were you getting rattle in the timing chain area?
are you still with me Mark?
or did I lose you?
yes,its marked the inside of the case
Mark these primary tensioners are controlled by oil pressure. Generally when they fail it's because they are bleeding pressure off internally and cannot put sufficient tension on the main chain guide.
when this happens it usually results in a rattle because the guide rattles against the tensioner pintle because of the lack of pressure.
when we see a marked up timing case it's usually from the tensioner guide itself breaking at the top of the guide and if it doesn't fall to the bottom it gets trapped between the tensioner pintle and timing cover
the guide failures were due to issues in the guides and guide clips themselves. the part was later revised.
the primary tensioners themselves generally either leak internally or have sludge build up
let me know if you need anything else
if not be sure to leave a kind rating
Thanks for that Jake.We've had good oil pressure and we felt it was the ratchet which keeps the pin out which failed,what do you think?
the little ratchet or lever your talking about can be an issue if it manages to move positions because it will bleed out the tensioner
let me know if you need anything else please.
