Hi all,
Something that has been happening a while but its bugging me now. I believe its only on cold starts, soon as the car fires for around 5-8 seconds there is a single loud tapping noise which eventually disappears and doesn't seem to come back until next time.
The car sounds tappety but i've always put that down to the injectors even being swapped twice.
Could one or more of the hydraulic lifters be on the way out? engine has only done 93k and was regularly serviced.
