Lauri,
High milage engines can produce so much blow-by that connecting them to
a PCV system as you have done, can make the engine leak due to high
crankcase pressures.
Also you must use an oil seperator between the side cover and the PCV valve
or else you will be sucking in lots of oil laden air, which will foul your
valves and plugs (good for compression though...)

Hullo,
I did a conversion which seems to be not so wise. It may be much more near to
idiotic.
I FOUND A valve from baby Cuda's intake manifold, screwed it to my intake
and connected it to ser 4's valve cover (tube connection at the oil filling
neck). I had some idea that it could burn those gases etc. fumes and make some
vacum inside the engine thus minoring the oil drippings all around.
But I did not block the original open breathing tube from the sump (via lifter
cover). I am quite sure that minor problems in idling and at run at low revs
is due to "wrong air" coming from crankhouse to intake manifold via pushrod
tunnels. I have fitted a ser 5 manifold with Z-Strombergs, which use intake
vacume to operate.
Any comments?
