Hi all
Engine is a 1973 2.0 with a 2056 build. I purchased a cam that was more aggressive for spirited driving no track and just large enough to maintain the car running fuel injection DJet. New heads with no vents.

purchased the oil tower and air box for a 1975/76 as the bigger breather opening was recommended.

I am still experiencing some oil leaks one that sits at the base of the head near the number 4 spark plug. Plug is not leaking. Also some oil on the thermostat spring mechanism.
Valve covers have had inner lip welded and 914 rubber cork gaskets.
I bought this canister to help with the pressure and hopefully remedy the oil leaks.

I have been unable to find an example of how to route the hoses for this when installed.

Any advice or pointing me in the right direction would be appreciated.

Bingo! That's a great article!

Only one GLARING difference on that engine though...

He's dry-sumped!

He's got a built-in vacuum pump!

Dry sumping any engine changes the "hurricane inside".

Now the bit about venting the heads was worth its weight in gold...

Just created another question for me.

Anyone created a dedicated drain back from the heads to the crankcase?

Pumping all the oil in the engine up into the head IS a problem for early American V8 stuff. I always hog the shit out of the drain back ports on those. This is even more critical with high rpm and high flow oil pumps.

Another thing, just remembered...
Every single dry sump equipped engine I've seen has a vacuum relief valve (sometimes adjustable!) somewhere in the engine case. Normally valve cover based in most examples.
I thought that was SOP for a dry sump.
