FTP AIR/OIL separator & 55K motors? Real issue?
After reading up in this thread, curious what others here are thinking?
https://mbworld.org/forums/w211-amg/...55-down-5.html
Is this really an issue for us 55K folks? Thinking Bramage might be onto to something, especially for those with mod'd motors. The last time I removed my surge tanks there was some oil in there. Of course all cars have some on the TB.
Though I initially skipped over the listing below, now taking a second look, I mean hell, for $150 or so with shipping, if it helps............Not sure how it would help with crankcase pressure as I see no venting, unless it is based purely on less fluid restriction.
Thoughts?

They Help relive oil in the intake system from gumming up engine components and helps with crankcase pressure. Within a few thousand miles pop your catch can off to see the oil you stopped from going into the The engine's top end and gumming up the T/B, Surge tanks ETC.
Features:
-100% Bolt on No modifications Required
-All lines cut to Size!!
-Billet CNC 6061 Aircraft grade Aluminum
-O ringed removable twist off bottom
-Strainer built in internally

I am not exactly sure what you mean, but there is crankcase ventilation (PCV). (I know you know this,so I must be misunderstanding your question...) ....
On a possibly related note,I noticed that I needed to add 1.5 quarts of oil. I will be checking the PCV and would like to install a catch can. I have not looked at the surge tanks or throttle body, but I am guessing there is oil ....

I've been running a VRP catch can for a year and a half. I can say my tanks and IC are extremely clean vs without it so its serving that purpose. I haven't on the other hand understood Bramage's point. Only time crankcase back pressure is problematic is when it's too high or closed but in all cases that I believe were described, the case is open so not clear where the improvement is coming from.

I had a catch can for a while and yes it did collect oil. Now I just have a breather filter connected to each hose.
So the answer to your question PP it is worth it.

Custom Corvette Accessories also makes an excellent unit. Small enough in diameter to fit against the firewall by the aux battery.

I ran a hose off each valve cover to a catch can venting to atmosphere. It didn't collect very much oil at all but was only on for a few hundred miles. oil lowers the octane of gas when it's going thru the intake and can cause lean/detonation conditions. It also helps by not having the hot oil vapor heating the intake charge also.

As Ahmad said a vacuum pump will end 99.9% blow by/crank case pressure but isn't easy or cheap and requires rebuilds. Are engines are built tight to begin with so the catch cans will be enough for most.

But I am glad more are questioning why we are not running at least 2 catch cans - (1) for vacuum (crank) and (1) for boost (heads)....I guess you could use one can and three lines with valves in them...
I'll have to look at the available space but it sounds like we need three cans ideally....

Just remember that the crankcase ventilation is designed to circulate fresh air through the engine. The large hose on the left side valve cover is the fresh air supply and the small hoses are vacumme. If you stop this circulation you will have a moisture build up in the engine. Lots of peanut butter oil. I've seen it before when a catch can is installed improperly. Just make sure you hook it up inline with the small hoses and either put a breather on the large hose or leave it connected to the air box. Otherwise you will do more damage then good

I don't think venting the valve covers to the atmosphere is a good idea...unmetered air will enter the engine and cause issue when in vacuum.
But I am glad more are questioning why we are not running at least 2 catch cans - (1) for vacuum (crank) and (1) for boost (heads)....I guess you could use one can and three lines with valves in them...

Catch can seems to work fine so no reason to change it.

We don't run MAF's so don't really need to worry about unmetered air. I was going to route it back to the intake but didn't see a need to do so. I've tossed the idea around of putting a vacuum pump on the new build but don't see it being very practical or needed honestly. The single

No I need to find a schematic because when I popped the hood, there was a lot covered
...stupid plastic covers ...So there should be a vent on both valve covers, right ? And then one from the crankcase, which leads to the PCV ?

I thought the e55 was MAF ....Interesting....

There is breather from each valve cover that y into the throttle body and another bigger breather on the drivers side that connects to the intake

Beat me to it. I plugged the smaller outlet on the drivers side then ran the lines into the moroso catch can (found a billet one for a hemi that worked great). You could vent both line to atmosphere I guess or put breathers on them but the catch can catches to oil vapor and dosent steam like it would just coming out of a hose.

Our Catch Cans are actually on sale right now. Visit our website they are under $100
There is no need to run 2 cans because as BlackBenz said you T into the Valve covers. Our can collects oil that would have made its way into the T/B, Surge Tanks, Etc otherwise. They work and for the $$ you can't beat this simple mod.
