Towed the neighbours Corsa D 1.0 back from a rip off RAC approved outfit.
They charged 78 quid and diagnosed timing chain had snapped.
Pulled the rocker cover and the chain is fine, however a lifter has failed, rocker has punched a hole in the cylinder head, fragments have jammed the exhaust cam, and the chain sprocket bolt has sheered.
There is no oil on the dipstick at all
Was that the cause of the failure.. or... the aftermath.
I would guess cause, its recently been serviced by a 'trusted' garage and the filler cap has one of the locking tabs broken and was a loose fit, loads of oil down the side of the block on no 3 cylinder.
When these run low on oil the followers pump down, release the rocker and it makes its way around the cam casing (or through it in this case)
I suspect the rocker has then locked the cam, sheared the cam shaft to sprocket bolt and the valves then mated with the pistons
