Tappet / tapping / fluttering sound - 1.0 Ecoboost
I've had a look through similar topics, but can't seem to find any definitive answers.
I have what sounds like a tappety / fluttering sound from a 62 plate 1.0 Ecoboost.
The sound is particularly noticeable from a cold start for around 10 minutes, until the engine is up to temperature. It's only only noticeable under acceleration, and stops as soon as I take my foot off the accelerator. It isn't particularly noticeable at idle.
Oil level seems fine, I've used a tin of Wynn's hydraulic valve lifter treatment but to no avail.
