Too much pressure?, Still leaks some Options

[Wew]

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.
