    Default 807 carnage

    I ended up with a 807 which I knew had been sitting, but turned over and got stuck. So why not take the punt. Turns out, it had been sitting for, well...

    Oh... and yes, we had dust come out of it.

    https://photos.app.goo.gl/VFEPgSafMoUifKo96 (Yep, all 4 are rusted to the liners. The small end moves if you smack it with a large hammer.. )
    https://photos.app.goo.gl/EQk45WkRaZrNL6EJA (I hadn't realised the valve gear doubled as the head studs. nice)
    https://photos.app.goo.gl/mmsuDXBYoeFK7Mzu7 (kinda pretty really)

    Anyway this is way beyond me, and I don't really care about it being "authentic" . A quick run of the calculator shows 2k worth of stuff and then it will still be a 40yr old 100hp engine.

    Perhaps there is some stuff one needs? Covers plates, coolant sensor?

    No but seriously the manifolds, rocker cover, sump, carbi, front chain plate etc etc look fine. I suppose the rocker gear will clean up? The pushrods looks like tent pegs found by the mower. Could you trust the rest of the gear?

    The crank actually looks ago. (I'll take some photos in the morning) The cam looks pretty bad, rust, pits and marks everywhere. Oh! the oil pump drive cog in the block is missing some teeth. Did they tend to do that?

    This forum suggests the block is also salvageable. It's way beyond me so if you want / need any of this stuff let me know.

    I'm out a little bit of coin on this and would appreciate your charity

    or just a hug.

    That would be one of the worse 807 engines I have seen, looks like it has been stored outside in the weather.

    Having said that, with a bit of time and patience a lot of it will clean up.

    I have an 807 engine stored in the shed and had a bit of a roof leak before I re-roofed the shed and some water got into the engine and seized it, I managed to dismantle the engine and clean and reuse most of the major parts.

    I was impressed by the various high tide marks on the block. The seasons are transferred into the aluminium.

    807's

    Natural forces mark their passage,
    Their journey described in irons so bright!
    Wanting for their brothers return,
    Water gives live, and patiently waits for all to answer.

    Looks to me like that engine needs to marinate submerged in a tank of diesel + brake fluid for a few months.

    The corrosion in the block is not as bad as some I have saved. I could be interested in the head if it is not too thin and maybe the rocker shafts and rods.

    I'm going to spend some time with a few more L's of degreaser and a wire wheel, I'll keep you updated.

    Don't.

    Use a solution of vinegar and salt or hydrochloric acid see youtube for rust removal (steel bits). Or caustic soda if you like (not for aluminium). Leave for a while and all healthy metal will be revealed. You need to oil it immediately after that because it will flash rust in seconds.

    I seem to remember somebody offered you a good engine for free.

    The block doesn't look that bad. Might be worth a clean, that looks like rust coming off the liners, not aluminium corrosion. Not sure what solution to use.

    Oh that's right, it got lost in the moving to Sydney / getting married stuffs.

    Bugger.

    Ah sorry yes, commend about wire wheel in relation to rocker gear that looks like a treasure from the Titanic.

    I've got the block soaking in a thick mixture of CT18 truckwash. I'll smack it with bristles and water tomorrow then swap the head in over night.

    What happened to your 807?

    Making up a bath of diluted molasses is also highly spoken of - but away from the house and/or close neighbours.

    #Carnage update

    Well it's looking a little more like parts of an engine;

    https://photos.app.goo.gl/p5zriqvDQg5y3Gpx5
    https://photos.app.goo.gl/YMa8LAn5X7EddYco8

    This is the result of soaking it overnight and attacking it with a brush filled with bristles. The material was lifted from the easy to reach places, I'll plan for a gentle scratch pad and try to get into the other areas, so far so good.

    Similarly with the head most of the "rust" was able to be scrubbed away, The valves / lifters still wont move, I'll soak those sections in WD40 and try again in a week. I'm assuming I'll have to punch these lifters out, just find something that fits on the head and smack away?

    And I managed to get the valve train apart. It took 2x batteries with the wire wheel, only then where things starting to free up. It looks as if the shaft is "ok" more scrubbing and fresher eyes to look at it all a bit closer on the weekend.

    Nah, don't hammer things. Soak, clean, soak, clean. My guess is the followers are cactus, i.e. rusted in the holes. If you hammer them out, you will destroy the bores, which are precision machined hence ruining the head. You won't be able to use the tappets, but the head is valuable.

    You got a nice clean block there, no corrosion in the liner seats and nothing significant elsewhere. Hang on to it. If you can take it to be professionally cleaned (steam blasted?) it will come up like new, then an appointment with a surface plate will tell you what you can do with it. Do you want to buy a nice Mitutoyo bore gauge?

    The list of parts that you will need to rebuild this motor.

    Piston liner kit
    Big end bearings
    Main bearings
    Lifters
    Inlet valves
    Exhaust Valves
    Valve guides
    Full gasket set
    Rear seal
    Front seal
    Timing chain
    Spark plugs

    The rest will probably clean up ok and can be re-used

    Another thing that you will need is a Renault R15/17 manual for the engine section and also any other R15/17 parts you decide to bolt on
    vivid and bowie like this.

    The parts are not the expensive bit. You get into head machining, block machining, crank and so on, it builds up quickly. A head done by a respectable place here in WA cost me 850. That includes everything you can ask for a head.

    Another area that needs consideration is the oil pump, both the block/cover castings and the rotor. The rotor and cover can be replaced easily, but the block casting needs to be perfect to give a respectable pressure. If any machining is needed there, you will have to find a rather schmick shop to do it or the block is scrap. And if you find a good shop, they won't be cheap. A dry sump setup might look like a cheaper alternative then.
