Clicking sound when driving, like a rattle from the engine is sounds really loud. Just had it serviced and correct oil has been used any ideas for fixing for sti 5

 

You havent got frankie howerd in the boot have you

 

come on be serious I am worried

 

Did it do it before the service? Does it do it at specific RPMs, or throughout the rev range? Does it do it floored, part throttle, or both? Does it do it in specific gears, or all? Can you pinpoint roughly which area of the engine bay it's coming from...?

 

Check your heat shield. If one of the securing bolts is loose/aftermarket decat downpipe fitted then you will get the rattle you describe, especially noticable when idleing. Fixed by using a new bolt with a decent sized washer as a spacer and plenty of WD 40! Failing this it could be further down the exhaust at one of the brackets.
