Engine rattle when cold
My V70 with the Audi lump has only covered 66,000 from new: regularly serviced. It suddenly developed a rattle when cold - quite loud - which disappears within 5-10 minutes, and does not recur until good and cold again. It also goes away with higher revs, but comes back around 1500 revs - until warm, when it vanishes completely.
The independent garage I use is convinced it's external (ie not within the block): they've used a stethoscope to try and track it down. So far they've replaced cambelt and tensioner, but the noise is still there, although it seems to go off even sooner now. They've established that it's not caused by anything driven by the ancillary belt (the one outside the timing belt cover, that drives the aircon compressor amongst other things), by running the car cold with that belt removed - noise still there. They say the water pump is fine.
They want to replace the crankshaft pulley now - sounds expensive to me!
Anyone any experience of this?
