Noisy Engine

[Ibesty2205]

I have a fiesta 1.6 st mk7.5, only done 40000 miles. Ive owned it for 5 years. I leave it for half an hour or overnight once started it sounds like crap! It's tapping it's nuts off(alot more than it should) i also get a noise from the bottom of the engine behind the drivers side wheel like an exhaust blow. It goes after about 3mins, I have had it in a garage they can't find the issue. Any ideas would be appreciated cos it's doing my head in. I will upload a video as soon as I can.

If the tapping noise goes away after warmup, I'd suspect it's lifter tick and possibly your lifters aren't pumping up very quickly. Perhaps you have some oil sludging.
