    Well it’s not been a great start.
    My LWB first registered in 1992 is in a sad state, much to my embarrassment and chagrin. I built it over a 4 year period and had it roadworthy just in time for our wedding. I then ran it as my main car for 8 or 9 years. A new house, children and life took over and the marlin was left alone for far too long. .....

    After putting it off for more than 3 years, today I finally lifted the covers and lid on my roadster. Aside from the obvious deterioration of all the soft and flexible bits, the engine has seized and no amount of “encouragement” to turn it over manually has worked.

    So the medium refurbishment i anticipated is now a really major refurbishment / rebuild with either; engine rebuild, replacement engine like for like or a new power plant with all the associated extra work that would entail. Phew...!

    Many deep breaths and a large glass of wine later I am slightly more sanguine but still deflated.

    Hopefully my next post will be more up beat

    Hi Mikeyp,
    Take the spark plugs out and squirt a bit of diesel in the bores then leave to soak for a day or so then try turning over by hand with the plugs still removed. Sorry if you have already tried this.
    Keep us posted with pictures please and good luck.
    Cheers, Martin.

    Patience is a virtue, 24 hrs after being seized for a year or more is nothing.

    Putting diesel down the bores will quickly end up in the sump , to slow that down try mixing with some red automatic transmission fluid. Hopefully the Auto transmission oil will get to sit around the ring surface. With the plugs removed place in 4th gear and gently rock it back and forth.
    If you get it to move the tiniest bit then add more oil mix to the bores to prevent piston ring breakage when trying for a complete revolution.

    Apparently distilled vinegar or coke(not diet) may also help free off the rings, so they would be my plan "B"

    Before I acquired it my Roadster had sat for ten years outside under a tarp with no rocker box, accumulating water in the sump and more interesting in the inlet manifolds. It took over a year to get it running properly as a rolling restoration. Keep the faith and patience, don't be afraid to walk away and come back tomorrow if it is not going right. Good luck!
