Boost also tends to pressurize the crankcase to a certain degree...since flow will take the path of least resistance and with crankcase pressure assisting, the stock system is adequate. Putting a PCV valve in the location I mention will help though...if you are going to install a catch can...
Dude - there is no PCV valve on a 7M...the throttle body uses a TB orifice. You should know better than making a statement like that :3d_frown:
Here's the TSRM depiction of the orifice...very often it does need to be cleaned...
The reason you get so many "opinions" is guys seem to route the PCV system on the fly...basically whatever looks good or offers the most convenient hose routing. The problem is these same people don't know how the PCV works on the 7M...kinda surprising since it's such a simple system.
A few...
Take the cam gear cover off and look behind the gears at the cam seals. Otherwise, there's the oil pump drive shaft seal and the main seal for the crank...both are behind the lower cover.
Call up Martin. I needed a shifter seat for my truck and the guy I talked too told me how to figure out which one...seems the W56 has a couple different variants. Once I pulled the boot and took a look, he had the right one on the way. I got the fork bushing too...using both really tightened...
Yep, the $15 one...I did not use the smart connects. There is plenty of rubber hose on the return line to the resevoir....3/8" size. Standard or constant force clamps will work fine.
I would do a flush/fluid replace with Mobil 1 ATF (Dex V synthetic) and put this filter on. Change the...
Seafoam = snake oil...it is a solvent. Never use this stuff in the oil or fuel system...in fact, never use this stuff period.

You can get the exact same result by metering a quart of pure water into the intake manifold...ever seen the cylinder that blew on a BHG? Clean as a whistle. A TB...
There are no stupid questions, only stupid answers ;)
Learning how to search will help along these lines...read the search tutorial in the Intro section stickies:

Also, try to post using complete sentences with correct spelling...
First of all the 7M uses an AFM (Air Flow Meter), not a MAF...I really wish you guys would keep that straight.
Terminology is important...if I see a guy that can't write a legible sentence using correct terminology, I ignore him.
Second, stock head bolts were tested by Reg Reimer to 72...
1) Fuel cut. Lex AFM = 16-18 psi or go standalone.
2) You will either need a fuel piggyback or go standalone.
3) Depends on the motor...take it to a dyno and find out it's limits.
That engine is known for that. Causes? Contaminates in the oil from combustion...water vapor is the primary culprit. A working PCV system is designed to get rid of combustion byproducts, but if it is not functioning correctly (i.e. under vac) an emulsion can result a lot like what you see with...
