Ok , we have had a big uupps momentBackground is that the water pump was leaking on my 200 tdi disco engine in my 90, so while i'm in there I thought to put a new timing belt etc on as it's not been done since my engine rebuild 30k ago.Got everything locked off pump pin and flywheel locking screw, swapped belt, tensioner and idle pully, had tension on belt.Moment of disaster, went to rotate engine a couple of times to even out the tension like it says in the book, I positioned myself under the vehicle and removed flywheel locking screw, my not to glamorous assistant thenrotated engine but was struggling but managed a turn, at which point I realised to my horror that the pump pin was still in, nnnnooooo.So what I have at the moment is two bent pushrods, (now replaced all)Issue I have is that now with everything set as the book,(TDC etc) when I rotate the engine by hand ,cylinder one valves are both closed, engine rotates,valves nos 4 and 6 are hitting the pistons.I have taken off the belt again loosened the rocker to allow up wards movement re set tdc and locked flywheel with pin, put the cam shaft on it's mark, locked the fuel pump. put belt back on and tensioned, removed locks and rotated the engine and it still does it, after reading some posts about possibly being 180 deg out, I have reset tdc and locked flywheel (with the belt off) rotated the cam one turn, re set on the marks etc belt back on it still does it.I'm at a loss to know what else could have slipped, with the rocker off, the engine rotates by hand as it should and feels ok no knocking or clunks, i'm trying to sort without taking the head off or the engine out, but I didnt have any issues with the timing when I re built the engine, i;e cam on its mark ,tdc with the flywheel and pump pins etc, so not sure how much credance to put into the 180 degree out stuff I have seen on some posts.
