850 T5: Possible sticking valve lifter

    I'm (still) having trouble with starting my car requiring lots of turnover
    (10-20 secs) at times.
    It's been suggested that this may be due to a sticking tappet which keeps
    the valve slightly
    open at rest thus given no compression. If so, could this just be a single
    valve? Would it
    not at least attempt to fire on the remaining 4 cylinders?

    What's solution - is there any additive I could use? Very thin synthetic
    oil?
    Head strip down?....

    Any advice gratefully received!

    How about measuring the compresion ratio, that should indicate if you got a
    problem with at sticky valve.

    Yes, good idea.

    Ps. Unless it starts doing it intermittingly then it's be a pain I guess -
    but all I can do!
