Re: 4ksq Noise after timing belt and water pump replaced

[Mark Eissler <marke@bigendian.com>]

Hmm. I've had this problem for 6 or 8 months now. Or about 20,000km. It
has yet to go away. On my 4k, it only makes a wheezing sound at a certain
RPM and a bit at idle. Is the "howling" sound (that everyone else is
describing) present at all engine speeds?
