Maybe if you used some long spacers and washers, by putting the head bolts back in situ, you could "imitate" the head being on and free the crank up?

And try bashing the end of the crankshaft, that may free it up, or insert a small crowbar between the balance weights and main bearings castings and try to move (free up) the crankshaft slightly that way..

just a thought, but are you putting that angle iron in place then trying to turn the engine, I don't mean to insult your knowledge but I have had a lot of strange answers before.

superdavid, yes the angle-iron is in place to secure the liners from being disturbed when the pistons push up. The pistons don't rise as high as the angle-iron so are not obstructed by it

For those still interested in this topic, I went to the garage yesterday and saw a 1.8T with manual gearbox stripped down similar to my own. The mechanic, who was very helpful, showed me the crankshaft turning freely with no bother. I phoned Haynes Technical Helpline this morning and asked them why they advised in their manuals that the crankshaft is difficult if not impossible to move after the head is removed. Their reply is that the block warps when the bolts are removed and the solution is, as feared, to temporarily re-fit the head. So here goes, I'll let you know how I get on

i meant the bit locking the fly wheel.

Must admit have worked on 20+ K series engine over the years and never had a problem turning the enigne by hand, (2 bair never had to lock the liners in place either, only ever found one liner that moved. Will be interested to hear how you get on with this.

Yep, that did it. Refitted the head temporarily, didn't even have to torque it up just wrench tight and bingo crankshaft rotates freely. The damaged piston is removed now, looking forward to the fun of replacing the gudgeon pin for the new piston, Oh what entertainment!! Thanks to all that answered.

Default Crankshaft turning

Gudgeon pin should not be a big problem,I usually use a bolt and a socket to pull it out.Bolt goes throught the socket and you pull the pin into the socket.
Hope you understand my explanation

Thumbs up

In the old days we use to put the piston in a bucket of boiling water when it was hot the gudeon pin would push out, push the new one in and then let it cool Bingo
