Yeah creaking away like mad - the jet wash seemed to sort it out when it first occured a couple of months ago, but back with avengeance now! Thump is ocassional and most noticeable over certain bumps in road, others there is nothing!
Got my V8 LPG'd a few months back - Easy hassle free conversion and makes it seem a fairly sensible choice now

More economical than a derv :tease:
Drove it standard for 6 months or so, until I was sure that it was the motor for me - then booked it in.
