The engine needs some sort of protection while the engine room is blasted. Martyn from MPS taped up the air vents for me. The rest of the engine is now covered in a layer of that heavy duty cling film builders use to protect carpet.
It was a job and a half getting it on. No space round the engine, attached at the bottom and really quite massive. Like wrapping the biggest, most awkward present.
One casualty was my thumb which suffered from cling film burn. Am also pretty sure I removed most of my fingerprints in the process…
