor on an E550 coupe parts and labor were 50k and thats warranty pricing.... Lots of cheap skates
. The good thing is it’s just a small minority that make the most banter, and the majority reading but not posting I am sure are intelligent enough to see facts and decide for themselves
. Difference of opinion is one thing but you guys just sound like you are playing devil’s advocate or trolling, and not worth the time of those actually contributing to the value of this topic in further replies. Does not upset me, go ahead and trash the subject at the end here; the only time having the last word will not mean much! The better points were already made in the beginning and will be there to serve those that want to learn. I upped the ante at the end here to set the mood straight before I leave
, see if it wears down those that like to flame
. I have seen this sort of flaming rebuttals more than is needed, but on the Honda forums and such, where you expect it

I'm not likely to keep my car after warranty (especially in light of the cam/lifter issues) so I won't be buying this piece, but I agree with others here about the economics of manufacturing a quality piece that will not be sold in huge quantities, hence the price. Maybe Weistec could offer financing for some
Weistec is all about quality...one look of what they have done to my car and you would see the professionalism in everything they do.

im sure its a great product. i own a top of the line manufacturing company and i mark-up the s|-|it out of things because people will pay for it. i know all about that stuff. i just dont think that this particular product is worth 500 dollars. this is a discussion forum and we are discussing it. there is no need to insinuate that people are poor and should shut up.
that being said, its good to know that weistec is a quality company and i will definitely look into there products when i start doing some mods on my new toy

Some will buy this no matter what due to need or perceived value. Others won't buy it at pennies on the dollar because they feel it's unneeded or they have other financial priorities.
Suppliers react to this and raise and lower prices to sell for what the market will bear.
Personally, I would like to see some test results on the effect against the stock situation. Then I can make a cost/benefit decision.
But for the work invested for my own swag on the number that will sell in 6-12 months, it seems to be within a fair profit margin range.
