45 Engine noise
I am led to believe that there is a 'problem' with a batch of 2.0i 16vengines produced late 1994/early
1995 ?
My XM estate (RP6744)has developed a noise similar to 'lazy tappet', but Ihave told that it is possibly
from the little end/piston, and that a replacement unit (@30,000miles!) may be necessary.
I have noticed several low mileage vehicles similar to mine for sale,and included in the description is
'replacement engine'.
Has anyone further information on this problem? ie cause (design defect I have heard?),engine
numbers for units in question, have 'Citroen' acknowledged they may have a problem?
======
This problem should only appear at cold start.
After 5 minutes this sound should be gone.The problem is pistons that are slightly too small.If the engine
warms up they extend and the sound is gone.
I know Citroën replaces the pistons and rings but there will be a moment that they stop this guarantee.
