Evening.
Very slowly building a 998 engine. All fairly standard. Got the crank bearings ground, new rings, nothing fancy.
Built the block up, no problem. All span well. Stuck the gear box on and didn't think to turn it over till today when I was putting on the flywheel, now I can't turn the stupid thing over.
It seems to turn 359degrees then hits something. Seems to be around the bottom stroke of 1 and 4 cylinders (you can turn it till it stops, go all the way back, then it stops at about the same place). Going to pull it apart Friday and have a root about, but any ideas what I should look for?
Ta for any advice.
