Why can't someone make one of these for?
 

Our amg's? Nice, simple and clean. http://store.blackforestindustries.c...ccacroils.html

They do and you can take a much cheaper one and get the same results

Show me one made simple and clean like that one. 100% bolt on. I'm not concerned with the price.

needswings makes a nice kit for the m112 s/c engine. about 110$ im sure they could do it for yours if they had a car to look at. located in warren michigan

just buy 2 of these and hook one up on each side,this way you wont even have to get under the tb.

You don't need 2 catch cans. You only need to hook up the 5/8" nipple on the drivers side valve cover. The other 2 small nipples on the secondary/ upper valve covers are for vacuum only. Little to no oil ever makes it up through the baffles in to those small valve covers. I can't believe that newb company made a catch can for 3 inputs lol.

They aren't for vacuum per say. They are the oil vapor to get to the highest point and connected to the intake so when the engine is creating a vacuum it pulls some of the vapor out of the crankcase. Go drive your car for 20 minutes and pull the breather hoses off and look at how much oil vapor is coming out of it. The best thing is to run a line from both valve covers to a Y and then into the catch can and back to the intake.

I have, and their is no vapor. That escapes through the larger 5/8" nipple. As a matter of fact when I removed the secondary valve covers they were dry as a bone.

There is oil coming from there bro.

Not on my car, the hole is only 2mm in diameter.

that wouldn't make sense because where would the oil come from when the breather covers leak, which these cars are notorious for.

Might look dry because oil(fluid) dosent get in there but the valor does. If you have no vapor then don't worry about a catch can.

No idea.

I need a catch can for the 5/8" nipple only.

Weistec has one for the 63 engine: http://www.weistec.com/m156os.html

That's real nice.

I think the 5/8" line main purpose is too allow air to be drawn into the valve cover to offset the effect of vacumn from the PVC process? They are normally connected to the intake to capture the oil vapor escaping back out the hose during low rpm.

I don't think so, because it is plumbed right in to the throttle body.

The 5/8" line on the drivers side valve cover is plumbed into the air intake before the TB (ambient air pressure).
The PVC system is after the TB pulling engine vacuum.

I got my catch can for $30.
Cleaned and polished the internals then added one of these. No more oil gunk back into the S/C and TB. No CEL and drives perfect with the S/C wining like a ***** :y
