I know there is oceans of expertise here and Ive spent last few hours seeing if I could find an answer to my question (and help I need) on previously answered questions.

Ive to take the head off my Ski (broken plug that wont come out with usual eg easy out, heat etc)

I dont have a hoist and was wondering if I can lift and reinstall head leaving engine in Ski? If so, is this much more difficult because engine is in (no real choice for me).

If it can be done with engine in, could someone please give me some advice on locking the timing end of things please

Thanks a million
