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!

Graham

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

Yes, good idea.

Graham

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