This may seem a dumb query, so please excuse me in that case.
After a series of dramas with starters, solenoids and oil filter bases I have bodged enough bits to run my Mk3 for the third time since its major re-build.
During the downtime it had wet-sumped. I drained 1.6l from the c/case and replaced it in the oil tank - which then read as overfull!
After starting and running it for five minutes, checking scavenged oil rate into tank I stopped engine and checked level - half way between marks! Must leave quite a bit in the cases and circulation.
My most concerning thing was the volume of air coming from the breather in the neck of the tank. If you place your hand near the neck there is a very noticeable strong airflow out. Is this normal? All the threads I can find refer to c/case pressure. I ended up running the tank vent straight into the back of the pancake air filter. All this air would be flowing in there when the cap is on the oil tank. I am not sure what to make of this.
