Hi Guys,
Got a weird one, I installed an EGR blank plate into the intake side of my ZD30 the other day.
I was very impressed with how the engine ran after installation, much more responsive and smoother. However I noticed under load in 3rd and 4th gear at 2500-3000 RPM a loud tapping sound seemed to be coming from the engine (sounded like a loud tappet-ish noise).
I removed the blank plate and tested again, the noise was gone.
Anyone know what this might be, I'd obviously like to have the plate in to keep the engine clean but the noise was quite concerning.
Cheers in advance.
