#1: 1.4 hdi, air leak? Author: skinny, Location: HolbeachPosted: Mon Jul 02, 2012 3:10 pm ---- My 1.4 hdi sounds like its got an air leak
on tick over it sounds like a hissing noise or chuffing, sounds like its coming from under the air filter box.
any ideas what it could be?

thank you
but surely if its the injector seals it will be running rough?

remove the injector avoiding getting dirt down the hole.
there's a copper washer on the bottom of the injector - remove it and hold it over a flame (gas cooker} with a pair of plyers till its cherry red.
this softenes the washer. refit and tighten down. start the engine to make sure its worked then put it all together
