Rack gator problems are because on fully out there's a vacuum (well, not enough air) and on fully in there's trapped air causing it to bend outwards. I assume air should be able to pass between both ends, which means I've put too much grease in to the rack and it'll be getting stripped down fully and rebuilt - may need new arms too as they've been hammered over the flat part of the rack a couple of times now...
Also the engine block wasn't clean enough for the Hammerite so all that has been removed.

Dont think air should be able to move thru it, as i filled mine with a grease gun.

some rack gaitors have a vent hole. before you clip the gaitors down it might be woth lifting up the small end to let any vacuum/pressure out. if that fails im out of answers as it obviously shouldnt be doing that.

Cheers brucer, maybe that's why my previous racks were fine then as they all had a slight slit in the gator! Looked like a cut/hole but maybe the rack fitter did it to fix the problems I was having.
See here for the thread about the problem: http://www.pngclub.com/forum/showthread.php?t=133728
Aaaanyway, that problem is fixed now. I have rebuilt my rack in to a spare housing I have and all is well, it's currently getting a lick of paint and then it's done! No pics as it looks exactly the same. lol
I have wasted the weekend fixing my Volvo but did manage to pop to Autosprint to collect my parts:

Lots of material has been removed from the back, looking at my 'before' pic a few pages earlier:

Crank has had some material taken off to balance up:

He also modified my conrods as requested so I can fit these:

-
Not had it off the crank to weigh it yet, will let you know.

Just to made sure its not tolight..

Benjamin the guy knows his stuff, dont worry. :-)

looks pretty handy, this mr autosprint.

Yeah he's very helpful and keen to offer advice so the engine is built properly.
The flywheel weighs just over 5kg by the way Benn. Can't be more accurate on my bathroom scales, sorry!
