Liam,
Wow, thanks for the offer of the cherry picker and an extra hand. At
this point I think I need to keep it simple and drive until I really
have to pull the car off the road to fix something serious like a
major oil leak or gearbox. I am enjoying driving it too much to pull
it to pieces unless I have to!
On that note, how do you recommend I discover if the tappet vent pipe
is clear? Getting to the top end looks tough at first glance without
removing the carbs. At least the bottom end appears NOT to be full
of road debris. Can I assume it is unlikely to be plugged further
up? What would be plugging it? What next?
Care to rendezvous for you to test drive the car and give me some
feedback on the condition of the gearbox?
Cheers
Mark
