G'Day Lang,
Thanks for your tyre offer (pm sent). Coincidentally Motto called in here two days ago on a camper van tour of New Zealand and we gave him a guided tour of our LRDG truck and workshop. Your comments about Chev 216 oil pressure are interesting. Our motor runs at 15 to 18psi when cold and we have not yet run it hot to see what happens then. But as the long-time owner of a Model A Ford pickup truck
I have complete confidence in splash lubrication.
