    Default Massive overheating, bent valve, head gasket gone, what would you do on a 1995 Rover?!

    Hi guys,

    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!

    If its got that hot, you need to reface the head. Even when i have done these before with the modified head gasket, they come back six months later. So i put K seal in them now for good measure and they seem OK.
    Personally i think you have wasted your time as its got so hot, second hand engine would have been better.
    The head has probably bowed that much that's why the valve got jammed.

    I have to say it will probably have warped the head and the best course of action will be replace the entire lump.

    I would have to question how it is possible to let this happen as that sort of heat would take quite a time to generate so once the car started to run rough it must have been kept going for a few minutes or more to get to that mess?

    From what I remember of these engines, they were good for the head gasket going in the front right hand corner. I recon it would be a good idea to get the head skimmed too if you are going to do the job properly. I belive the new head gasket is thicker than the older" one too.

    Sounds like a woman driver has driven it to destruction

    I would have thrown it away before it overheated!

    The older rover is notorious for cooking , and not really repairable to a satisfactory standard.

    Well the lesson is you bought the wrong car. They do some head gaskets which help take up warping in the head. They are designed for Porshse's which have terribel overheating problems as well but maybe you can get the matierial and make one for your rover? Think yourself lucky, they generally score the bores on porshse's as well.... lol

    Nah best bet is a new car, you are only throwing good money after bad. As has been said once the head is warped it leads to even more problems as there will be more faults that are not immediately visible to the eye, but will become obvious once the engine is running. I would have thought with what you have described that almost everything will have been affected if the heat was that bad.
