    Serious and Expensive

    My 1976 SWB Series 3 which I have owned for 11 years always had a little rattle under load. Last week driving along in second just leaving home the Landy died and would not start. When I towed it home I could not crank over the engine. Serious and expensive?
    Any ideas.

    Ppossibly, but can't tell until head and sump come off. Petrol or diesel?

    I take it there is nothing obvious like a conrod sticking out the side of the block?

    On the other hand, it could be a simple electrical failure - can the engine be turned by hand? If it can't be turned by hand, it is probably serious and expensive, if it can, probably not. (Could not crank over for some people means starter would not turn it, for others means crank handle wouldn't)

    The rattle may have nothing to do with the stoppage, but then it may.

    I tried it with shifter, canít use a crank handle because the shorty is fitted with a pto winch. The original 4cyl petrol engine appears to be ceased.

    Well, it has certainly ceased running, and sounds as if it has seized.

    There are a number of possilbe scenarios that can resullt in this, none of them particularly comforting.

    Off the top of my head, perhaps the most likely is either overheating or loss of oil pressure has resulted in either a crankshaft bearing or a piston seizing. If this is the case, there may not be a lot of serious damage, but it still means an engine strip down and recondition.

    The worst is possibly a major failure such as a lost connecting rod cap or a broken crankshaft, that has caused major secondary damage to the block. In this case - look for a replacement engine.

    Another possibility, suggested by the pre-existing rattle, is that the timing chain has broken and jammed the crankshaft sprocket. In this case, there may belittle secondary damage.

    There is a slight possibility, if you tried to restart the engine, that the engine stopped for an unrelated reason, but when attempting to restart the starter has jammed in mesh - in this situation the engine will appear seized. If this is the case, the problem is not serious. Check for this by loosening the starter - if this is the issue the motor should then be able to be turned slightly, and you can remove the starter, ensure the bendix is working freely, reinstall it and carry on from there, having made sure the engine can be turned while the starter is off.

    Have you checked the oil and coolant levels? These might give a clue. Draining the oil and checking for lumps of metal is another source of information, followed by removing the sump and looking at the situation. (Head next)

    Thanks for your suggestions John I will look into the starter, it was replaced about 10 months ago with one from a 2a. I was told that these were more reliable. Hope it is not totally seized

    Update....
    Valve cover removed white sludge evident.
    Removed spark plugs and inspected piston tops with camera, found no abnormal signs of wear or anything blocked. Some carbon build up on pistons.
    Removed starter motor, engine still will not move.
    Drained and removed sump. Oil sludge in sump and some very small metal filings on top of sump baffle, but no water present.
    Checked timing chain for movement and it moves slightly both ways only on chain slack.
    Checked connecting rod movement on crankshaft, all have plenty of thrust clearance suggesting piston bearing are not stuck.
    Removed front crankshaft caps except rear. The bearings looked worn but in ok condition.
    Rear bearing cap was not removed as engine still connected to gearbox.

    Could be rearmost bearing has stuck/slid in bearing cap.
    Looks like engine will need to come out.

    The sludge is it white .that would show you are getting water into the sump, if it is black or grey colour that would be normal age sludge.

    Just wondering if the problem isn't in the timing cover , broken chain , guides or tension-er, that could explain the rattle.?

    The other thing would be if something has gone wrong in the clutch or gear box .

    Mayonnaise in the rocker cover was common in the UK in winter months
    Mainly caused by short journeys, condensation emulsifies with the oil.
