andy james Posted August 30, 2020 Posted August 30, 2020 I know this subject has been covered on this forum and in the US but I’m pulling my hair out as to why after storing the car over the winter she suddenly developed a loud ticking noise which seems to be coming from the top of the engine. Using my stethoscope the noise seems to be on or around the fuel rail. Research points to 4 common faults and I have checked, cleaned or replaced all of them. 1. Fuel rail damper. Replaced. 2. Fuel damper from tank to fuel rail. Replaced. 3. Injectors removed and cleaned on the bench with carb cleaner pushed through while connected to 12v supply. 4. The most obvious culprit and the worst case scenario was a worn bucket lifter. I removed both rocker covers and checked the camshafts clearances and are all fine. As my car is not stock and has bigger injectors, a fuel return system I’m struggling to think a knackered injector can make such a loud noise! Any ideas would be appreciated. This is a video of my Z diesel! Quote
ThreeFiddyZ Posted August 30, 2020 Posted August 30, 2020 (edited) I had a ticking noise on my 2007 DE Rev-up, that was fairly similar. Check out my YouTube video - I had some success in switching to a 5W - 40 oil, instead of 5W - 30. I also replaced my Fuel Damper, but that made no difference.

andy james Posted August 31, 2020 Author Posted August 31, 2020 Tried 5/40 oil, seafoam in the fuel etc. Running out of ideas. Many have said just drive it and whatever it is may free off! Putting her back together tomorrow. Quote
350z mike Posted October 19, 2021 Posted October 19, 2021 Hi bud, did you find out what was the cause of your engine tick? Mine does the same but from cold start, once warmed up after a few minutes it disappears. Did/does your car tick all the time or just like mine from cold? Cheers 😊 Quote
Ebized Posted October 20, 2021 Posted October 20, 2021 (edited) Maybe an Injector - seeing what Alex says (2nd post down) given you have done the fuel damper check: Edited October 20, 2021 by Ebized Quote
andy james Posted October 20, 2021 Author Posted October 20, 2021 I’m afraid my tick was a terminal one. Piston broke off by the gudgeon pin which in turn damaged the cylinder beyond repair.Had to have a very expensive forged engine rebuild. 3 Quote
