Intermittent rattle from engine. 159 TBI.
I have a 159SW TBI and today I noticed an intermittent rattle coming from the engine. I would describe the rattle as sounding like something being rattled inside a can.
The rattle comes and goes every few minutes or so. The frequency of the rattle increases with engine revs, rather then the speed of the car and when I can hear it, it lasts for about 20-30 seconds and then goes quiet again. It will then come back again a few minutes later.
Other than the rattle the car seems to be be performing as normal.
The car has recently been into the garage to replace an air con pipe (last week). The description on the receipt mentions the following "Remove under tray, induction hose and turbo hose to access air conditioning pipes from compressor to condensor."
Could the two be related? Any suggestions or ideas?
