I have done this, 400 miles up country in the Northern Frontier district in Kenya my Opel 6 Cyl, started to go wrong. I found out which cylinder and removed the two push rods and took out the plug and carried on. it sounded like a tractor but it went! After getting back I stripped the top end down and the timing gears. I found that the newly fitted timing gear had moved on the shaft and allowed the cam shaft to destroy a cam follower. The blocking ring, sintered metal had broken up and allowed the cam shaft to move.
My Son, a Blue water engineer was on the way to Santander from Dublin to deliver Granite chips. The Doxford 8 Cyl. engine had a piston break up and he took out the bearing cap and lifted the con rod up and secured it and removed the injector and bandaged the crankshaft and they carried on.
When this happened they were close to Santander and they dropped the anchor but could not touch bottom so all the anchor cable was out. The Captain called the pilot boat to lead them in but the anchor cable would not be pulled up as the motor was too weak to lift the weight of the chain. so they had to cut the chain and lost the anchor and chain. Lloyds gave permission for them to sail back after unloading and when they came back the ships engine was stripped down and a new crankshaft installed as it was bent, also replaced was the engine bed as that was also distorted.
