200tdi won't start
Axetamer:
Been thinking about this, I reckon that the mysterious missing lift pump arm has picked up between the camshaft and the cam followers, causing the broken rocker arm and bent pushrods on 7 and 8. I'm gonna whip the engine apart tomorrow in situ ( weather dependant), and see if my theory is right. So its rad out, head off, vac pump and skew gear out along with the timing belt cover and odds and sods, pull followers and camshaft ...& whatever....see what damage has been done.............I'm also thinking pull the whole motor and recon..peace of mind...assuming a full recon( worst case senario) pistons, rings, all bearings, valves, pushrods, camshaft, skew gears, oilpump, seals etc, with no regrind/boring... with standard parts £350ish?

If you're dropping the camshaft out you'll need to separate the engine from the gearbox as the ladderframe bolts into the gearbox bellhousing - only way to remove it to get to the camshaft is to split the two :roll:

Wouldn't that be the Crankshaft? Surly the camshaft is up top and drawn though the timing case from the front?

I am not an engine mechanic but have stripped a couple tdi's, I can easily imagine that the missing lift pump arm briefly locked the cam which cause the timing belt to jump, break or loose teeth and you get the classic bent rods/broken rockers. Is it possible that damage could just be restricted to replacing the bent rods and rocker, new timing belt, timing reset and retrieval of the loose arm. Cam/bearings,belt, bent rocker shaft, rocker shaft pillar mounts fixings may need close inspection. Would be interested in a professional opinion posted on this thread though.
