This is the first time I have had a chance to post this information.
As all are aware i rebuilt the 892"s in my 52c to the tune of about 70.000 "just shy" that number. It was not a Palm Beach rebuild new heads.water pumps, turbos were all sent off and tested and repaired, pistons sleeves. crank is all that stayed. Western branch did the rebuild I used them rather than a man in a van. I wanted a good job and if anything went wrong the company is big enough to back up the warranty i requested in writing. Well there were problems with smoke from the sea trial on. After about 2 years of trial and error and test after test after test. It boiled down to injectors.The injectors were taken off and bench tested. Out of 16, 13 were not good they were not spraying or creating a fog. They were as the guys said peeing a stream.After replacing only the bad ones some of the new ones were bad and 2 of the old went bad. This procedure went on and own for 2 years. A total of 42 injectors were put in. I took all the injectors out and put them in a box and dumped them on the service managers desk. (by this time i was ill) I took a pick of them and sent it to the owners with a well worded note from my legal adviser. In the mean time i purchased new ones from Bosh. The engines run grate now. No smoke at all. I will add that getting the correct injectors was a task. I did not realize that there were many many injector numbers for the same engine.
WHAT I AM TRYING TO SAY IS DD INJECTORS ARE CRAP................ This is based on first hand experience. If you have smoke or at least haze off in the distance you may want to bench test the injectors.It was suggested not to mix name brands,why i do not know.I do understand now this problems is nation wide. Western Branch being a DD dealer would not admit there was a problem.The young girl in the parts dept spilled the beans.
