Hope the air line clears it and makes it all dandy again.
I am seeing my eccentric scrap yard owning mate tomorrow who seems to have or know how to fix anything.
In his "out of bounds" sheds lurk all sorts of NOS "new old stock" (not fast gas) parts from years gone by... will keep you updated.
I hope my airflow meter stripping antics yesterday dont fail me. She still runs fine and all the little wires were ok.
Belts and tensioner change on Sunday should prove interesting.. Record is 2 hours.
Should I do the water pump too? Last Nissan outing in the Black Estate involved pump failure 2 days after belt change, meaning all had to come off again to get to it... 2 days before departure for LM 

I think thats a yes!
