I have bought it also for my turbo project. I am waiting for my cherry bomb resonator & muffler so next month I will start to put it in also .

Good luck with your project will be looking forward to see it.

IFrom what I know M104 have 3 PCV routes
2 vents on the valve cover
1 tube that connect to the center of intake manifold

I have wandering web after web
but there is no specific answer or picture of how people fix it
how to route the line to a catch can

I wish you could give me some advise
I keep on asking about this question but no one seem to
explain it completely

Thank you very much

hope that make sense.

to only let the vacuum from the intake suck the gas in
but not allow the boost to push the + pressure back to the crankcase


According from what you said
seem like I already find out all of the PCV on my engine
Big thanks buddy!

Here is my little project that I started a while back on the old 300SE.


I was originally thinking of a supercharger setup but then decided to go with a turbo.




So as you guys would know the S class is a really heavey car so I thought I might get rid of some extra weight. As this is something to play around with none of the S cass features really mattered so out they go. this is ann older photo but the door trims and carpets are no longer there.


OK so it was time for the engine to come out and change to a 60-2 flex plate and modify turbo manifolds that I purchased from Clayton (bahaimus) that was originaly for his twin turbo setup.




After days of batteling with cutting and welding, I finally got it sorted and together nicely.



Ok just a few days ago got the engine back into its home and started on the intercooler piping




Ok so this is where im at now, I have the next 2 weeks to get as much as I can get done before im off holidays and start work again.
