Timing housing removal

Hi all,

Bit stuck at the moment trying to split the timing housing from the block? All the timing gears are off, camshaft pulley hub is off, all the bolts are out that I can see. Oil pressure relief valve is still in, but don't think that should matter?

I've tried hitting it as hard as I dare, it's not budging in the slightest. Also tried driving a flathead between it and the block, because they are ally it just deforms. Anybody give me some tips on how to get it off, other than hit it harder?

presume sumps off

if its the same as a 200tdi then there are 3 bolts through from the front of the sump

and oil pick up pipe

Sump is off, oil pickup pipes are off, big end and main bearings are all off.

there must be a bolt or 2 left in the case then

Obvious answer is correct! Missed a bolt in the 10mm thick coating of oil and mud in the timing case
