    Engine drop

    Getting there, managed to squeeze time to drop engine / transmission today. Next I will perform a leak down teast (cold though) just for the fun to see where it leaks per each cylinder. After that I'll separate the head.

    PS. Is there any way to increase my attachments limit, it seems very low and I hate to upload low resolution pics especially when we get inside the engine..

    Any ideas where to purchase a good repair manual for Smart 452 engine? That would speed things up esp. when putting it back together.

    It seems that Alldatadiy contains information only for ForTwo's. Does anyone know if the manual in emanualonline is of any good?

    Got some time today to get rid of intake parts and prep for separation of tranny and engine. Before I got forward I noticed that turbo does not turn a bit. Then I noticed it was totally jammed and after some more inspecting I could extract one part of the turbo blades. Not good news, I guess these aluminum parts got inside intake and ruined piston rings and most likely some more.. Have to separate the head and see what else is there and is this engine repairable or not.

    Fuct rings and '17.5, 15.8 and 17 bars' compression pressure?

    Reading the plugs and an endoscope would be a sight less work - and achieve the same.

    Abnormal (higher) than normal compression results become because the cylinders are soaked with oil. Oil is giving false positive results.

    Agreed, my smaller scope is broken and my larger one does not fit inside the cyls. I've managed to inspect valves and cylinder linings before with a scope and mirror quite well. Will check if I can quickly buy a scope somewhere.
