ooch, that does not look good.

I hope there is not too much damage.

Have the cam sprocket bolts let go John

Tough mate, hope it's not to bad.

Hi John, that's very upsetting, any warning noises ? Fingers crossed it's not too destructive. Martin.

Not a pretty sight John. Hope it looks worse than it is.

Ouch, does look like the bolts have sheared. Hope it has only bent the valves and done no more damage.

I once developed a nasty top end rattle taking the car for its MOT (can't remember which one) on examination the bolts had both come loose despite the lock tabs being in place. The only thing I could think of that may have caused it was the 6 month winter layup and maybe something in the valve gear had seized overloading the bolts on startup. New bolts and locktab cured it, never leave them all winter now.

Still no idea of the extent of damage.
So far I've just found the RH timing chain derailed top and bottom and now tight as a drum about the sprocket hubs. Managed to recover the tensioner and spring using one of those extending magnet probes, at least these didn't make it down into the sump. Unlike the missing sprocket screw, or rather its sheared head, note the tab washer with the tabs folded up. The screw has sheared head side of the sprocket, the other one whilst still in place, was finger tight and had semi-flattened the locking tabs. Could the screw head have sheared through fatigue, as one or both of the screws had worked lose, allowing the sprocket to flutter. I've posted here recently that I've noted a top end 'tappet' noise and wondered what the likely cause was, it could have been the sprocket seating back in place every 180 deg. until the point of no return was reached. I guess I'll find out shortly.

that looks familiar..... hope the damage is relatively minor

[Mike J]

Wrong time of year for that to happen. I'm near Bromyard if I can be of any help. Have engine hoist if it helps. What should we all be checking to prevent this happening?

Best of luck John hope for a speedy recovery please keep us posted with pictures of what you find

Take the cam covers off and check the sprocket bolts. Good luck with the repair I hope the damage is minimal. Graham

Hi Graham,

Is that Canarian air getting to you, or have you been on the sherberts ? John reported his detailed findings, after having done just what you suggested.................2 1/2 hours BEFORE your post
