oh very good ! excellent . Your crank locking pin behind the starter .. when fitted does the mark also line up on the lower cambelt sprocket with the line in the alloy cover ? the volvo locking pin isnt round on the end , it is shaped so may not locate the crankshaft in the same place as yours, in other words your tool may not lock the crank in the correct position in which case you would be better off lining up the marks on the lower pulley by eye ..

It does Clan, yes.

What a difference the locking tool makes to getting the crank nut off!
I was expecting it to go with an almighty crack when it came free , but no drama at all . I actually thought that the socket extension must be shearing or something ,but it was just the nut turning.

With the engine now timed properly , it still sounds rough and is still smokey.
Guess the head will be coming off now then .

Did you try compression testing cylinders,this should show definitively if the valves are damaged as they will not close properly.

I didn't bud, as I don't have a gauge .
Im not sure that it can really be anything else though ,so probably not worth bothering tbh

As the valves are vertical in the combustion chamber they tend not to bend when hit by the piston , they get pushed straight up which puts a big load on the camshaft and rockers , this breaks the bearing caps which are frail and designed to do this to absorb the huge forces , also the rockers between camshaft and valve stem take a huge blow which distorts them and they bend or break which also puts a side load on the actual hydraulic tappet and this breaks the bore in the head which the tappet fits into writing off the head , the pistons etc below usualy escape any serious damage .

Someone mentioned to me today something about the diesel pump may be out of timing .
I confess , I dont have a clue what they are on about (no mention of this in Haynes manual).
I thought all I had to do was insert the camshaft pin and the crankshaft pin and then rotate the engine anticlockwise till it came to a stop on the pin ?
This is what I did ,and both the marks lined up on the casing as well .
Have I missed something as regards the pump?

no need for diesel pump timing with electronic injection :-)

Oh the Irony.

Just when you are hoping that you might have done something wrong , it turns out that you had it perfectly right in the first place!
