I'd like to replace this pipe, p/n 96420725711 I think, probably over the winter. Does anyone know if it's possible without removing the heat exchanger?
To get the heat exchangers off I'm pretty sure I'll need to go to a specialist, so need to plan ahead if that's the case.
Heat Exchanger needs to come off. It's a large nut on the passenger side of the engine and you can't get a wrench on it without the heat exchanger off.
I took the car to a local independent today so they could assess the work needed to remove the heat exchangers. Plenty of corrosion (UK car for 30 years) so they said the chances of snapping a stud were reasonable.
However, they also said that nut on the oil pipe would come undone with the exchangers in place, so I might try that first. They did warn me to be careful not to damage the block however, although I'm not sure how that might happen.

That's BS. Find another shop that knows what they are doing.
Removing rusty heat exchanger nuts is a 3 handed job performed with a socket, extension, ratchet and as oxyacetylene torch. The nut is heated to cherry-red, torch pulled off and the socket slapped on immediately and is quickly removed. The nut makes a lot of noise but it comes off and leaves a clean thread behind.

Not that I want to wade into the middle of this but I don't think it's wrong of them to tell him what could be possible. FWIW, I've had to replace that exact same oil line and had to have the exchangers removed and was given this exact same advice from two well-respected air-cooled engine specialists/builders in SoCal. In my instance, none of them snapped but I don't think it's bad advice to warn that it is a possibility so that a customer can make an informed decision up front.
