944_S_TYPE

Hi Guys/Gals, I am not too sure if this has been done before. But to all of those who have had a chain tensioner fail, Or know someone who has (who will not post here) Which part on the tensioner failed?

Photo "borrowed" from rennlister joseph mitro.

the gift that keeps on giving. i've seen that photo about 13 times now. ::

for me, the pad failed, essentially ripping everything off with it.

I've always heard of the top pad itself crumbling and slipping off the tensioner, allowing the chain to lock up on it.

that's exactly what happened to me

edit - man, that's been exactly two years ago!!

Ditto here

Sorry you learned the hard way. First thing I did when I bought my S2 was replace the entire tensioner assembly.

Good peace of mind for the past 6 years.

Anyone else?

Replaced mine before it failed . Saw those horror pictures and got proactive !

Mine didn't fail, but the top pad was definitely a lot more worn than the bottom one.

My head has indications of repair so it happend to the PO. I have no idea how it failed.

no failure at 110K miles....can't say the same for the rod bearing

Are S2's any less prone to this?

My old tensioner is a paper weight on my desk, thankfully it's in one piece and so is it's replacement.

Car's only done 52K miles though.

Adding to car_slave : do 928's let go as well?

Top pad failure here also.

you can add one here for us on seans S2 cab, The top pad failed then the whole assembly came apart....BOOM! took out the intake cam teeth and the head Broke the tensioner mounting lugs off the head, my 968 was also missing a few teeth on the intake cam but the head was still serviceable
