Picking up a '72 Westy Tin Top on Friday! My last bus was the same model but with a T1 engine and that was 25 years ago.

I know that I want to replace the missing body to engine seal first. Since I'm new to the T4 world I'm wondering two things:

1) Is there a better/worse seal?
2) Can you replace the engine seal without removing the engine?

Looking at the engine removal process on https://ratwell.com/technical/EngineRemoval.html it looks like it's possible but possible doesn't always mean sensible.

You can absolutely replace the seal with the engine installed - that's how it's designed. Rubber side goes down.

It's a pretty easy job.

It can be tricky around the injectors if you have a fuel injected engine. I find one guy does the top and another helps from below using a long pair of needle nose pliers. Start at the firewall centerline and I usually go clockwise.

It's the same engine-bay perimeter seal as for the 1972~79 VW 1600 Type 2, which can also be installed quite easily with the engine in place.

When you someday pull the engine, first remove the seal and then mark the engine tin so you can trim it to give an even spacing all the way around. The seal will then go in with less effort and not be as damaged by time.

This is the right rear corner of my nicely trimmed engine tin, the gap is probably twice as wide as it was originally:

Old seals soaked with oil near the oil fill can be a fire hazard.
Let's not discuss how I know this.

What is the purpose of that white-spigot and small-bore black hose, on the oil-filler cap? I have never seen its like before! Confused

I am also wondering about the supplementary Earth / Ground cable to the aluminium cooling-fan shroud and the strange looking green connection on the right hand side?

I take air off the fan shroud, run it through a filter and feed it into the crankcase. The fresh air keeps the humidity within the crankcase lower so there is no build up of condensate even during the coldest weather I drive in. Been doing this on my VW aircooled engines for nearly 45 years. Originally saw an article on doing so in some VW specific publication. The small size of the white fitting acts as a restrictor to keep the volume of added air low so you don't start blowing oil out of the crankcase. The system if pretty maintenance free, just a new filter every 50-100K miles.

I think this might be similar in principle to the PCV system that is used on the VW 411/412LE engine.
