Engine knock
Hello all, I have searched everywhere for an answer to my V70 D5 knock 2006 car 135,000 miles. It has been there for two years but recently is getting worryingly loud.
Performance good and 43 mpg.
It is not the normal 'sewing machine' rattle / knock, but much slower on tick-over increasing with engine speed.
THE FIRST SECOND or two there is no knock. I have tried listen in oil filler cap, can't hear the knock there. Tried screwdriver in the ear to listen to injectors, nothing odd that I can hear. Any genius got any ideas ?. Thanks
