Crankcase ventilation.

Open breather on one side is incorrect. The valve cover breather for the PCV system should be a closed type with a hose nipple that gets a hose routed from the breather to the bottom of the air cleaner. Then you will have a complete PCV system, instead of gettin that "buildup" all over your valve cover from an incorrect open breather. You need a complete PCV system, not incomplete.

Something like this for the under side of your air cleaner:

Breather Fitting

Something like this for your valve cover:

I have another question not looking for competition performance just common sense opinions, this is a RHD car so the oil filter would foul the steering column in its usual position, so from the factory it came with the filter remote mounted next to the alternator with a rigid pipe set uprunning up and over the engine past the carburettor. So far so good, but this position puts the filter up high and upside down, so I’m wondering is this perhaps not ideal for best function of the filter? A quick fix obviously would be to extend the rigid tubes with a remote mounting kit and locate the filter right way up on the side wall of the engine bay, I wonder if it’s worth it.
