Sorry for delay in response. Thanks for your kind offer, however I have an old oil pump to test out. The pump in my car for 20W/50 seems to be holding up in the garage so we hope all goes well on the road. All the best for the new year. Old Alffetta's are thin on the ground in Australia and when you do happen to spot one it's likely to be a couple of years till the next sighting. This is not surprising given the parts to keep them going are hard to find and outrages prices dealers demand. $1.95 oil pump 'O' ring was sold at $20 locally. A $4.95 exhaust valve guide from a dealer can cost between $20 to $30 for a single valve guide. Hope things are a bit more sensible in Spain.
Au revoir and thanks for your interest.
