I am in a dilemma over the best route forward regarding problems with my Ford 1600 diesel engine.
Last season, I had a problem when the engine started to make a horrendous knocking noise which was traced to one of the injectors having a small piece of steel stuck in it. The thought was that it may have been debris from the high pressure fuel lines so these were cleaned by blasting the insides with a connection to a pressure washer and dried with some acetone.
The engine ran perfectly for about 20 hours but just as we were getting the boat pulled out for the winter, the knocking noise came back indicating yet another injector misfiring.
Latest advice I have been given is that it may be the CAV DPA pump breaking up, one theory being the “bearing” starting to fail.
I have two alternatives thses being to get my existing pump stripped, the alternative being to get my spare DPA pump checked which was bought on Ebay as being fully serviced! but was it?
The advantage of using my existing pump is that it can go direct back on timing marks but apparently, a new pump will require the timing to be reset. Advantage of getting my (possibly) fully serviced pump checked is that it should only require the seals changed as it has been lying in the garage of about 7 years.
Any thoughts or shared experience with CAV DPA Pumps.

Apr 12, 2011 I have a CAV injector pump on my Massey Ferguson 235 a DPA 3233F360. I rebuilt a rebuild job where the previous mechanic did not replace the crank, oil pump or water pump. He undoubtably timed the engine according to his 'back yard' way of timing. The engine will run with starter fluid but I am having trouble getting the injector pump timed. Fortunately there is another method called “spill cut off point timing” which we can use to time the injection pump.

Next, remove the clips at the brackets on the injection lines closer to the injectors. Loosen all of the injection connections at the injectors. Do not remove the lines. You can remove the water crossover tube if it is in your way, but drain about a 1/2 gallon of coolant before your remove the crossover. Remove the oil fill tube from the timing.
