I have a very sick 1725 engine you could rob bits from and is soon coming out my white van.
It has a big end gone. It runs nice and smoothly until the oil gets warm and then you need ear defenders.

I think the sumps are different. It's been ages since I had the bottom end apart, but as I recall, the 1725 in my Funwagon has a very different sump than the one in my 1725 Alpine.
