The issues in question, was a cracked head. It also had a blown head gasket, (Between 1&2) and the head had been burned away where the flame travel hed been.
The cause of the water was the crack.
When I used a b110 inlet manifold on a 310, I had to run the boosteroff the pcv port. I blocked off the rocker cover hole, and ran the lower breather port into the air cleaner. I found that there was quite a lot of "goo" forming on the underside of the filler cap. So Then I swapped the hose onto the rocker cover.
Anyway, a well used motor will generate H20 in the crankcase. Because H20 is one of the byproducts of burning petrol. If your goo is coming out as milky goo, that means it's probably from blowby. Mine was clear in the sight glass, with a thin layer of black (oil) on top.

My 63 bluebird 1200 ute only has a breather (No Pipe, dato's at that time wasn't fitted with breather pipes) on top the engine cover & covers oil over the cover & l just wipe it away when l check the oil & water every second or third time, which may be every two months. And yes it gets milky & that when you change the oil in her about 1500 miles! It has 118,784 miles on original engine. The 76 1200 ute l have has 57,378 miles on it haven't seen any oil from breather & it not blocked (yes l checked). Oil changed 1500 miles too & both good the fuel too. Bruns

the early datsun also has the same breather pipe, on the A10 in a datsun 1000 at least

I agree with not venting to the road but some cars came that way standard, eg early holdens. They had a tube shaped like a walking stick that came out the top of the tappet cover. I wonder if that would pass current ADR's

Don't vent it onto the road! Atleast use an old plastic Coke bottle or some other cheap/free container mounted in the engine bay to collect the oil. It'll cost you stuff all both in terms of dollars and time and is the right thing to do.

They will want to see it vented just like A14force described " vented back into the air cleaner "

i wouldnt be worried so much about bikies but the authorities, i got defected for this amongst over things, and u can cop a maximum fine of 22000 dollars, i only got 200 fine but if u try take it to court ull cop it.

just wondering if anyone has had a car engineered with a catch can im just wanna know before i go trying to get it engineered with one and they wont let me.

Quote: If this is a road car, then just be carefull that the local motorcycle club doesn't find out who you are or they may just come around & jamb that breather pipe up your ignorant a*se. Oil spilled on the road surface is not the motorcyclists best friend, particularly in light rain & they have as much right to be safe on the road as you do.
Get a catch can & use it or restore the PCV.

I wouldn't be too concerned about that.
Ona race car that is only started occasionally there is bound to be a lot more condensation under the rocker cover than in a daily driven car. And after 60 hard laps I don't think 30mL is enough to worry about. Just my 2c. How much faster are you going after a day's practice???? Thats'd what I'd be concerned with!
