seriously loud knocking when engine speed increased is it possibly an injector
What is your question?
Hi all my son inlaw has a 350 e61 diesel and recently got me to check out a tapping noise coming from his engine. It turned out to be swirl flaps had broken I removed all of the offending parts and fitted blanking plates. All was going well for a few more thousnd miles until yesterday when he developed a loud knocking noise on the way home. He called out recovery AA. who told him one of his injectors is leaking.
Is this common to make such a loud knocking noise I have heard (diesel knock) but never this loud. the noise is only present when the engine speed is increased,plus there is a missfire while its ticking over.
ps the drop down box at the top of this page doesn't give the option of a diesel derivative.

unfortunately I have now stripped the engine down and am about to remove the cams and head so I can't run the engine you may be able to help aswell is it necessary to use a cam fixing tool to remove the head or is there another way around this I don't want to have to buy unnecessary tools that I will only use just the once. I am skilled but recently redundant tech so I have all tools (snap-on) but not specialist tools
