[Mgs] PCV question

[PaulHunt73]

You are describing two types of crankcase breathing, which should not exist on the same car.

The first from inception to Feb 64 used a hose from the rocker cover to the front air cleaner.

The second from then to Oct 68 used a PCV valve on the inlet manifold with a hose going to the front tappet chest cover.

The Y-connector Max talks about was only used after that when the tappet chest cover was plumbed to both carbs in place of the PCV valve.

But oil loss on the starter side won't be anything to do with that anyway.  More likely to be something to do with the filter/filter head perhaps a seal blowing under higher oil pressures and hotter oil, oil cooler connections if present, or oil gauge connection.  The latter is right above the starter of course, but at speed oil is going to be blown back anyway.  Could also be rocker cover.  Stuff that side of the engine with balled-up newspaper and that may help to localise the source.

  I have a '74 MBG engine with a '64 through '67 PCV valve on the manifold and connected to the front cover breather pipe.  I have a hose running from the valve cover pipe to the air cleaner.
  Seems to work fine for daily around town driving.  My problem occurs when traveling at 65 mph sustained speed for about 100 miles. 

  The problem is I blow out about half a quart of oil from somewhere mid-engine or back on the passenger side.  I can't find any obvious place that the oil is coming from but it seems to be concentrated near the starter.
