Just thought I'd share the story of my day!
My little bro bought a Rover 214 convertible about 6 months back (yes, I've already told him he's a prat!).
It conked out completely last week and he was told by the AA that it was the head gasket, so he and my dad (a car expert but 30 years ago) started to take it to bits... After an hour or so I got the call...
Got there today to find the camshaft cover removed, along with manifolds and part of the cambelt cover. Was shown a completely melted engine cover, a wrecked HT lead and a spark plug with the top contact completely melted!
This car must have SERIOUSLY overheated, as the engine-side of the cambelt cover has also completely melted to the cylinder head and has solidified to pretty much encase the front camshaft sprocket.
I've had the whole lot to bits, removed the head and found that one of the outlet valves on cylinder 1 has been bent and jammed open. Also there's a nice dent in the top of the piston where it has clearly impacted. Seeing as I'd already decided the head was a write off, I thought I'd bash it a bit and managed to get the dodgy valve moving. It now closes, but isn't a perfect fit.
Thought I'd put the lot back together for the hell of it, to find out if it runs. Normally I'd put a new cambelt on (but not wasting £40 on the kit if it's dead anyway) and would get a new cambelt cover (again, ditto).
In short, I've freed the damaged valve, replaced the head gasket and re-aligned the shafts (we're fairly sure the camshafts were out by a tooth or two). Tomorrow is moment of truth when we re-fit the manifolds and fire her up.
Anyone care to take a guess as to whether it will run in a driveable way?
Or does anyone know how the hell it could overheat in such an insane way?! My guess at the moment is that the jammed valve caused cylinder 1 to run hot (as it looks like it's overheated most) and the water leak from the gasket did the rest.
Anyone got any tips for me? First time I've done the timing on a dual-cam engine, got the garage to do my Vec last time. Was a great learning experience to be able to faff with a car and not worry about damaging it!
