Reply To: Dufour 38 Classic Engine Volvo Penta MD 2040 general overhaul or replacement

The Volvo MD 2040 should be identical in construction to the Perkins Perama M35 / is actually a Perkins engine.
The Perkins parts are much cheaper than the “original” Volvo parts and seem to be easily available: https://www.parts4engines.com/perkins-perama-m35-parts/
