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.

CAV DPA/DPS Fuel Injection Pump Timing Correct timing of the Lucas CAV DPA/DPS fuel injection pump can be verified by removing the inspection plate. Filename: 2010-514btFuelPumpTimingMARKS.pdf - Read File Online - Report Abuse. To verify that the fuel injection pump is timed correctly, first check the alignment marks on the pump flange and gear housing. NOTE: 1 mm of rotation past the timing mark will advance or retard (depending on direction of rotation) the pump timing by 1 degree. The Lucas CAV DPA, DPS, Delphi DP210, Stanadyne DB4, and the Bosch® VE fuel injection. Cav Dpa Timing Marks Off. History is lacking.I would appreciate any information on the timing mark on the CAV pump that may help me save some work in pulling the.
