Mk4 1.5 noisy tappets??

[Jay035]

Mk4 1.5 ecoboost in auto 

Has anyone notice clicky/tappy noise from engine between 2500rpm to about 3500rpm? Gets faster as I rev or drive spirtitedly 

Is this normal? Someone mentioned its the high pressure fuel system

It's the injectors opening and closing

Cool it's rather noisy definitely reminds me of tappet noise on older engines maybe it's the design and characteristic of ford engines

It is just a characteristic of a direct injected petrol engine. Basically every direct injected petrol engine has this. Most direct injected petrol engines have a sound insulated cover to reduce the noise of the fuel injectors.

Thanks guys I learn something new everyday. I'm starting to show my age

It’s probably more noticeable as it’s also got port injectors so it’s really quiet at idle, compared to previous ecoboosts with only DI that are noisy all the time. 

[Jay035]

Ahh i see, because the mk4 is port and DI does build carbon on the injectors like the DI only engines? 

[alexp999]

It shouldn't do, at least not as much.

Il refrain from adding a catch can at this point il use a boroscope once it's done some miles
