From memory, 2 teeth is about the absolute limit you can still get away with it (sometimes) on those v6.

Yep 2 x E14 for tensioner assembly

I think a belt tensioner / idler has let go on the Cambelt setup and slipped out of time

Summer is coming, if the belt has slipped and bent valves we could do an OOF top end overhaul on this for nostalgia sake


As it was during idle speed, I think the piston crowns will be fine, so damage limited to top end.

When the Cambelt failed on my 3.2 the pistons were fine - have driven it to Gibraltar and back since then!

Thanks for that Countrywoman - cheered me up no end!!
And yes, E14 is more like it.

I dropped a socket in the underpan and when I fished it out with a magnet two steel pins came up too. About 12mm long by 4mm in diameter. If they’d been there for any length of time they’d have dropped out. Could this be related to something?

I’m going to have a hard think about what to do next. My ambition may have exceeded my ability here…

Sounds like needle roller bearings------------

Yep.

I thought they might be locking pins to secure a gear to a shaft somewhere. Like a keyway but through the centre of the shaft. But there were only two.

Do the camshaft pulleys use locking pins like this?

dont jump to conclusions just yet . lets see what you find once the cover is off !

Don't knock yourself, you've done well to get this far.    At least get the cover off to see what let go. It'll bug you otherwise. 

[STEMO]

Did they look like these?

But you're on a forum of people who know these cars inside out, and will be wiling to roll up their sleeves - especially with the warmer weather coming

[Dave G]

The pins do look like those Stemo.
As I say, 12mm x 4mm diameter

[STEMO]

It's no use guessing, you're going to have to strip it down as far as the cambelt

[Dave G]

Here's those pins.

Oh Lord I hope this works, otherwise 40+ years of software development have just gone down the toilet...

Nope

cant think of anything in there that has a needle roller  bearing on it ??
the tensioner and guide bearings are ball bearings , as is the aux tensioner .
are we into the belt area yet and howz it look ?
