hows this for a damaged head

and all caused as someone had dropped a rocker cover washer down the timing chain and never noticed it
that's whats left of it in sump pan, every inlet valve snapped and lying on top of pistons

Whose engine is this Bob? Any other damage to the rest of the engine?

Wow that some serious damage for just a washer

Not good but could of done huge damage to pistons and rods so if it's only head I'd say he's very lucky, seen an engine run with exhaust and inlet valve put the wrong way around lol

Surley if there is part of it in sump it will of caused more than just the head lads

Wow.
Thats what you was telling me about on the phone the other day.
Thats gutting for the lad!

Always remove all the washers and isolators before lifting the cover!

Did he not notice one missing when putting back together?

Geeze always have to be so careful when working on the car. It's easy to accidentally do something like this and not realise until it's too late.

Whats that tub of bolts and washers? Ah mate you always get that it will be fine lets start her up... clatter clatter caboooooooom. Oh maybe they were for something lolz

In all seriousness looks nasty. Glad he has taken it to you Bob and not continue on with th missery

He was trying to fix a leak and fit a rocker cover gasket then unknowingly dropped a washer when removing the cover, bolted it back up and found another washer to use on the stud that was missing one.

At that point if he had searched for the missing washer he would have found it sitting on top of crank sprocket but just carried on then cranked engine over to start it.
The washer will then lift the chain off the sprocket as engine is cranked then leave the seen damage (worst one I've ever seen)
The valve springs were all still up but engine was locking if turned over by hand which is why we never fitted new rockers and shims to try start it which is a good job in retrospect.
So removed the head etc and found this unholy mess lol

The amazing thing is that there does not appear to be any damage to the Pistons, rods or anything on the bottom end :scratch:and if you look at the valve seats even they appear to be undamaged so will remove the broken valves and see what the valve guides are like, if alls good then may get away with fitting new valves, seals and so forth, however the timing chain and tensioner will have to be replaced as no doubt the chain has stretched

Extremely lucky


It's a note to all doing what should be a simple job of removing rc
REMOVE THE WASHERS before lifting the thing off 

The other point is when you find a bit missing or left over make the effort find it, find what it for.
I dropped a bolt in a perkins diesel & no end of magneting could retrieve it so had to take few step backward in the rebuild to fish it out :-S
Happens to us all at times, just don't ignore the problem or above happens :-O lol
