Loud rattle after modding the plunger
Posted: Sat Sep 14, 2013 3:12 pm
Hello to everyone
I have registered because I am desperately looking for some help. I am an owner of 1.6TD SB engine. Generally my car is under rebuilt so I am not driving it right now, however, I add bits and pieces and not that long ago I modified my pump. Namely, the pump was given TDI 1Z 10 mm plunger, I left oem cam plate. The engine got new Bosh SB injectors (DNOSD297), set to 155 bar. Timing mod and gov mod was also done.....
The problem is.... after starting the engine, I get the rattling sound which I can't get rid of

I have checked two sets of SB injectors (borrowed from my friend), the same..... I also managed to borrow KCA27S77 AAZ double spring injectors and although they made the engine softer.... I still can't get rid of rattling...
I also did experiments with delivery valves, I used SB and TDI ones and finally decided to stick to TDI ones because they make the engine work softer....
Any ideas on my problem?
According to people who modified their pumps using the same components, everything should be ok...
